Make calls over Wi-Fi

About Wi-Fi calling

Some carriers support Wi-Fi calling to make and receive calls and text messages from locations where your cellular signal is poor or not available. Contact your carrier to confirm that they support Wi-Fi calling for your phone.

Calls and texts that are made over a Wi-Fi network use your existing cellular rate plan, even when roaming:

  • Calls and texts to numbers in your home country are charged the same as your regular cellular calls.
  • Calls and texts to international numbers are charged at international rates.

When connected to a Wi-Fi network, your phone automatically switches between cellular and Wi-Fi networks for calls and texts based on the signal strengths.

Turn Wi-Fi calling on or off

If your carrier supports Wi-Fi calling, you need to turn it on.

  1. Go to Settings > Network & internet > Mobile network.

  2. Touch Advanced > Wi-Fi calling.

    Depending on your carrier, the Wi-Fi calling setting may be in your Phone app at > Settings > Calls (or Advanced Calling) > Wi-Fi calling.

    If you don’t see this option, your carrier doesn’t support this feature.

  3. If your phone has dual SIMs, touch the SIM to set up for Wi-Fi calling.
