My experience with AT&T in my smaller city has improved quite a bit and we don't even have LTE yet. It's reasonably quick and reliable with my iPad 4, also my iPhone with iphone extended battery and my JIAYU G3, unlike how it was even six months ago. I'm satisfied and LTE should be that much better. As a whole is just hope nothing breaks or stops working and you need customer service and tech support. I'd rather have a bunch of chimps through crap at me than to deal with that hell again.
