Pros: Best Coverage around, Doesn't lock phone features, Rollover, No roaming fees, Best Phones, good service plans, doesn't use up minutes to use internet, Global Roaming
Cons: Most people around here have verizon, spotty 3g coverage
Summary: At&t gets the best coverage of any provider in my high school and almost everywhere else I've used it. It lacks 3g coverage in the upstate but I've found EDGE(2.5g) to be plenty fast enough unless your planning on watching tv on your phone or something. Even then you can watch smooth streaming video with at least 4 out of 5 bars (which i have almost everywhere). It is very very rare for me to not have signal. Even when traveling out of state. And unlike companies like Verizon, where ever you have signal, internet access is always present.
