Pros: Consistent voice quality, decent signal radius
Cons: cell phone plans are expensive in general, data plans are scams unless you get the best.
I have to say I havent had too many problems with at&t, but between all cell phone companies trying to pick the best one is more or less trying to pick the less of two evils it seems. At&t has always been the strongest carrier available pretty much anywhere I go, and thankfully they seem to offer some of the most reasonable pricing and benefits with their plans, and their phone selection is probably the best out of all the carriers.
I wish overall prices would drop, it seems as if the industry has fixed a certain pricepoint that no one is dipping under...Anyways I have 4 lines and maybe around 750 minutes a month - but with rollever, nights & weekends, and free calls within subscribers...I still end up racking more rollover minutes each month, but I admit I'm not a big talker.
