AT&T taps Syniverse ahead of 3G network shutdown

AT&T will shut down its 3G network in February 2022, making way for 5G spectrum and services. But other operators worldwide, whose customers roam onto AT&T, still require the use of circuit-switch fallback, and that’s where Syniverse comes in. On January 25, Syniverse announced, in collaboration with AT&T, the development and deployment of a solution that preserves inbound voice roaming after AT&T phases out its 3G network on February 22, 2022. The 3G network is based on circuit-switched technology as opposed to VoLTE, which is what 4G LTE networks use. For mobile operators worldwide that still require the use of circuit-switch fallback, implementing Syniverse’s Evolved Mobility solution will ensure customers seamlessly connect when roaming on AT&T’s network after the 3G network shutdown, according to the vendor. AT&T is the first customer for this but if Syniverse has anything to say about it, it won’t be the last. The Tampa (FL)-based vendor is holding discussions with other operators, according to Brian Beach, senior product management director for Syniverse.
