T-Mobile, Reliance Jio, and Syniverse Complete First 5G Standalone Roaming Connection

T-Mobile, Reliance Jio, and IPX provider Syniverse have successfully demonstrated the world's first live intercontinental 5G standalone (SA) roaming connection. The successful test linked T-Mobile's network in the United States directly with Reliance Jio's network in India using Syniverse's IPX infrastructure. This connectivity allows devices roaming between the two operator networks to process data and signaling entirely on 5G core technology.

Key facts

• First live 5G SA roaming trial: T-Mobile, Reliance Jio, and Syniverse established the first intercontinental 5G standalone roaming connection between North America and Asia.
• Independent core architecture: The connection routed traffic through Syniverse's Global IP Exchange (IPX) without relying on legacy 4G LTE core infrastructure.
• Network capabilities: The implementation enables native 5G features across international borders, including reduced latency and network slicing functionality for roaming users.

The transition toward native 5G standalone roaming across global telecommunications networks highlights the growing demand for fast international data connectivity. As mobile operators modernize their core infrastructure to deliver high-speed networking worldwide, international travelers and remote workers require immediate access to mobile internet without relying on physical SIM swaps or complex roaming agreements.
