Interview with Ari Rabban of Phone.com and Brian Cassano of Tango Networks | Hosted by Doug Green, Technology Reseller News
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.
