Data Roaming vs. Wi-Fi

Syniverse Supports AT&T’s 3G Decom with Inbound Voice Roaming

Syniverse, a premier global technology provider of mission-critical mobile platforms for carriers and enterprises, 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. AT&T announced in 2019 that it would retire its 3G service by decommissioning its circuit-switch-based network.

For mobile operators worldwide that still require the use of circuit-switch fallback, implementing 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 who do not have VoLTE roaming support.

Evolved Mobility solution

With Syniverse’s Evolved Mobility solution, both the visited and home networks can maintain the method of roaming that best suits them, 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 precious spectrum to accommodate increasing 4G and 5G bandwidth demands of mobile devices and Internet of Things (IoT) devices that are emerging across all verticals. For more than three decades Syniverse has managed the transition from each generation of mobile network techniques. With Evolved Mobility, Syniverse continues to drive innovation and interoperability across the mobile ecosystem.

In August 2021, Syniverse announced its plan to go public through a merger agreement with M3-Brigade Acquisition II Corp. (NYSE: MBAC). On January 10, 2022, Syniverse and MBAC announced that MBAC’s special meeting of shareholders to approve the merger is scheduled to be held on February 9, 2022. On January 7, 2022, MBAC commenced mailing of its definitive proxy statement to its shareholders of record as of January 6, 2022. Upon closing of the transaction, the renamed Syniverse Technologies Corporation will be listed on the New York Stock Exchange under the ticker “SYNV.”
