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 mobile 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 mobile rate plan, even when roaming:

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

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