Deutsche Telekom has launched Voice-over-LTE (VoLTE) for customers with a contract and a VoLTE-ready smartphone. The provider will not charge extra for the use of VoLTE. The service is available for calls to mobile as well as fixed networks.
The following smartphones offered by DT currently are compatible with the new service: the Samsung Galaxy S5, S6 and S6 Edge; the Microsoft Lumia 950 and 950 XL; and the Sony Xperia Z3, Z3 Compact, Z5, Z5 Compact and the Z5 Premium.
Deutsche Telekom is the last of the three major operators in Germany to launch VoLTE. O2 and Vodafone started the service last year.
