Verizon Wireless and AT&T have announced that they are working on enabling Voice over LTE (VoLTE) connections between the Verizon Wireless and AT&T networks. VoLTE provides enhanced calling features and call quality for users of compatible handsets such as the iPhone 6 and iPhone 6 Plus, but traditionally such enhanced features have been limited to users on each carrier’s own network, effectively dropping down to the more basic standard cellular call connectivity when calling users on another carrier.
The proposed interoperability, due sometime in 2015, will allow AT&T and Verizon customers to make VoLTE HD Voice calls between networks, while also laying the foundation for Rich Communications Services (RCS) such as video calls and expanded text messaging features. Both Verizon and AT&T introduced an initial rollout of VoLTE services earlier this year, and customers in select markets with compatible hardware should already be able to take advantage of some of the VoLTE features within each carriers’ own network.
T-Mobile has also reportedly already been testing interoperability across carriers, although that company has not announced a specific timeline as to when interoperability would be available. [via Engadget]
