This has to be THE WORST DESIGNED APP EVER !!!!! For ATT to be such a huge company, you would think they would hire somebody that could fix this. Most of the time it won't even let me into the APP to pay my bill, it just loads and loads then when you get into the app, better hope it wants to show you, your account if not forget about it. Then you try and call Ad and d get their foreign customer service agency and usually they can't help you. So I don't know its enough to make me want a prepaid.
