AT&T advertises they have a superior network but in reality the service is very limited in some areas and states. I was traveling in the Northeast and while on the highway going between Connecticut and New York to Manhattan, I found their 4gLTE service was very poor and the data speeds were less than 1.5 meg during the daytime. In some states it exceeds 7meg. I also use a Sprint cell phone and so far no issues.
The carriers are all in a contest to grab customers. The best thing to do is use the one that is best in your area and ignore the hype
