Sorry guys. Just need some help regarding iphone. My Aunt just bought new iphone yesterday in US. So the time she fly back here she still can receive call, but after she touch some setting, it can't receive any call at all. Both of her friends still can receive call. The Iphone is already been hack, but no sure which crack she use. But most properly i think she did turn some setting wrong that make it wont receive any call. Any help??? btw she use Maxis line.

Your help are highly appreciated
