How Wi-Fi Calling works in simple terms

  • With the use of a Wi-Fi network, your iPhone connects to your iCloud account.
  • On your behalf, Apple’s iCloud connects to the network of the called customer (AT&T, Verizon, Sprint, or T-Mobile) using cellular towers.

Basically, Wi-Fi covers the connection to Apple’s infrastructure and the rest takes place over the good old cell towers through Apple on your behalf. It’s a great extension for covering cellular dead zones while on Wi-Fi.

Test that your Wi-Fi calling is set up properly

  • Turn your iPhone into Airplane mode (swipe up and click Airplane icon in control center)
  • Enable Wi-Fi to connect to your Internet (tap on wi-fi icon in control center)
  • See that your network carrier icon shows without showing LTE or bars for the cellular signal. See the image below for full understanding and compare it to the regular cellular icon in images above.
  • Make a phone call to ensure you’ve done everything properly

There are many other uses for Wi-Fi calling. Especially interesting is Wi-Fi calling through connected devices (e.g. MacBook, iPad, Apple Watch) where you don’t need your iPhone to be around when calling from these connected devices. With the roll out of iOS 10.3, Verizon is expected to join AT&T, Sprit, and T-Mobile who already enable this advanced feature of Wi-Fi calling, (Wi-Fi calling through connected devices).
