WIFI Calling Preferences Being Forced to Cellular Preferred

Same here (GS9+ from VZW, recent switch)

Thanks for the workaround, but T-Mobile needs to fix this from their side. I understand why they do this - i.e. for E-911, you should ideally always call from a cellular signal if available because then they can triangulate your position in an emergency - but I travel a lot (even with this ridiculous pandemic), and when I'm roaming that would be an extra cost.

The ideal workaround will be for T-Mobile to have any emergency call be forced over cellular regardless of this preference (and fall back to Wifi as a last resort), but all calls normally go over Wifi if that is preferred, and NOT MESS WITH THIS SETTING.
