Hi guys i'm from the Philippines but I will be in LA this month and I have been thinking about buying iphone 5c in AT&T? And do you have any idea how much is it? No plan or anything just an iphone 5c with a micro sim holder. And i really need to know if WILL IT WORK? And what are the prices? According to the GB

Yes, of course it will work. Unlocked phones work anywhere around the world.
