Wi-Fi Calling error message

If you are unable to successfully activate Wi-Fi Calling or update your E911 address, it is likely because you are not receiving adequate Cellular signal on your iPhone. Even when Cellular is turned on, the device may sometimes lose signal. The Wi-Fi Calling feature can only be activated on a Cellular network:

What can I do?

Check your iPhone’s service icon to confirm there is at least one bar of service.

  • If you're not receiving Cellular service at the moment, check to make sure that Cellular Data is turned on and that Airplane Mode is off.
  • If your signal is weak, move to a spot where it's stronger.
