Had similar problems with my P6P. There are multiple areas in my town where I show full / nearly full bars, but my service is terrible or non-existent (!). If I toggle Airplane Mode, I’ll get great speeds until it drops out again. Sometimes this is 30 seconds, sometimes 30 minutes, sometimes hours/days. But at some point it will drop out again. Ugh…
4G
5g
The screenshot cut off my top bar, but i have almost no “bars” on 5g almost ever. And very unreliable connection
Same I turned 5G off, it’s a marginal speed boost but my actual signal strength is shit.
