AT&T and Verizon users will have the ability to send VoLTE HD Voice calls to each other

ByinAnnouncements | November 4, 2014

Advanced Calling 1.0VoLTE (Voice over LTE) service started rolling out across US biggest carriers earlier this year; however, as with every novelty, it requires quite a lot of effort to work the way it is intended to. Access to the service is still pretty limited; however, we are about to witness a huge step toward its wider availability. In the near future AT&T and Verizon users will have the ability to send VoLTE HD Voice calls to customers of the other carrier.

VoLTE-to-VoLTE connections between Verizon and AT&T

VolteThere is no doubt, VoLTE service is a cool invention. The idea of VoLTE calls is to allow customers to place HD Voice calls, 1-way or 2-way video calls and use voice/data services at the same time. It’s possible thanks to relying on internet for making calls. Sounds pretty simple, but in reality it’s not. In order for the service to work, both users need not only to have phones that support VoLTE but also be on the same carrier.

AT&T customers in Illinois, Indiana, Minnesota and Wisconsin who have the Samsung Galaxy S4 Mini can use VoLTE since earlier this year. The service arrived to Verizon in September and is available to users who have either the Samsung Galaxy S5 or the LG G2. Come next year, though, both carriers will have VoLTE interoperability. In other words, AT&T customers will be able to place VoLTE HD Voice calls to Verizon customers and vice versa.

Verizon and AT&T announced today that they are working on the project but didn’t provide any specific date. VoLTE interoperability is expected to go live in 2015 but neither carrier mentioned even more or less when. That’s probably because the project is still in the phase of development and requires a lot of testing, first in lab environments and then moving to field trials.

As of now, VoLTE is also available to T-Mobile customers on the Samsung Galaxy S5, Galaxy Light and Galaxy Note 3 and the LG G Flex. Sprint subscribers can’t take advantage of the service just yet. AT&T and Verizon cooperation gives hope that at some point in the future the service will be widely available across all carriers and interoperability will be a standard. We sure hope so.
