Wi-Fi Calling doesn't work

[iMikes]

I can't use WiFi calling! PLEASE HELP!

I have a z flip 3, my wife has an S22 ultra. Both of us have WiFi calling enabled, but no matter what we do, it calls through the network and not WiFi. We live in an area with very poor network so the line is always bad. We need WiFi calling to work. 

My work around used to be to turn on Flight mode and then turn on WiFi, and this would automatically prioritise WiFi calling. But in a recent update, samsung have removed this ability. So now when you turn on flight mode and WiFi, if you try to make a call, you get a message telling you that flight mode must be turned off first. This wasn't a problem in the past but now we're screwed. What do we do?

I had this same issue. I went into settings > General Management > Reset > Reset Mobile Network Settings.  That fixed the issue.

simply the wifi calling on one ui 7.0 android 15 is working with bugs.

1- receiving calls and receiving sms through wifi calling in airplane mode is working.

2- sending sms through wifi calling in airplane mode is working.

3- making calls through wifi calling in airplane mode is not working. phone automatically disables airplane mode and switches to mobile network.
