DOCOMO launched in September an inbound 5G roaming service to allow foreign mobile operators and their customers visiting Japan to roam on DOCOMO’s 5G network.

Syniverse is using its IPX Network as a core solution to enable DOCOMO’s 5G roaming service. The Syniverse solution reduces complexity and delivers end-to-end quality of service to ensure roaming and interworking for mobile services, with a secure and reliable network connected to more than 750 mobile operators in more than 150 countries.

DOCOMO plans to actively collaborate with other foreign mobile operators around the world to gradually expand the number of countries where travelers to Japan can enjoy seamless 5G roaming service. 5G service is rapidly becoming more prevalent around the world with more than 105 commercial launches resulting in 7% penetration with one-third of the population to be covered by 5G networks by 2025, according to the GSMA.

The Syniverse IPX Network and Diameter Signaling Services serve as the bridge between 4G LTE and 5G since the two technologies will have to interoperate for many years to come. Syniverse provides active mediation services enabling mobile operators to launch 5G roaming, providing the critical 4G to 5G interoperability required. Syniverse has also developed and launched a 5G roaming hub
