St. Petersburg, FL - Phone.com, a leading provider of cloud-based communications solutions for small businesses, has announced the launch of ProSIM, a new service that enables users to make and receive calls and text messages from their business number using the native dialer of their mobile device. The announcement was made during a podcast interview at Cloud Connections 2025, held in St. Petersburg. Developed in partnership with Tango Networks, ProSIM delivers a fully integrated business line over an eSIM—eliminating the need for a separate app. According to Ari Rabban, CEO of Phone.com, the new offering “revolutionizes mobile communications by bringing UCaaS capabilities to the native smartphone interface, offering simplicity, compliance, and reliability for workers on the move.” Brian Cassano, Vice President of Channel Success (Americas) at Tango Networks, highlighted the opportunity for small business customers. “ProSIM lets businesses extend their UCaaS platform natively to mobile devices. It works seamlessly with features like Apple CarPlay, voice commands, contact integration, and text messaging, while delivering enterprise-grade compliance including HIPAA and SOC 2.” ProSIM is immediately available to existing and new Phone.com customers. For current users, the feature can be activated from the customer dashboard by scanning a QR code to install the ProSIM eSIM. Once installed, users can maintain two lines on a single device—one personal and one business—without switching apps. The companies noted that the product is especially valuable for “workers on the move,” including contractors, healthcare professionals, and frontline staff. By using the cellular network instead of relying on Wi-Fi or data for VoIP applications, ProSIM ensures consistent, high-quality communication without the common drawbacks of app-based calling. “This isn’t just a technical advancement—it’s a workforce solution,” said Rabban. “Whether you’re a solo entrepreneur or part of a mobile team, ProSIM makes it easy to separate business and personal communications while delivering the reliability small businesses need.” Phone.com is actively seeking new channel partners who want to bring ProSIM to small business customers.
