T-Mobile is Designed Data Strong™ and for crystal clear calls. With the latest tech, we’re clearing the way to new levels of coverage and voice quality—like no network has before.
With Wi-Fi Calling, it’s like every Wi-Fi connection is your own personal tower, so you can call and text anywhere in the world you can connect to Wi-Fi. That’s big.
Voices sound more natural and background noise is reduced when you use HD Voice. Thanks to the fastest nationwide 4G LTE network, conversations are more true-to-life and frustration-free.
Calls get high-tech with our nationwide “voice over data network.” Expect call setups nearly twice as fast as non-VoLTE calls, plus you can make calls and use 4G LTE data at the same time!
