Pros: Their phone service is very reliable
Cons: Their customer service line, a phone tree is terrible and when you complain about it, all they do is apologize but they make no attempt to try and see how they can improve it.
Summary: Whenever I needed to contact AT&T it took me anywhere between 10 to 20 minutes to get through. The phone tree for customer service is very unforgiving. Additionally, I left AT&T because I make very few long distance calls and their charges always exceeded the costs of my calls
