In a significant advancement in the telecommunications industry, T-Mobile US (NASDAQ:TMUS), in partnership with Deutsche Telekom (OTC:DTEGY) Global Carrier and Sunrise, has successfully tested 5G Standalone (5G SA) roaming. This breakthrough, which utilized Deutsche Telekom's Security Edge Protection Proxy (SEPP), marks the first-ever successful hosted SEPP 5G SA roaming globally.

The testing involved interconnecting with Sunrise and AIS Thailand. After months of collaboration, the companies completed tests between the U.S. and Switzerland and the U.S. and Thailand. This achievement enables users on participating networks to enjoy a superior 5G experience while traveling internationally.

Ulf Ewaldsson, President of Technology at T-Mobile US, emphasized the benefits of 5G SA roaming. He noted that it offers faster speeds, increased reliability, supports emerging technologies like network slicing, and ensures customers' home network experience travels with them.

The testing carried out by T-Mobile, Deutsche Telekom Global Carrier, Sunrise, and AIS Thailand is seen as a pioneering step in terms of roaming capabilities. While not commercially available yet, it is viewed as a natural progression in enhancing the mobile experience while traveling and for conducting business operations abroad.

5G SA roaming promises an enhanced customer experience with faster speeds, lower latency, and higher capacity compared to Non-Standalone (NSA) networks. It also offers global reach and connectivity, allowing operators to expand their reach and offer seamless high-speed connectivity to their subscribers in foreign countries.

Nicholas Nikrouyan, VP of Voice & Mobile Solutions at Deutsche Telekom Global Carrier, stated that their Hosted SEPP capability has proven very successful during their PoC phase last year. Saran Phaloprakarn, Head of Mobile and Consumer Products Department at AIS Thailand, views 5G SA Roaming as a highly innovative service for ultra-fast data transmission.
