I was basically forced to switch to AT&T when my sister attended a college that only had reception from AT&T. I switched from Tmobile and noticed a substantial difference in connection. I have been on AT&T for about 4 years and I have no issues with its reception, but they have messed up on billing the account quite often. Luckily, the workers at my local AT&T usually have nothing to do because the store is always empty, so they are happy to help us. My siblings then changed to Verizon and whenever I compare reception it is exactly the same. I might have one less bar from time to time, but for the most part I am up to par if not higher than him. Oh yah, did I mention the bill is 1/2 of the price that my siblings are paying for? In general, I am happy with AT&T except it is a bit of a dishonest company that puts limitation on phones (i.e. no sideloading and you know the rest)
