I live rurally and cell service is really not a thing here, so wifi calling has been a godsend.
To make it work:
I turn off wifi calling in settings on my iphone 11.
Then I reset network settings.
Once the phone is back on, I first turn off cellular data, then once wifi is restored, toggle wifi calling back on.
This method has mostly worked like a charm. Keeping the cellular off prevents the phone from searching in vain for a cell signal that will never be strong enough for an actual call (if cellular’s left on, occasionally the phone will “think” that the signal is strong enough, but it never actually is).
To my question: despite numerous iterations of the above resets, including updating to the latest ios, I cannot make wifi calling work at all. The cell signal either says “no service” or “SOS only,” not “Koodo Wifi” as it should.
Please advise! Thanks!
