I've managed to connect WiFi calling just 3 times. Is it that the Smarty SIM is flakey? Can a SIM wear out? I've got a strong wifi signal. I have zero network signal in my area and depend on wifi calling. Should I change my SIM or network provider?
I found a work-around by setting my phone to 'Aeroplane mode' thus forcing my mobile to use only the WiFi signal and now I get wifi calling. I switch it back when I'm in a good network signal area.
