On my Galaxy S22 (unlocked), when i have wifi calling turned on, almost every time i leave my home wifi i stop receiving SMS messages.
Rebooting the phone will fix it... But this is not a solution, because im not going to restart my phone *every* time i leave my house.
My only solution is to turn off wifi calling, but then i have horrible service in my house.
Something is broken about the wifi to cellular SMS transition, please fix.
