Enhanced Voice Services offers improved voice calling on devices that support it. That includes improved voice call reliability and fewer dropped calls when you’ve got a weaker signal and calls that offer a higher fidelity than the HD Voice calling that T-Mobile rolled out years ago. EVS uses a broader audio frequency range to offer more realistic-sounding voice.
EVS works whether you’re on Wi-Fi or LTE, and T-Mobile touts that its “patent-pending deployment” of EVS means that if your phone supports EVS, you’ll benefit from the feature even if the person you’re talking to doesn’t have an EVS-supported phone.
The T-Mobile version of the LG G5 supports EVS out of the box, and T-Mo updated its Galaxy S7 and Galaxy S7 edge to support EVS earlier this week. The feature will be offered on other phones, too, with plans to have a total of seven EVS-supported phones on T-Mobile by the end of 2016.
As I said yesterday, improved voice calling is big to T-Mobile. It’s been offering HD Voice and Voice over LTE (VoLTE) for some time now, and T-Mobile touts that more than half of the calls made on its network are made using VoLTE and that it offers 40 VoLTE-enabled phones. As a result, it’s no surprise to learn that T-Mobile is continuing to push forward with better voice calling. Not everyone cares about voice calls, but for those folks that do, EVS should be a nice improvement.
