We have ATT and haven't had to many problems. They are just expensive. We're off contract now and have thought about moving to straight talk or something like that. we pay 110 ish dollars a month for 300 min and 200 texts a piece. Not worth it IMO. I just don't want to go through the hassle of getting a new phone. Mostly because I have a Rugby phone which has stayed alive for 3 years. Which is almost impossible with me. I threw it against a wall once and put a hole in the wall. It still works. I'd have to get a new phone and it wouldn't surrvive as long. That or I would have to stop throwing it when I get pissed.
