I have a Samsung s22 ultra with an esim. When trying to activate wifi calling, it says may make a little while then stops spinning and nothing happens. I have a cell signal, have connected to a few routers just in case, and have reset all network settings. restarted the phone, and all current updates have been installed. Nothing works. Any advice would be greatly appreciated..
Not sure how Android devices work, but does it ask you for a address for 911 services? May want to make sure that address is accurate.
Another suggestion, and I am really not sure if it matters, but check to see if location services is enabled, wonder if it tries to locate where you are for initial setup?
