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.

  2. Tap Wi-Fi calling.

    Depending on your carrier, the Wi-Fi calling setting may be in your Phone app at more options icon > Settings > Calling accounts > your SIM > Wi-Fi calling.

Calling 911 with Wi-Fi calling

Calls to 911 are made over Wi-Fi only if the cellular network is unavailable.

Your phone is associated with an emergency address used by emergency responders when you make a call to 911 over Wi-Fi in the US. It's important to change this address when you change locations.

911 calls made over Wi-Fi may be delayed or unsuccessful if:

  • The 911 system doesn't recognize the address
  • You're experiencing a power outage
  • Your Wi-Fi connection isn't working

ImportantWhen you call 911, always tell the operator your location.
