Set Up Wi-Fi Calling on T-Mobile Phones

No signal? No problem! You’re covered with Wi-Fi calling. Make calls and send texts and media over a Wi-Fi connection. You’ll never be denied by a weak signal again.

For this feature to work, your phone must be connected to a Wi-Fi network.

Wi-Fi Calling is only available for T-Mobile Galaxy S8 and later.

Enable Wi-Fi Calling

No more walking around in circles trying to get a signal.

From Settings, search for and select More connection settings. Touch Wi-Fi Calling, and then touch the slider to enable it.

Following settings are available:

  • Wi-Fi Preferred: Use Wi-Fi for calls. If Wi-Fi is unavailable, use cellular network.

  • Cellular Network Preferred: Use cellular network for calls. If cellular network is unavailable use Wi-Fi.

  • Never use Cellular Network: Use only Wi-Fi for calls. Do not use cellular network, even if available.

Disable Wi-Fi Calling

You are going on a camping trip in the wilderness, where you know there's no Wi-Fi for miles. Disable Wi-Fi calling and return to cellular service. Bon voyage!

From Settings, search for and select More connection settings. Touch Wi-Fi Calling, and then touch the slider to disable it.
