T-Mobile and Jio Achieve World’s First 5G Standalone Roaming

Bellevue: T-Mobile and Jio made wireless history today, achieving the world's first 5G Standalone (SA) roaming connection, enabled through interoperability with Syniverse.

This enables T-Mobile customers to experience true 5G SA roaming while traveling internationally — a first anywhere in the world. 5G SA roaming delivers faster speeds, lower latency and more reliable connections, paving the way for transformative applications in IoT, real-time communications and immersive technologies that depend on consistent, high-performance global connectivity.

This achievement was made possible by Syniverse's connectivity platform, which ensures secure, seamless interconnection between networks and helps accelerate global adoption of next-generation roaming.

"This is a monumental step for global wireless, and T-Mobile is proud to lead it," said Ankur Kapoor, Chief Network Officer at T-Mobile. "We started this journey back in 2020, laying the groundwork for a 5G Standalone future — and today, we're continuing that leadership with Jio India as a partner on a global stage. Leave one country, land in another, and your 5G experience is just as seamless — whether you're streaming, sharing travel reels or running business apps. That's the breakthrough power of this technology."

“This is a transformational milestone and far more than just roaming—it’s about what becomes possible when two leading 5G Standalone networks work together. T-Mobile and Jio are laying the foundation for a new generation of cross-network capabilities and services, from differentiated consumer and enterprise experiences to AI-enabled services, leveraging the unique capabilities of 5G Standalone. This is the future of 5G SA: seamless, interoperable, and built to unlock new value.” Said Mark Yarkosky, Head International Network, Partnership and Services, Jio.
