I have been with at&t , nextel , and now verizon..In that order..
I’m going back to at&t real soon..I do believe that what they claim
is true..IMO More bars in more places..I ride around with my cousin
in Tampa a few times every month , helping him out with his business..
He has coverage way better than what I get with my Verizon..
Also I had better coverage in the woods where I hunt with at&t..
Around here Nextel/Sprint was the absolute worst
