Can’t quite figure all this out. Are you still having the problem?
I understand it’s an old flip-phone, not iPhone or Android. WiFi being on or off should definitely not matter. Very different form of communication from cellular.
Cellular signals can be interrupted in a wide range of ways. I once had a situation where my signal strength dropped 2 bars at home and wouldn’t go back up for over a week. I’d keep dropping calls, if I moved around. And even when standing in one place, the signal strength would fluctuate. It turns out… there was a police trailer temporarily placed on an adjacent block. They had a few communications dishes on top. Who knows what EMF they were generating. Anyway, once they were gone, the interference vanished.
