Telefónica Germany Migrates 4G/5G Voice Services of First 100K Customers to Mavenir Cloud-Native IMS Technology

RICHARDSON, Texas, May 19 (Bernama) -- Mavenir, the software company building Cloud-Native, AI-by-design mobile networks, today announces that Telefónica Germany has successfully migrated the first 100K mobile customers to 4G/5G voice services on Mavenir’s cloud-native IMS solution built on the Amazon Web Services (AWS) Cloud. Telefónica Germany is now the first mobile operator in Europe to deploy such a capability with production subscribers in a public cloud. The migration milestone was achieved in Q1 2026 as part of a multi-year transformation project spanning both fixed and mobile IMS networks.

Under a multi‑year contract extension announced with Telefónica Germany in February 2025, Mavenir began extensive lab validation ahead of moving the operator’s 4G/5G voice services in Germany from Mavenir’s virtualized IMS (vIMS) to Mavenir’s cloud‑native IMS platform. Both companies are developing a comprehensive automation framework, which is expected to streamline operations and accelerate the delivery of new features and updates. During 2026, Mavenir expects to migrate the first few million mobile customers to the new solution running on AWS Cloud. The full migration is scheduled for next year, with all sites set to be deployed using automation.
