I stopped my xfinity mobile because the service was absolutely dreadful. id have either full bars or none and id always have my friends ragging on my connection to Discord. The conspiracy i had in my head was that i was never using cell service but rather the xfinity service would bounce you around their local wifi spots to provide you service whether you had wifi services on or not. probably not true but it surely felt like it.
Tried Mint and it worked just ok. it was nice because at the time i was using an android soap phone and didn’t need much data.
Recently switched my wife and I to Visible plans. even though it is the same coverage as xfinity mobile and uses the Verizon network, it is a night and day difference in connection quality. at 25 a line, i’m happy with visible. i recall my xfinity lines were 30 each after any ‘deals’.
