Unlocked version of the HTC 10 supports T-Mobile's VoLTE and Wi-Fi calling13
If you're a T-Mobile subscriber, you have a choice. You can pre-order the unlocked model from HTC, or wait for the carrier-branded variant to go on sale. Both models will be released next month. AT&T subscribers don't have that choice. As we told you this morning, the nation's second largest carrier is not selling a carrier-branded version of the phone. AT&T subscribers can still purchase the unlocked HTC 10.
If you are a T-Mobile subscriber contemplating the purchase of the unlocked HTC 10, you might wonder if the phone will support T-Mobile's VoLTE feature and Wi-Fi calling. We could ask Bill Nye the Science Guy for the answer, but he probably doesn't have a clue. Luckily, HTC's VP of product management, Mo Versi, sent out a tweet with the answer. Both VoLTE and Wi-Fi calling are available for T-Mobile customers rocking the unlocked HTC 10. The latter allows you to use Wi-Fi to make phone calls in areas where T-Mobile has a weak cell signal. The former allows calls to be made over the 4G LTE network. This allows for the use of HD voice and provides improved audio quality for your phone calls.
For the last three weeks, we've been hearing that HTC is obsessed with the camera, battery life, and audio for the HTC 10. Now, how many of you are obsessed with the phone?
