AT&T has tied up with Syniverse for the development and deployment of a solution that preserves inbound voice roaming after AT&T phases out its 3G network on February 22, 2022.
AT&T announced in 2019 it would retire its 3G service by decommissioning its circuit-switch based network.
Deployment of Syniverse’s Evolved MobilitySM solution will ensure customers seamlessly connect when roaming on AT&T’s network after February 22, 2022. Implementing this solution ensures a better customer experience by avoiding disruptions when roaming for those roaming subscribers that do not have VoLTE roaming support.
Syniverse’s Evolved Mobility solution will support both the visited and home network to maintain the method of roaming, meeting the needs of both operators and end users. This includes facilitating voice and short message service (SMS) and the clearing, settlement, and near-trade as well for a full end-to-end solution.
Decommissioning circuit switch networks like 3G frees up spectrum to accommodate increasing 4G and 5G bandwidth demands of mobile devices and internet of things (IoT) devices that are emerging across all verticals, Bob Chiodo, General Manager of Americas Carrier Division, Syniverse, said.
“AT&T has been in the process of phasing out its 3G network. To ensure voice roaming services after a circuit-switch decommission, we collaborated with Syniverse to create an innovative solution that could preserve customer experience,” Cameron Dunn, Director of Mobility Inter-Carrier Architecture and Development, AT&T, said.
