These days I’m exclusively working from home, my wifi and internet access are pretty good, but cell coverage is spotty.
So on work calls all day my phone battery was getting killed w the weak cell signal and occasionally I drop a call.
I have AT&T, enabled WiFi calling on my iPhone and put it into airplane more with WiFi on, no more dropped calls, perfect sound, and battery life is crazy good now. Worth a try if you have WiFi calling with your phone and carrier.
