There is most definitely a major problem on campus. It's been going on for about three weeks (not counting the poor, but working data since early this year). I've got two coworkers and myself all with AT&T that can't call, receive calls, or text with any reliability. One is an iphone 3G, one a 4S, and one a cheap AT&T flip phone. The phones, as noted above aren't the issue. Once I get home to South College Station, I have no problems with texting or calling.
The only time that I've had these kind of issues was when the fiber on campus was damaged. There is a very similar problem again. One of those coworkers has already complained and gotten a credit. I've been with AT&T since a while back during the Cingular days. I'll be shopping around other carriers next week. I've gotten a pretty good deal by being there so long, but if I can't use the phone, the deal is useless. I'd rather have a slightly worse set up that works regularly than the garbage that I have now.
