T-Mobile rolls out next-gen voice technology EVS

It's official. T-Mobile is deploying Enhanced Voice Services (EVS), a successor of the current mobile HD voice codec AMR-WB. EVS uses complex speech compression algorithms and was designed to provide higher-quality audio than is currently available over cellular networks.

T-Mobile CTO Neville Ray disclosed the updated VoLTE usage data in a blog post yesterday. The LG G5, which launched late last week, was the first T-Mobile handset to support EVS, and Ray confirmed that the Samsung Galaxy S7 and S7 edge recently began to support the technology through a software update.

EVS improves voice call reliability where signal strength is lacking, resulting in fewer dropped calls, and works on both Wi-Fi and T-Mobile's LTE network. For more, check out FierceWireless' coverage here and here.
