Well the t mobile support guy had me reset everything but still at one bar. I didn’t have problems with drop calls on the 11 pro max but I do now i literally have to sit by a window to get a good reception to make a call.. super strenuous!!
My bro have 5G and has full bars in the house.. just like u said they may not have a tower near but I doubt it.. I live New York Manhattan to be exact and there’s towers everywhere. The tech tried to help me but he failed
