@Three_Shane1 I don't appear to be able to receive or make calls when in Airplane/Flight mode, if I attempt to make a call with Flight mode on, I'm then prom[ted to turn it off before I can make a call. My device is an S22 which is compatible.
@Vin2022 I've moved your question from the Idea's board to our discussion board.
Yes, your device is compatible with WiFi Calling but have you gotten the text to confirm it is activated on your account? If not I would suggest contacting our care team on 1913 to get it added.
