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.
