While many professionals rely solely on their personal cell phones, mixing personal and business calls can lead to missed messages, unprofessional impressions, and unnecessary stress. In this article, we’ll explore why having a separate business line is essential, compare options like eSIMs and VoIP apps, and explain how to find a reliable business phone solution provider.

Why You Should Have a Separate Business and Personal Phone Number

It may seem convenient to use your personal number for business calls—but doing so comes with several drawbacks:

• Professionalism: Customers and clients expect a business to have a dedicated line. Answering calls from your personal number can appear unprofessional.
• Privacy: Using one number for both work and personal calls exposes your personal number to clients, partners, and potentially unwanted callers.
• Work-Life Balance: A single number means work calls and messages could reach you 24/7, making it hard to disconnect.
• Organization: A dedicated line ensures your business calls, texts, and voicemails are separate, making it easier to track communications, invoices, and follow-ups.

By having a mobile business phone number, you create a clear boundary between your professional and personal life while projecting a polished, credible image to clients.

eSIM vs. VoIP App: Choosing the Right Mobile Business Phone Number

Once you decide to get a separate business line, you have two main options: using an eSIM or a VoIP app. Both provide a business number on your mobile device, but there are important differences.

VoIP Apps

VoIP apps, like Google Voice, Skype, or other softphone applications, offer a way to add a second number to your phone without a physical SIM.

Pros:

• Easy to set up and often free or low cost.
• Can work over Wi-Fi and mobile data.

Cons:

• Call quality depends on internet connection.
• Some clients may not recognize the number as a local business line.
• Limited integration with mobile device features like SMS, MMS, or carrier-based call handling.
• Often requires keeping the app open for calls to work correctly.

eSIM Technology

An eSIM (embedded SIM) allows you to add a second phone line directly to your mobile device without swapping physical SIM cards. The business number operates natively on your phone.

Pros:

• High-quality voice and SMS functionality, identical to your primary line.
• Works seamlessly with your phone’s built-in features, including contacts, call forwarding, voicemail, and messaging.
• No reliance on third-party apps or constant internet connection.
• Supports multiple numbers on a single device while keeping personal and business communications separate.

Cons:

• Requires a compatible smartphone (most modern iPhones and Android devices support eSIM).
• Usually requires a provider that supports eSIM provisioning.

Why eSIM is Often the Superior Choice

For most professionals, an eSIM-based mobile business phone number offers a more seamless, reliable, and professional experience. Unlike VoIP apps, you don’t have to worry about dropped calls, limited SMS functionality, or clunky app interfaces. Calls and messages appear as native interactions, giving you the look and feel of a fully separate device without the hassle of carrying one.

How to Find a Business Phone Solution Provider for Mobile Business Numbers

Once you’ve decided on an eSIM-based mobile business phone number, finding the right provider is key. Here are factors to consider:

1. eSIM Support

Not all business phone providers offer eSIM provisioning. Look for providers that explicitly support eSIM for mobile business numbers, ensuring your line can operate natively on your device.

2. Business Phone Features

Check that the provider offers:

• Call routing and forwarding
• Voicemail transcription and notifications
• Auto-attendants or virtual receptionists
• Team extensions or additional lines if your business grows
• SMS and MMS support for texting clients

3. Reliability and Coverage

Ensure the provider delivers strong network coverage and uptime. Your mobile business phone number should function just like a regular mobile line, without dropped calls or lag.

4. Ease of Management

A provider with a user-friendly mobile app or web dashboard makes it easy to manage calls, messages, and settings from anywhere.

5. Scalability

Choose a provider that allows you to add more business lines or extensions as your team grows. Scalability ensures your solution will meet your needs long-term.

Getting Started with Your Mobile Business Phone Number

Setting up a mobile business phone number with an eSIM is straightforward:

1. Verify eSIM Compatibility: Ensure your smartphone supports eSIM technology.

2. Choose a Provider: Research business phone systems that offer eSIM provisioning. Look for features that align with your business needs.

3. Activate the eSIM: Typically involves scanning a QR code or following simple activation instructions from your provider.

4. Configure Your Settings: Set up call routing, voicemail, business hours, and any automated greetings.

5. Share Your New Number: Update your website, business cards, and email signature with your dedicated business line.

Once active, your mobile business phone number will function seamlessly alongside your personal number, allowing you to maintain professionalism while staying fully connected on the go.

Conclusion

A mobile business phone number is no longer optional for modern professionals—it’s essential for professionalism, privacy, and organization. While VoIP apps provide a simple option, an eSIM-based business number offers superior call quality, integration, and reliability.

By selecting the right business phone solution provider that supports eSIM provisioning, you can enjoy all the benefits of a dedicated business line without the hassle of carrying multiple devices or juggling apps. Separate your personal and business communications today, project a professional image, and take full control of your business communications on the device you already carry everywhere.

Thanks to advances in eSIM technology and modern business phone system providers, it’s now easier than ever to keep your professional and personal communications separate—all on the same device. In this post, we’ll explore why a dedicated business number on your cell phone makes sense, how eSIM plays a role, and the many benefits it brings to your business.

Why You Need a Business Phone Line for Your Cell Phone

If you’re still using your personal number to handle business calls, you’re not alone. Many freelancers, consultants, and small business owners start this way. However, as your company grows, the drawbacks become clear:

• Lack of separation: You can’t easily turn off work calls when you’re off the clock.
• Unprofessional appearance: Customers may question your credibility when you answer from a personal line.
• Limited features: Your cell carrier doesn’t provide business features like call routing, auto-attendants, or voicemail transcription.

A business phone line for your cell phone gives you the professionalism, features, and flexibility you need—without having to carry two separate devices.

What Is an eSIM and Why Does It Matter for Business?

An eSIM (embedded SIM) is a digital version of the physical SIM card that connects your phone to a carrier’s network. Instead of swapping out cards, you can activate new lines instantly by scanning a QR code or entering a few settings.

For business users, this means:

• You can add a second phone line on the same device in minutes.
• No need to carry two phones or juggle SIM cards.
• You can keep your personal line and add a business phone line for your cell phone through an eSIM.

Many modern smartphones—including iPhones and Android devices—support eSIM technology. When paired with a business phone systems provider, eSIM makes it easy to manage multiple numbers, profiles, and features from one device.

How Business Phone System Providers Fit In

Adding a line with eSIM is only the first step. To truly unlock the benefits, you’ll want to partner with a business phone systems provider. These companies specialize in delivering professional-grade features to mobile users, such as:

• Call routing and forwarding: Send calls to your business number wherever you are.
• Voicemail-to-email or text transcription: Stay organized without listening to endless messages.
• Virtual receptionist/auto-attendant: Greet customers professionally, even if you can’t answer.
• Team extensions: Give employees their own numbers or extensions—all under one system.
• Video conferencing and messaging integration: Keep everything tied into one communication platform.

With a provider handling the back-end, your business phone line for your cell phone works seamlessly alongside your personal number without extra hardware.

Benefits of Using a Business Phone Line for Your Cell Phone

Let’s dive into the core benefits of combining eSIM technology with a business phone systems provider.

1. Professionalism and Credibility

When clients see a dedicated business number—rather than a personal mobile number—it signals legitimacy. It shows that you’ve invested in your company and are ready to serve customers professionally.

2. Work-Life Balance

Having a business phone line for your cell phone allows you to silence work calls after hours without missing personal calls. You can set specific business hours, route after-hours calls to voicemail, or forward them to a call answering service.

3. Cost-Effectiveness

Traditionally, businesses would buy separate phones or expensive desk systems. With eSIM and business phone systems providers, you can have two lines on one phone—often at a fraction of the cost.

4. Flexibility to Scale

Need to add more employees or departments? Your provider can issue new numbers or extensions instantly. You don’t need to worry about adding more hardware.

5. Advanced Features

From call recording to team messaging, a business phone line for your cell phone gives you enterprise-grade features that a personal line can’t match.

6. Security and Privacy

Using your personal number for business opens the door to spam, robocalls, and potential data privacy issues. A dedicated line keeps your personal number private while still allowing full business accessibility.

Example Use Cases

Here are a few real-world examples of how a business phone line for your cell phone can be a game-changer:

• Freelancers: Keep personal and client calls separate without juggling two phones.
• Real estate agents: Use a business line with call routing so clients always reach someone available.
• Consultants: Maintain a professional image with a business voicemail greeting and dedicated line.
• Small business teams: Provide employees with numbers tied to your company account.

Setting Up a Business Phone Line on Your Cell Phone

Here’s a simple roadmap to get started:

1. Check device compatibility: Make sure your smartphone supports eSIM (most modern devices do). Also make sure your phone is unlocked by the primary mobile service provider.

2. Choose a business phone systems provider: Look for features like call routing, voicemail transcription, and virtual receptionist.

3. Activate the eSIM: Your provider will send instructions, usually involving a QR code.

4. Customize your settings: Set up call forwarding rules, business hours, and voicemail greetings.

5. Share your new number: Update your website, email signature, and marketing materials with your new business phone line.

What to Look for in a Business Phone Systems Provider

Not all providers are created equal. Here are some features to prioritize:

• Ease of use: It should be quick to get started and set up your eSIM
• Reliability: Uptime guarantees and strong call quality.
• Scalability: Ability to add or remove lines quickly.
• Support: 24/7 customer support for peace of mind.

Future-Proofing with eSIM and Cloud Phone Systems

The future of business communication is cloud-based and mobile-first. By adopting an eSIM-powered business phone line for your cell phone, you’re investing in flexibility and scalability. As technology evolves, you’ll be able to add advanced features like AI-driven call analytics, smarter routing, and enhanced security—without ever swapping devices.

Final Thoughts

A business phone line for your cell phone is no longer a luxury—it’s a necessity for entrepreneurs, freelancers, and small businesses that want to appear professional, protect their privacy, and stay flexible. With eSIM technology and a reliable business phone systems provider, you can have the best of both worlds: one device, two lines, and all the advanced features you need to grow your business.

Instead of juggling personal and professional calls, let technology work for you. With the right setup, your cell phone can become the ultimate business communication hub—without sacrificing your work-life balance.

The Phone.com business line for your cell phone is called ProSIM. You can add it to your Phone.com plan for just an additional $10 per month.

Enter eSIM for business, a smarter way to extend your professional phone system directly onto your smartphone without depending on shaky apps or data connections. ProSIM, an innovation available through Phone.com, uses a device’s native dialer and the mobile voice network to deliver business-grade call quality, security, and simplicity. If your business depends on being reachable anytime, anywhere, it’s time to rethink how mobile communication should really work.

Why eSIM for Business Changes the Game for Mobile Teams

Businesses that operate on the go need more than an app; they need communication that’s as mobile as they are. Traditional VoIP apps weren’t designed for field-based professionals who can’t afford to lose calls when Wi-Fi falters or apps crash. That’s why eSIM for business, and specifically ProSIM, represents such a breakthrough. It delivers native, carrier-grade reliability alongside all the essential features of a business phone system. Let’s look at why this mobile-first approach is a true game-changer.

The Rise of Mobile-First Businesses

With 54% of employees wanting to work fully from home and 41% preferring hybrid, remote work is now the norm. From solo entrepreneurs to multi-location small businesses, the ability to work anywhere without missing calls, texts, or meetings is a basic requirement. Yet many solutions built for office-bound teams still leave mobile users scrambling for stable connections.

ProSIM flips the script by making the mobile network, not just the internet, the foundation for business communication. No hunting for hotspots. No desperate refreshes. Just seamless, native connectivity everywhere you go.

Why VoIP Apps Fall Short in Real-World Use

VoIP apps can seem attractive until real-world friction shows up. Poor audio quality, dropped calls when Wi-Fi weakens, background app crashes, and battery drain are all common complaints. For mobile businesses, these aren’t minor inconveniences; they’re barriers to client trust and operational efficiency. Because ProSIM operates over the mobile voice network, it avoids the typical pitfalls of data-dependent apps, giving businesses a truly professional edge no matter where work takes them.

ProSIM: Instant Activation and Native Dialer Power

Installing ProSIM is simple: scan a QR code, activate, and your business line is ready to use via your phone’s native dialer. No separate apps. No second-rate experiences. Making a business call feels exactly like making a personal call: familiar, fast, and intuitive. When employees are juggling multiple tasks on the road, that simplicity becomes a serious productivity boost. With ProSIM, your mobile device truly becomes a seamless extension of your business communications.

ProSIM vs. VoIP Apps: Real Pain Points Solved

For mobile-first businesses, the daily frustrations of app-based calling can quickly add up to real operational risks. ProSIM was built to address those real-world pain points directly, offering business owners and teams a more reliable, secure, and seamless communication experience without the headaches of app dependencies or unstable Wi-Fi. Here’s how ProSIM delivers where VoIP apps often fall short.

Reliable Call Quality Without Wi-Fi or Data

Mobile professionals know that data connections can be unpredictable, especially when traveling between urban centers, rural areas, and job sites. A video meeting cutting out or a call dropping mid-client conversation can damage your credibility. An eSIM for business uses the cellular voice network rather than internet data, ensuring strong, consistent call quality wherever mobile coverage is available. It’s a difference your clients will hear immediately.

Unlike VoIP apps that prioritize convenience but compromise stability, ProSIM provides carrier-grade reliability without tying you to a Wi-Fi hotspot. Whether you’re in an airport lounge, a client’s driveway, or a construction site, you can trust that your calls will connect clearly the first time—no app buffering, no redialing, no apologies needed.

Battery Drain and App Glitches? Not Here

Running a VoIP app all day in the background is notorious for draining mobile battery life faster than typical usage. Plus, constant switching between personal calls, business apps, and messaging platforms creates friction and opens the door to glitches or crashes at the worst times. ProSIM eliminates this strain by integrating your business line directly into the phone’s native dialer, reducing app bloat and preserving valuable battery life.

By removing the dependency on a separate application, ProSIM keeps your device lighter, faster, and ready for longer workdays. When you don’t have to worry about your phone dying halfway through a service call, property showing, or client meeting, you can focus fully on growing your business instead of managing your tech.

Built-In Business Features: Caller ID, Extensions, and More

With traditional VoIP apps, basic business features like branded caller ID, call routing, and voicemail management can require juggling multiple platforms or accepting functional compromises. The right eSIM for business connects seamlessly to cloud PBX systems, meaning you can enjoy business-class capabilities right from your phone’s normal interface.

That includes setting up a professional business caller ID (showing your company name or number, not your personal line), using extensions to route calls across a team, and managing voicemails easily through the standard phone app. No extra logins, no clunky workarounds. With ProSIM, your smartphone becomes a true business tool, not just a second-best backup.

Mobile Business Case Studies: Who Thrives with eSIM Solutions

While any mobile professional can benefit from better call quality and simpler phone management, some businesses stand to gain even more. For industries where mobility, responsiveness, and professionalism are mission-critical, adopting eSIM for business is a competitive advantage.

Let’s look at a few types of businesses that are thriving thanks to eSIM-powered communication.

Field Workers: Contractors, Landscapers, Home Health Providers

If your team spends more time on the road than at a desk, ProSIM transforms how business gets done. Landscapers rushing between client sites, contractors managing job crews, and home health providers visiting patients all depend on quick, clear communication. Wi-Fi dead zones and unstable apps can create dangerous delays or missed instructions. ProSIM’s mobile-first design ensures that these critical calls connect fast and stay strong, wherever the workday leads.

More importantly, ProSIM allows field-based workers to present a consistent, professional caller ID and maintain seamless communication without switching between personal and business devices. With everything unified under one mobile experience, your brand stays polished, even when the workday gets chaotic.

Remote Entrepreneurs: Coaches, Freelancers, Traveling Consultants

For entrepreneurs who build businesses from coffee shops, airports, and client offices, first impressions matter. A dropped call or a voicemail buried in a glitchy app can be the difference between landing a deal and losing it. ProSIM gives remote business owners the tools they need to maintain professionalism and dependability, no matter what the day throws at them.

By integrating their business line directly into their phone’s main dialer, freelancers and consultants enjoy a truly native experience with professional caller ID, call forwarding, voicemail, and texting without hopping between apps. It’s a solution designed for modern entrepreneurs who refuse to compromise on image or opportunity.

Real Estate and Service Professionals on the Move

Realtors showing properties, insurance agents handling claims, and traveling service providers like home inspectors and cleaners all have one thing in common: every missed call is a missed paycheck. ProSIM ensures that incoming calls from prospects, clients, or partners are never lost to spotty apps or Wi-Fi issues.

Plus, service-based professionals often juggle multiple conversations throughout the day. With eSIMs, your voicemails, texts, and business calls stay organized and easy to manage from one simple place: the device you already carry. The result is faster response times, stronger client trust, and a reputation for being reachable when it matters most.

Security and Compliance on the Go

When it comes to mobile business communications, quality and convenience are only part of the equation. Security and compliance are just as critical, especially for industries handling sensitive information like healthcare, legal services, or financial consulting. ProSIM was built with these priorities in mind, offering encrypted, carrier-grade voice services without the vulnerabilities that can plague VoIP apps and unsecured networks.

For mobile businesses that care about safeguarding client data and maintaining a clear line between personal and professional communications, eSIM for business is a necessity. Here’s how ProSIM keeps your business protected while you stay on the move.

ProSIM’s Secure, HIPAA-Compliant Calling

Unlike traditional mobile apps that rely on internet-based calling, ProSIM routes all calls through the cellular voice network, leveraging the encryption and security protocols already embedded in mobile infrastructure. Your calls are protected at a much deeper level, reducing the risk of eavesdropping, data breaches, or other security vulnerabilities common with open Wi-Fi networks.

For industries governed by strict data protection standards like HIPAA, SOC 2, or GDPR, ProSIM offers an important compliance advantage. You get business-quality security for every call, without needing your team to jump through complicated setup steps or rely on third-party app security settings. Security is built-in, not bolted on.

Keeping Business and Personal Lives Separate on One Device

Another overlooked security risk is mixing personal and business communications on the same phone number. When employees use their private mobile numbers for client calls, it blurs professional boundaries while complicating data management and compliance. ProSIM gives mobile professionals a fully separate, dedicated business line on the same device without needing to swap SIM cards or carry two phones.

This dual-persona setup keeps personal calls private and business communications protected under your company’s unified system policies. It also improves team management, making it easier to maintain oversight of business numbers, call logs, and text records when needed while preserving employee privacy for their personal use.

Getting Started with ProSIM is Easier Than You Think

Switching to a better solution shouldn’t feel like another project on the to-do list. Thankfully, getting set up with ProSIM is fast, intuitive, and hassle-free. There are just a few simple steps, and you’re ready to work smarter from anywhere.

Whether you’re equipping yourself, a few employees, or an entire mobile team, ProSIM makes it easy to upgrade your communication strategy without slowing down your operations. Here’s how the process works.

Quick Setup with No Hardware Hassles

You don’t have to wait for SIM cards to ship or buy extra hardware just to get a business line on your phone. ProSIM uses eSIM technology, meaning you can activate your service instantly by scanning a QR code sent directly to your inbox. In a matter of minutes, your new business line is ready to use.

Because ProSIM operates through your mobile phone’s existing hardware, there are no bulky accessories, no worrying about losing tiny SIM trays, and no downtime while switching devices. Whether you’re activating one line or dozens, the process is designed to be efficient so you can focus on your customers, not your tech stack.

Simple Management for Growing Teams

As your business grows, managing multiple business lines across your team should be just as simple as setting up the first one. With ProSIM, adding new users, managing phone numbers, and configuring call settings can all be done centrally through an easy-to-use online dashboard.

This centralized management system gives business owners and office managers full visibility and control without micromanaging every device. Need to assign a number to a new field rep? Done. Need to update caller ID for your sales team? Easy. ProSIM’s simplicity at scale ensures that your communications evolve as fast as your business does without missing a beat.

Say Goodbye to VoIP App Frustrations — Your Business Deserves Better

Mobile businesses can no longer afford to settle for unstable apps, battery drain, and unreliable call quality. Clients expect seamless communication, and your team deserves tools built for the way they actually work. With ProSIM, powered by eSIM for business technology, you gain the reliability of the cellular voice network, the security of business-grade encryption, and the simplicity of using your phone’s native dialer.

At Phone.com, we believe mobile professionals shouldn’t have to choose between flexibility and professionalism. ProSIM was designed to be easy to activate, simple to manage, and powerful enough to meet the demands of fast-moving businesses. Let’s get you connected with a solution that truly works where you work. Explore ProSIM today and see how effortless business mobility can be.

“With ProSIM, we’re solving a real pain point in the UCaaS market,” said Rabban. “While apps work for some, many small business users simply want to make calls directly from their phones—securely and professionally—without any hassle.”

Powered by Tango’s eSIM technology, ProSIM integrates the full feature set of the Phone.com platform—including call routing, recording, compliance tools, and dual business/personal identities—directly into a phone’s native dialer. This allows mobile-reliant professionals—such as frontline workers, healthcare providers, and contractors—to stay securely connected through a business-grade phone system using the device they already carry.

“We’re enabling people to work how they already prefer—but smarter,” added Essex. “ProSIM makes your business number feel like it’s truly part of your phone, enhancing usability, mobility, and regulatory compliance.”

Designed for small businesses seeking speed, simplicity, and security, ProSIM offers an incredibly fast setup. “Just visit Phone.com, sign up, choose your number, and you’re operational in minutes,” said Rabban.

The service is also built with regulatory needs in mind, offering HIPAA-compliant features, secure messaging, real-time call transfers, and robust call management—all from a mobile interface.

Both Phone.com and Tango Networks see this as the foundation for a larger vision: delivering AI-powered, mobile-first business communications that keep pace with the evolving needs of modern professionals.

On April 23, 2025, our CEO, Ari Rabban had the opportunity to sit down with Dave Michels and David Danto of TalkingPointz, a VoIP industry thought-leading analysis and research organization, to discuss the launch of ProSIM. ProSIM by Phone.com revolutionizes the way users can utilize their mobile devices for business purposes.

The interview explores the concept of “UCaaS Mobility 3” and how this approach offers benefits such as a native dialer experience, enterprise-grade features, and the ability to utilize the cellular voice network for both traditional mobile calls and UCaaS. Dave Michels, who coined the phrase “UCaaS Mobility 3,” describes how the VoIP industry evolved from the initial idea of mobility —a fancy version of forwarding often called “find-me-follow-me”-to dedicated VoIP apps, which are the norm today. ProSIM takes mobility to the next level by eliminating the need for VoIP calling apps while still providing all the business communication features users need.

Phone.com Launches ProSIM

Introductions and Phone.com Background

David Danto: Welcome, everybody. This is David Danto. I’m here with Dave Michels. We’re both from TalkingPointz, and today we are going to have a special guest join us. It’s going to be Ari Rabban, who is the CEO of phone.com. Why are we interviewing him today? Dave?

Dave Michels: I’ve been talking a lot about this thing I call “UCaaS Mobility 3.” Now, I have to say, I think UCaaS Mobility 3 is the best name for it, but no one other than me uses that term, but I’m going to stick with it because it’s a good term, and we’ll explain what that is. But when I’ve been talking about it, I’ve been saying it’s going to be the future. All the big UCaaS providers are going to be all over this, and certainly Microsoft and Cisco have made their waves, but I said, if you’re not a big player, you’re not serious unless you’re doing this. And so fa,r I’ve been wrong. But Ari, from Phone.com (probably the best name in the business), said, “Hey, I’ve got UCaaS Mobility 3.”

He called it something else, because only I say UCaaS Mobility 3. But anyway, I said, “This is great. Let’s get on a webcast and talk about it.”

Welcome, Ari.

Ari Rabban: Hello Dave and David!

Dave Michels: Okay, well, you’ve, you’ve got a great name. And I’m not talking about ProSIM, I’m talking about Phone.com. So let’s start off there. So, how did you get that name?

Ari Rabban: I was working with Jeff Pulver, and by the way, I’m in Cape Cod now at a Jeff Pulver conference. Industry professionals are familiar with the name. Those outside the industry should know that he was one of the pioneers of the voiceover IP industry. And he founded the V conferences. Working with him, I met the individuals who purchased the domain Phone.com, led by Michael Mann, who aimed to build a business using that name. I had the idea for Unified Communications as a Service or business solutions in the cloud for small businesses. We partnered, and the rest is history.

UCaaS Mobility 3

Dave Michels: Alright, well that was early history. And current history is ProSIM. So let me just take a moment here and explain this basic concept of UCaaS Mobility 3. My basic, the basic premise is that UCaaS and Mobility have always gone together to some level. And so UCaaS Mobility one version one was basically creative call forwarding and we called it things like Find-me, Follow-Me. It was basically a very fancy form of call forwarding and it was a great solution for impound calls. It didn’t work so good for outbound, but it was a pretty good solution. That was UCaaS Mobility 1.0. UCaaS Mobility 2.0 is what most people consider normal today, which is having an app on your smartphone that allows you to make and receive business calls on your personal cell device.

It works pretty well. It was a big star during the pandemic. A lot of us worked at home and whether we had a cell phone or a laptop, we were able to make and receive calls using our apps. And that worked out just fine. It doesn’t work particularly well in a lot of situations, particularly people that are actually mobile who are driving down the interstate, going between towers and things like that doesn’t work really well. And so UCaaS Mobility 3 is the concept of putting the UCaaS service on the native SIM service, whether it be hard or soft in a cell phone and giving you a true quality of service on your UCaaS line.  And so Cisco has it, they call it WebEx go. Microsoft has it, they call it Microsoft Teams phone mobile. And now Phone.com has it. And so let’s start off with a little bit of a background on Phone.com. You are not Cisco or Microsoft, how are you different?

Ari Rabban: We punch above our weight partly because of our name. Phone.com is a service provider that focuses on the needs of small business. I would say even micro businesses, one to 10 employees. We do serve some larger accounts. We have businesses with over a hundred or 200 employees. We work, we scale, but our sweet spot and most of our customers, we have about 50,000 small businesses, accounts customers on our platform. Most of them find us online, they sign up touchless. We do have a 2.4/7 call center. We’ll support you, we’ll provide a lot of love and care. I think that’s why a lot of small business like us, it’s a full phone service in layman’s terms, a business phone service with of course all the bells and whistles of modern technology. And we want to keep ahead of the curve and this is why we are here today with our new ProSIM service.

Dave Michels: I probably got it wrong because I was all excited about UCaaS Mobility three and the enterprise space, but it’s actually the smaller businesses that are really mobile. I mean, your customer profile I imagine has a lot, including business owners and almost every employee in some cases is living on their mobile phone. Is that accurate?

Introducing ProSIM

Ari Rabban: Yeah, I think first of all, in our industry there’s a huge distinction that I think isn’t made a lot or enough between a small business America, the 20 plus million small business America that keeps America going and the enterprise world, which is of course on business level probably more interesting to most of the large competitors. And just in general, you want to attract the big businesses. Mobility is of course not the same for folks who sit in front of a desk and have a laptop all the time. They have steady WiFi or very strong broadband, they can use the laptop. We certainly all learned how to do that during the pandemic. So you don’t have to be a techie anymore to use video conferencing or what have you. But again, there are millions who need mobility and can’t rely on data for steady and important calls. And the phone is their main business tool. 

Dave Michels: So when you announced this a week ago, how do you describe it? 

Ari Rabban: So it’s a good question because there is some education to do here. Many folks, as you said, don’t even know what an eSIM is or even a SIM. They know they had the card, the slot that they use the pin to open and replace when they changed phones.

Once you put on the cover on the iPhone or the Android phone, you don’t know what’s underneath you. I was surprised to see folks even that you think they’re a little more tech savvy, didn’t know that there is no slot anymore. But the findings that we had for a long time is that the apps that we all provide as an industry get complaints because they just cannot be as good as a cellular service.

Dave Michels: Let me explain that. Your cell phone does not have what we, in the internet world called net neutrality. The cell phone has different priorities of service and they always prioritize their own services first. So the SIM service, the core service, which is telephony and messaging, have a higher quality of service and will work in a bad congestion area or between highway or handoffs, much better than the internet connection, which is what they call a best effort service. So people that are running their mobile apps, their UCaaS apps on the best effort side, find out that they have a lot of dropped calls, particularly when they’re moving around. And at some point you say, forget it, I’m just going to call you back on my cell number or just call me back on my cell because that’s going to work better. We, we’ve all experienced that. And so we just give up on the other side. So you’re putting the other side, the UCaaS concept onto a SIM card. And so the question is, how many hours does this take to explain to the customer? And then inevitably they’re going to say, yeah, but it works fine. I’ve had this conversation a few times, it works fine with my app. I don’t need your service. And so I kind of have my experience, but I want to hear how you’re doing with this. 

Ari Rabban: So first of all, besides the general curiosity and innovative aspect of what we all do and we want to offer new services, there’s demand. We have, like I said, it’s 50,000 businesses and they’re using the apps and we get complaints. It’s not working, it’s not working, there’s a problem. But at the same time, FaceTime didn’t work or WhatsApp didn’t work. In other words, it’s your data. It’s not that the app is not working. I’m not saying we’re perfect, but certainly data is an issue. So we knew that there has to be some solution. We were looking for opportunities to partner with companies that could help with eSIM and mobility technology. And eventually we found the company that we thought fit like a glove. They’re Tango Networks and great folks from Dallas.

Dave Michels: I’m still interested why you did it. So I’ve got here a banner going across the screen, some UCaaS Mobility 3 benefits, quality of service. That’s the one I talked about, native dialer. Why don’t we talk about native dialer? 

Ari Rabban:  First of all, the behavior of the customer, of a user, is that they don’t want to go to an app to make a call. You want to just use your native dialer. This is how you make a call from your iPhone or your Android phone. So check mark, now we have it. And in all other UCaaS or business phone solutions, second-line options are not available. And the second thing, which is extremely important, is that we are part of the service, not a standalone second line that you can get from any other operator. We are a business solution that has all the capabilities and the functionality of a business phone solution with recording, with extensions, with the ability to monitor the calls, with of course, compliance. So HIPAA is very important for the medical professions, there are SOC II and others for financial and other organizations, all such that if you just make a call on your mobile phone, you might not be able to do it.

Even if you’re a microbusiness, a healthcare professional, or a financial professional, you just can’t make a call like that. The functionalities related to monitoring calls are all about business. Again, you might not be a big business, but you have three or four employees. They’re more important to you than employees of a big company. When they call on their cell phone, you don’t have the leads, and you don’t have the contact information for those folks when they leave the company. It could be a plumbing business, and that plumber will receive the calls, not the business.

Saying Goodbye to the Two Phone Method

Dave Michels: I keep on meeting people that are carrying two phones around and I say, why are you carrying two phones around? And it’s always the same thing. I don’t want enterprise software on my phone. You don’t have to put enterprise software on phones with ProSIM because it’s in the SIM. And so I have it on my phone and when I make a call, it says, “hey, you want to make an outbound call, which SIM do you want to use?” And if I pick one SIM, it has that outbound phone number, it’s on that service. I didn’t pay for it, it didn’t cost me anything out of my minutes or anything like that. And if I pick the other SIM, it goes out that number. And if the business is managing things and logging things like when you’re talking to customers and stuff like that, they only see your work calls. Exactly. And so you still have your personal device without any company software. It’s to me so fricking obvious, but I need people like you to explain this to customers. 

David Danto: Let me be the Devil’s Advocate then, because if I go back to my history, when I worked for an enterprise, you had this one on my left waist and this one hanging on my right waist and this is us and this is them, and they have the ability to wipe their device. If I quit the company, but they don’t have the ability to touch my device. If I’m calling another company and getting an interview, how are you going to convince me as the user of this, that if I combine these to a single phone, that the privacy is going to exist both for the company side and if I’m calling my family or an interview at another job or something like that, how do you keep them separate? How do you convince me?

Ari Rabban: That’s essentially the question. The answer is that with our service, you can guarantee that to some extent. When you use one phone, you have your personal Gmail account and your work email. If by mistake, you use your work email to send an email to a relative or a friend, the company has it, but we all know how to distinguish because you have this, call ita Chinese wall, this is work, this is a private personal, and it’s the same device. That’s what’s happening now. You do everything that you want in your personal life with line one, and then you use line two for your business. The experience here is that of using a tool that is the most popular in the world: the iPhone or Android. You don’t need to learn UCaaS; you are using the iPhone. So, if there is education here, it’s to educate the audience about the capabilities of the iPhone, not those of any other enterprise solution. The US market, in our case, I think Europe probably is a little more advanced, but we’ll catch up with dual SIM.

Dave Michels: To answer David’s question a little more, the issue is the reason they want to be able to wipe the phone is because of all the enterprise data that is on the phone. Now, in an environment like Teams or WebEx, they can actually do that from the server. They can disable you from the server, disable your client, and they don’t need to wipe the phone. They just need to basically tell the client, not that it doesn’t have access anymore. What Ari’s doing is primarily voice oriented. And so there’s no data on the phone other than call logs and stuff. And that’s tied to the SIM. So his whole value prop is you don’t have to install software on the phone, just install the sim and then the corporate can turn that on and off. And the example that Ari said earlier about the salesman leaves and goes to a competitor and takes his phone number with them. That won’t happen anymore because they’re using their work line with Phone.com ProSIM and when they change jobs, the pro number stays with the company. So there’s no reason to wipe the phone, there’s no reason to, and there’s no reason to carry two phones and it’s cheaper for the enterprise and easier for the employee. 

What does “SMB-foucsed” look like?

So you are SMB focused, and we talked a little bit about how some of your competitors are more enterprise focused people like Dave and I talk about this all the time. SMB play, enterprise play. From your perspective, what does that really mean?

Ari Rabban: For us, the definition of small business is a little different than Goldman or Morgan Stanley. The company is small, revenue is small, and they’re not tech savvy at all. They can’t afford the IT expert, let alone an IT department. The decision maker is usually the owner, and they will decide for themselves and for the few employees they have. So, the whole sale process is entirely different when you work with an enterprise, where they have either their IT department or consultants, and they have to get various people to agree, and then they have to enforce the employees to use it. And it gets more and more complicated than I’m sure there are other decisions that they have to go through, based on compliance or whatever they would think they would need to address.

Dave Michels: We see that a lot of the environment that David and I deal with, the customer has vendor meetings lined up all morning and it’s the Amazon comes in, then Microsoft comes in, and then Salesforce comes in, et cetera. I mean, your customers don’t have that. Your customers are like, look, I’m going to give you 20 minutes here and then I got to go to the Verizon store and solve my problem. It’s like they’re totally on their own. And you’re coming in with this fairly sophisticated solution. I want to hear how customers are reacting once you get past the explanation. You’ve got, I assume you’ve sold somebody on this by now. So you’ve got some customers Tell us how that’s going.

The Locked Phones Challenge

Ari Rabban: So we’ve been testing it before we went live, which was last week. If you visit the website, it’s easy to find us; you’ll see a lot of material explaining our services. There are numerous FAQs, as well as videos and tutorials. We will continue to add and improve them. Again, there is some education on what I said earlier, specifically regarding the capabilities of your smartphone, that allows you to do that. And the second thing is just how do you install an eSIM? Again, it’s not Phone.com or enterprise software, it’s your iPhone.

There is a challenge, and probably the biggest one in the US market, is that many phones are still locked to the agreements of the carriers who fund the phones, and so on. There are over 80 million unlocked phones. It’s increasing. Of course, in many cases, you can request that the carrier unlock, but you have to educate yourself and explain. These are topics that we address and share; our staff is trained to answer them, and all the information is available. And that’s part of why small business also likes us. We love them.

Dave Michels: Now when the phone is locked, and so somebody bought their phone from Verizon and is locked to Verizon, does that usually mean that both SIM slots are locked to Verizon or just or one? 

Ari Rabban: So, it depends. First, you can always ask the carrier to unlock it, and then you can use a different SIM card. They want to make sure you stay with them. There are different ways to do it. Verizon, in many cases, after you purchase the phone, they will unlock it for you. T Mobile and AT&T are different, but in most cases, you also pay monthly fees for the phone. At some point, you can pay it off, and it gets unlocked, and then you can undoubtedly use somebody else’s service.

Dave Michels: So I would say that the United States lags the world in mobile technologies, and this is one of the reasons why United States is pretty much the only country that allows this locking phone nonsense. And you look at certain countries, particularly Scandinavia, where everything is so much more innovation going on, or even mobile World Congress, biggest trade show in the industry is not in the US. It’s in Barcelona every year. And the US it is just so far behind in so many areas of mobility. And so it’s frustrating with the locked phones. Okay, so let’s get to how you did this. So tell us about your partner. 

The Technology Partnership

Ari Rabban: So yeah, we needed a company. We come from the UCaaS space, the cloud communication industry, not the cellular mobile world. And certainly, we don’t deal with SIM cards directly, and that’s all Tango Networks does. And we partnered with them. They saw that vision and they have been a great partner. And so the eSIM technology we use comes from them. Obviously, it’s all software. There’s no hardware to deal with. It’s all automated through APIs.

You get a SIM and then you stick it in your phone or download it and you have a second line. This is a second line that’s part of an entire system behind it. And Tango is that gateway that allowed us to do that. We’re not offering a cheap phone service on a second line. It is inexpensive, but the idea is that it’s part of a business solution.

David Danto: Is it only voice services or can you get data through that second channel? 

Ari Rabban: No we don’t offer data. Our whole idea is we’re not for streaming Netflix or what have you for that, you have your primary line. We’re a secondary line. It is essentially the business service on your mobile with your cellular native experience.  You can send and receive SMS messages.

Use Cases

Dave Michels: What kind of experiences or what are you hearing from your customers about ProSIM?

Ari Rabban:  We have a few hundred users already, and I’ll give you three examples. One company is small, it’s in food delivery, for wholesale and restaurants, and has a few employees. And the owner just said they’re using our app and the services, but it’s just not as friendly when they rely on it all the time. And he wants his employees to use his phone numbers, not their own. So ProSIM was very exciting for him.

Another one is healthcare. They do senior living services, so they don’t want to use their cellular phone numbers. And now it’s like give them a few ProSIMs. It’s a small organization, it’s not one of those big operations with hundreds of employees. It’s HIPAA compliant, so they can use the second line instead of being afraid to talk to patients or to the kids of the elderly or what have you.

And the third is just a frontline worker on the go, that blue-collar person who can now just take the calls, be more relaxed, and enjoy the reliability, quality, and all the other benefits I have.

Right now, you have to be a Phone.com customer, and then you can add the ProSIM.

Dave Michels:  All right. Well, I think we’re going to end this episode, but I just want to be sure that you are explaining to your customers and to your competitors when they’re trying to figure out how to keep up with you, that you tell them it’s UCaaS Mobility 3. That’s the key here.

Introduction & About Phone.com

Rich Tehrani:
Hey, it’s Rich Tehrani, the Tech Authority. Thanks for joining us today. We’re really excited to have the team from Phone.com — Ari Rabban and Amber Newman. Good afternoon!

Ari Rabban:
Good afternoon. Great to be here.

Amber Newman:
Very well, thank you.

Rich:
You’ve got such a great domain name — Phone.com — so it’s pretty clear you’re in the telecom space. Ari, can you tell us more about what your company does?

Ari:
Sure! Phone.com is a business phone service provider, focused specifically on small businesses — from sole proprietors up to teams of 10 or 20. We do have larger customers, but our sweet spot is the very small business community. Our service is largely self-provisioned and comes packed with features. We’ve been doing this for over 17 years.

Rich:
I’ve seen you at nearly every IT Expo in South Florida — always showing up, except maybe once during COVID. So you’re definitely active in the community.

Ari:
Yes, absolutely. We’re strong supporters of the show and the broader community.

Rich:
Amber, tell us a little about your background. How did you get here?

Amber:
I’ve been in the VoIP space for nearly 20 years — starting with M5 Networks, which eventually got acquired by Shortel, then Mitel. I’ve worked with a few other companies that were also acquired along the way. It’s been amazing to see the evolution of business communications, especially for small businesses — which is where my passion lies.

Introducing ProSIM

Rich:
You’ve got a big product launch — tell us about it. Ari, what’s the new product?

Ari:
It’s called ProSIM — and it’s our next-gen offering that integrates UCaaS (Unified Communications as a Service) with native mobile phone service. Instead of relying on a mobile app for business calls, which many do today, ProSIM gives you a second, fully functional business line on your native mobile dialer. Amber can break it down even further.

Amber:
Absolutely. This really solves a major pain point — the hassle of using two phones or relying on mobile apps, which often don’t perform well in areas with weak Wi-Fi. ProSIM enables users to make and receive business calls directly through their native dialer, using an eSIM — no apps needed. It separates personal and professional identities and maintains UCaaS features like hold music, auto attendants, call recording, and HIPAA compliance.

Why ProSIM is a Game-Changer

Rich:
Why was there a need for this solution? What was the problem?

Ari:
Many small business owners don’t want to use their personal number for business. They rely on mobile apps to separate the two, but those apps aren’t always reliable — especially for frontline workers who are on the go. With ProSIM, they get a business line that’s just as reliable as their personal line, without changing behavior.

Amber:
Exactly. Previously, you had three bad options: carry two phones, use an app, or just give out your personal number. ProSIM gives you a fourth — and better — option. It’s the first true desk phone in your pocket. No change in behavior. You just scan a QR code to activate your eSIM, and you’re good to go.

How ProSIM Works

Rich:
So how do you make or receive calls with ProSIM?

Amber:
It’s easy. When you make a call, your dialer lets you choose between SIM 1 (your personal line) or SIM 2 (ProSIM). The phone remembers your last choice, so it’s super smooth. Texting works the same way. Just use your normal messaging app, select the SIM, and go.

Who Is ProSIM For?

Amber:
ProSIM was built for deskless workers — the backbone of small businesses. Our customers don’t sit behind a desk all day, and they can’t be forced into using complicated apps. This solution is intuitive and seamless — no extra steps.

Ari:
We’re seeing early adoption already — healthcare workers, traveling sales teams, and other mobile employees. It’s HIPAA-compliant and gives the business full control of the customer relationship by keeping the business number in-house.

Pricing & Availability

Rich:
What should people know about availability and pricing?

Ari:
You can sign up now on www.phone.com. You need a basic Phone.com account to get started. The first month of ProSIM is free, and after that, it’s just $10 per month. Existing customers can simply add it to their plan.

Other Considerations

Rich:
What about coverage and compatibility?

Ari:
Currently, ProSIM runs on the AT&T network, covering 96% of the U.S. If your main line is on Verizon, ProSIM actually gives you a second carrier option. We’re also looking into unlocked vs. locked phones — and providing educational support to guide customers through setup.

Amber:
And yes, Wi-Fi calling will be available soon. In the meantime, if you’re in a dead zone, you can still fall back on our app. But most of the time, ProSIM will just work on your native dialer without any additional steps.

Final Thoughts

Rich:
This has been fantastic. I love what you’re doing and how you’re helping small businesses stay professional while simplifying their lives. Any closing thoughts?

Amber:
Just that this is finally a desk phone in your pocket — with all the business-grade features you need, but no new behavior to learn. If you have an unlocked phone, it’s as easy as scanning a QR code and you’re up and running.

Ari:
And we’re continuing to evolve the platform — expect more innovation, AI enhancements, and partner integrations in the future.

Rich:
Thank you both for your time — this was a great conversation. I look forward to future success stories and updates from you.

Ari & Amber:
Thank you, Rich!

The post How We’re Redefining Mobile Business Communication: Watch Our Interview with Rich Tehrani appeared first on Phone.com.

Doug Green of Technology Reseller News recently sat down with Ari Rabban, CEO of Phone.com, and Brian Cassano  of Tango Networks to discuss an exciting new product launch: ProSIM—a solution that brings business phone numbers natively to mobile phones. The announcement marks a game-changing moment for small businesses looking for seamless, reliable mobile communication.

A Game-Changer for Business Mobility

Doug Green: You’ve got some big news this morning. What’s the announcement?

Ari Rabban: We’re proud to announce the launch of ProSIM, in partnership with Tango Networks. This new service allows Phone.com customers to use their business numbers as a second line on their mobile phones—natively, without relying on an app. Users can now make and receive business calls and texts directly through their mobile’s default dialer, leveraging the reliability of the cellular network.

Brian Cassano : It’s truly revolutionary. We’re turning the mobile device into a native endpoint of a unified communications platform. With ProSIM, calls and messages from your business number feel as natural and seamless as personal ones—no switching apps, no dropped calls due to Wi-Fi issues, just direct mobile connectivity.

Why Native Dialing Matters

Doug Green: How is this different from using a mobile app?

Ari Rabban: Apps have long been a workaround for mobile business communications, but they come with limitations—dropped calls, reliance on broadband, and a separate user experience. With ProSIM, we eliminate all that. You can now dial from your regular mobile keypad, use your existing contacts, even use voice commands and Apple CarPlay—just like you would for personal calls.

Brian Cassano: This isn’t just about convenience—it’s about quality. Over-the-top apps rely on data connections, which are not always stable. By using the cellular network, ProSIM ensures consistent call quality and allows users to benefit from mobile carrier-grade voice and text messaging, tied directly to their business identity.

Built for Small Businesses on the Move

Doug Green: Who are the intended customers for ProSIM?

Ari Rabban: Phone.com has always focused on the small business and micro-business segment—typically under 20 employees. Whether you’re a coach, contractor, physician, or freelancer, this solution fits. These are people on the go—working on rooftops, inside buildings, or traveling between job sites. ProSIM is a no-brainer for them because it just works, wherever they are.

Brian Cassano: We call them “workers on the move.” They need a communication tool that matches their mobility. With ProSIM, they get all the functionality of a business-grade communication system, while still using their personal device—no need to carry two phones.

Secure, Compliant, and BYOD-Friendly

Doug Green: There are compliance implications too, right?

Ari Rabban: Absolutely. Whether it’s HIPAA in healthcare or financial compliance in other sectors, ProSIM supports these requirements. The platform allows professionals to use their mobile phones for work without compromising compliance or privacy.

Brian Cassano: It also supports Bring Your Own Device (BYOD) policies. Employees can keep their personal numbers private while communicating through a secure business line. It protects both the employer and the employee.

Available Now – Easy to Set Up

Doug Green: Is this service live now?

Ari Rabban: Yes, it’s available right now. Existing Phone.com customers can log in to their dashboard and activate ProSIM by scanning a QR code to install the eSIM. New customers can sign up at Phone.com to get started. It’s simple and immediate.

Channel Opportunity & Future Outlook

Doug Green: Is this a play for the channel too?

Ari Rabban: Absolutely. While we focus on direct-to-small-business sales, we also work with channel partners who now have a much stronger story to tell. Selling an app was sometimes a hurdle. Selling a native solution like ProSIM is a whole different ballgame—it’s familiar and easy to explain.

Brian Cassano: This is a solution that cuts across all industries and all business types. It’s not vertical-specific. Wherever businesses have mobile employees, ProSIM fits. And it’s just the beginning—we’re excited about where this can go.

With ProSIM, Phone.com and Tango Networks are delivering what small businesses have long been asking for: native, reliable, compliant business communications—on the device they already use every day. It’s not just a new product—it’s a new way of thinking about mobile business connectivity.

Interview Transcript

Rich Tarani:
Hey, it’s Rich Tarani. Thanks for watching. We’re at the IT Expo Tech Super Show. The year’s 2025. We’re here in Fort Lauderdale, Florida. On our program is Ari Rabban. He’s the CEO of Phone.com. Ari, welcome back to the show. How are you?

Ari Rabban:
I’m good, thank you. Always great to be here.

Rich Tarani:
And it’s great to have you. You guys are one of the original unified communications as a service providers going back years and years. I mean, you had the foresight to register Phone.com. I mean, so smart. Tell us a little bit about the company. What should people out there know if they haven’t heard of you?

Ari Rabban:
Well, Phone.com is a service provider that focuses on needs of small business. I guess we call us UCaaS. The service is basically offered to any customer in the U.S. Mainly, we acquire customers online. We do have a channel program, so IT firms would register, sign up their customers, but we’d provide the support and all. We’re going 18 years now. I mean, obviously, we’re going with IT Expo. We’ve been in the previous company, VocalTech, which was from the very, very early days.

Rich Tarani:
Yeah, you’ve been in the communication space, voice over IP space, since the inception.

Ari Rabban:
Yes, yes. So we’ve seen a lot and can comment about the changes, always believe in the future. I mean, the industry at large always said, you reach the limit, but there’s always the next phase. And that’s certainly how we still feel. I mean, the energy is there. Customers are still coming. We’re all competing, but it’s healthy.

Rich Tarani:
Yeah, I remember in the early days, you were one of the first companies to deal with compliancy. You became a HIPAA-compliant provider, which was great for medical companies. Then I remember you opened up your solution. So there was API access, allowing other solutions to interoperate with you. So you’ve really been leading the way, certainly ahead of the curve in this space. What’s new and exciting? What are you doing next?

Ari Rabban:
I think we have been in the forefront. We bite what we can chew. I mean, we know our size compared to some of the really big companies, but we are always looking at something new so that we don’t just stay kind of the same. To say AI is—kind of everyone who comes will say AI. I don’t even like the word AI because it’s kind of overused. And our customers, small businesses, don’t really need to know it’s AI. They need to know that they have a new tool that can help them with productivity essentially, etc.
So we absolutely are evaluating different products. I think we’re one of the early ones who put a service that is a receptionist service that is based on AI. We take appointments for you and set schedules, transfer calls. And it’s learning and it’s improving and answering questions, etc.

Ari Rabban (continued):
Solutions that, for us, it has to fit—call it plug-and-play—for a small business, a really small business, kind of under 20 employees, under 10 employees. There’s no IT to ask. It’s our customer service they can ask, but that’s it.

Rich Tarani:
That’s fantastic. And so are there trends you’ve been seeing in the market, just in communications in general or just companies over the last year?

Ari Rabban:
I think the opportunities, again, are there. I think the last year, there was some fear—if I may say so—some change, fear, Microsoft Teams, Zoom. There’s no need to fear, I think. You need to compete and be there. Also, again, depends which company and who you are.
I actually think that some regulatory changes—some are bad. Some could be good. With AI, it’s another area. Obviously, we’re all suffering from fraud, both as an industry and also the customers—the real good customers—and how we can help them and optimize the solutions. So we kind of move that—it’s more than noise aside. So that’s certainly out there, and it takes a lot of attention. Maybe more defense than offense, but it’s very much needed. So you need to work on that.

Rich Tarani:
Great. What else should we know?

Ari Rabban:
Again, for us, the way we look at things—customers, small business—you always say your customer knows what they want, always trust the customer. Sometimes you need to show what’s new. We want to bring tools that are available for larger organizations so that a small company can use it in a simple way.
Right now, we also feel that mobility is something that we all kind of… I think it’s taken for granted and it’s always there, but there’s more we can do and integrating UCaaS and mobility can be done better. And that’s another area that you should expect to hear from us soon.

Rich Tarani:
Fantastic. And people can find you at phone.com.

Ari Rabban:
That’s very easy to find us. Yes. www.phone.com.

Rich Tarani:
Thank you.

Ari Rabban:
Thank you.

The post Innovating Unified Communications An Interview with Ari Rabban appeared first on Phone.com.

Newark, NJ – April 15, 2025 – Phone.com, a leading cloud-based communications provider for small businesses, today announced the launch of ProSIM. This groundbreaking solution seamlessly integrates mobile devices with its robust Unified Communications as a Service (UCaaS) platform. Developed in partnership with Tango Networks, ProSIM delivers true Fixed Mobile Convergence (FMC), empowering small businesses with unparalleled mobile flexibility and control.

ProSIM transforms any compatible mobile phone into a full-featured extension of a business’s Phone.com system using the eSIM (embedded SIM) capabilities of modern mobile devices and the cellular voice network. By leveraging Tango Networks’ advanced technology, ProSIM enables Bring Your Own Device (BYOD), allowing business owners and frontline workers to use their personal mobile phones for business communications without compromising privacy or security. This solution provides a native mobile experience, ensuring seamless call handling, text messaging, and access to essential UCaaS features directly from the mobile device’s dialer.

“ProSIM represents a significant leap forward in mobile UCaaS for small businesses,” said Ari Rabban, CEO of Phone.com. “In today’s dynamic work environment, mobility is paramount. ProSIM eliminates the need for separate business phones and reduces the dependency on a distinct mobile VoIP app. This approach also offers the cost-effectiveness and flexibility that small businesses need to thrive.”

Key Benefits of ProSIM:

True Fixed Mobile Convergence (FMC): Seamlessly integrates mobile devices with the Phone.com UCaaS platform.
Best Call Quality: Use of the cellular voice network eliminates the challenges with Over-the-Top (OTT) mobile apps that rely on mobile data and WiFi.

Bring Your Own Device (BYOD): Enables employees to use their personal mobile phones for business communications.
Cost-Effectiveness: Eliminates the need for separate business phones.

Centralized Management: Provides control over business communications through the Phone.com platform.

Improved Security and Compliance: Ensures business calls and texts, even those subject to HIPAA and SOC II compliance, are routed through the secure Phone.com network.

Addresses the needs of frontline workers: Allows for seamless connection with deskless workers in service and field-work roles.

The integration with Tango Networks’ technology ensures that business calls and texts are routed through the Phone.com platform, providing centralized management, call recording, and analytics. This allows businesses to maintain control over their communications while offering frontline workers the convenience of using their personal devices.

“We are thrilled to partner with Phone.com to bring the power of fixed mobile convergence to small businesses,” said Andrew Silver, Co-Founder and CTO of Tango Networks. “ProSIM leverages our innovative technology to deliver a seamless and secure mobile UCaaS experience, enabling businesses to extend their communication capabilities beyond the office and into the hands of their mobile workforce.”

UCaaS industry expert Dave Michels, Founder of TalkingPointz, has emphasized mobile-first communications and the inevitable convergence of UCaaS and cellular. “It seems normal to have totally separate systems for wireless and wired business communications, but the costs, complexity, and compromises are not normal. Businesses of all sizes will move toward SIM-based UCaaS as their providers enable it. ProSIM is ahead of the pack with a seamless approach to mobile business communications.”

Newark, NJ – April 15, 2025 – Phone.com, a leading cloud-based communications provider for small businesses, today announced the launch of ProSIM. This groundbreaking solution seamlessly integrates mobile devices with its robust Unified Communications as a Service (UCaaS) platform. Developed in partnership with Tango Networks, ProSIM delivers true Fixed Mobile Convergence (FMC), empowering small businesses with unparalleled mobile flexibility and control.

ProSIM transforms any compatible mobile phone into a full-featured extension of a business’s Phone.com system using the eSIM (embedded SIM) capabilities of modern mobile devices and the cellular voice network. By leveraging Tango Networks’ advanced technology, ProSIM enables Bring Your Own Device (BYOD), allowing business owners and frontline workers to use their personal mobile phones for business communications without compromising privacy or security. This solution provides a native mobile experience, ensuring seamless call handling, text messaging, and access to essential UCaaS features directly from the mobile device’s dialer.

“ProSIM represents a significant leap forward in mobile UCaaS for small businesses,” said Ari Rabban, CEO of Phone.com. “In today’s dynamic work environment, mobility is paramount. ProSIM eliminates the need for separate business phones and reduces the dependency on a distinct mobile VoIP app. This approach also offers the cost-effectiveness and flexibility that small businesses need to thrive.”

Key Benefits of ProSIM:

True Fixed Mobile Convergence (FMC): Seamlessly integrates mobile devices with the Phone.com UCaaS platform.
Best Call Quality: Use of the cellular voice network eliminates the challenges with Over-the-Top (OTT) mobile apps that rely on mobile data and WiFi.

Bring Your Own Device (BYOD): Enables employees to use their personal mobile phones for business communications.
Cost-Effectiveness: Eliminates the need for separate business phones.

Centralized Management: Provides control over business communications through the Phone.com platform.

Improved Security and Compliance: Ensures business calls and texts, even those subject to HIPAA and SOC II compliance, are routed through the secure Phone.com network.

Addresses the needs of frontline workers: Allows for seamless connection with desk less workers in service and field-work roles.

The integration with Tango Networks’ technology ensures that business calls and texts are routed through the Phone.com platform, providing centralized management, call recording, and analytics. This allows businesses to maintain control over their communications while offering frontline workers the convenience of using their personal devices.
