Berlin: Mavenir, the software company building Cloud-Native, AI-by-design mobile networks, today announces that Telef³nica 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. Telef³nica 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.

According to BERNAMA News Agency, under a multi-year contract extension announced with Telef³nica 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. This transition marks a significant step in the modernization of telecommunications infrastructure in Europe, setting a precedent for other operators in the region.
