AT&T Rolls out VoLTE in First Markets

AT&T has launched VoLTE and HD Voice in select areas in the District of Columbia, Georgia, Illinois, Indiana, Maryland, Michigan, Minnesota, Nevada, North Carolina, Ohio, Oregon, Pennsylvania, South Carolina, Texas, Utah, Virginia, Washington and Wisconsin. The carrier's first VoLTE rollouts occurred in Illinois, Indiana, Minnesota and Wisconsin earlier this year.

AT&T also noted that its VoLTE is network performing very well.

VoLTE includes the ability to simultaneously talk and surf the web at LTE speeds. VoLTE also allows for higher audio quality for calls through HD Voice.

  • In November, Verizon and AT&T confirmed that they are working to establish VoLTE interoperability between their networks. The companies are working through a full set of requirements, beginning with extensive testing in lab environments and then moving to field trials.  This approach ensures customers will have a seamless experience making VoLTE HD Voice calls between networks and lays the foundation for interoperability of other Rich Communications Services (RCS) such as video calls, rich messaging, and more in the future.

VoLTE interoperability between Verizon and AT&T customers is expected in 2015.
