Got questions?

Wi-Fi Calling allows customers to make and receive calls and texts (SMS & MMS) over a Wi-Fi connection. Using Wi-Fi Calling is easy–customers won’t even know they’re making a Wi-Fi call. Simply connect to an available Wi-Fi network with a Wi-Fi calling-enabled smartphone and continue to make a call or send a text as you would over a cellular connection. No separate app or log-in or number is needed.

Where do we start?  Benefits include:

  • Integrated out-of-the-box experience on T-Mobile capable devices – no extra app necessary
  • Uses your existing phone number – no additional logins necessary
  • Call or message virtually anyone from anywhere you have a Wi-Fi connection
  • Extends coverage in areas where no cellular network reaches
  • Receive and make Wi-Fi calls back to the United States from anywhere in the world at no additional cost
  • Available at no additional charge

First connect to a Wi-Fi network. Wi-Fi Calling is enabled out of the box on most phones. To ensure Wi-Fi Calling is enabled, go to Settings. Look for “More…” or something similar. Tap “More…” and scroll to see Wi-Fi Calling. Toggle to the “On” position. You can also choose whether to make Wi-Fi Calling your preferred mode of calling (default), or use cellular for voice calls whenever strong cellular service is available.

With next-gen Wi-Fi Calling, T-Mobile is pioneering a seamless handover between our LTE network and any available Wi-Fi connection so calls don’t drop between the two. Next-gen Wi-Fi Calling also features HD Voice quality, when calling another HD Voice-capable user.  This means our customers can now maintain crystal clear HD Voice calls, whether connected to T-Mobile LTE or Wi-Fi–all using their existing T-Mobile number.

T-Mobile post-paid plans include unlimited voice so Wi-Fi Calling does not impact minutes. Every customer is set up to use Wi-Fi Calling without any extra effort on their part.

Yes, you must connect to a Wi-Fi network before your phone will automatically connect to that same network when in range. Once you’ve connected, you’ll be automatically connected when Wi-Fi is turned on.

Go to Settings and select Wi-Fi. A list of available Wi-Fi networks will appear. Select a trusted network and enter a password to connect. After the first connection, the phone will automatically connect to that same network automatically when in range.

Yes, when the device is in range of a reliable Wi-Fi network, Wi-Fi calls and cellular calls are similar in quality. In fact, T-Mobile is the only major national carrier to offer HD Voice on Wi-Fi, and VoLTE for crystal clear HD Voice quality.

For Wi-Fi calling to work, a customer must have the following technical requirements:

  • Access to a Wi-Fi router with a high-speed internet connection
  • A Wi-Fi calling-enabled smartphone
  • A valid 911 address on file
