Losing Wi-Fi calling option unless I go airplane mode on then off.

[Fred Zed]

Having an issue whereby my iPhone 14PM doesn’t show Wi-Fi calling indicator sometimes. If I enable and disable airplane mode then it shows Wi-Fi calling until the next time it loses it. All inside my house. This occurred with T-Mobile and now with Tello my new carrier.
I didn’t pay much attention to this issue until today since I can’t receive any calls now unless I’m on Wi-Fi calling. Else if I turn Wi-Fi off and Wi-Fi calling indicator is not present callers receive the following message “ the subscriber you have dialed is not in service “. All this whilst having a strong signal at my or elsewhere.

That was an ongoing problem for me until recently. I would have to force it to wifi calling by going to airplane mode. I've found that iOS 16 improves this tremendously and no longer notice this problem.

Mine is still this way on iOS 16.1 whether I am on T-Mobile or Tello or any carrier.

It stops showing the carrier name Wi-Fi calling intermittently, perhaps it’s my router that’s running in and excuse me for not knowing the correct terminology, mixed mode as is in it doesn’t show SSID 5Ghz or 2.4Ghz it runs a mixture. Maybe this is the issue in regards to why I lose Wi-Fi calling unless I go into airplane mode and off ?

So in essence the issue is the my device doesn’t show the carrier name followed by Wi-Fi calling unless I turn on and off airplane mode.

It's still not working on 14Pro 16.2. Must turn-on airplane mode. But then need to remember to turn it off when leaving home. That's not how it was supposed to work.
