Every time I try to call my girlfriend, She has US Cellular, it goes straight to busy. I can text her, she can call me, she can get calls from other people, i can call other people, but i CANNOT call her. I've done just about all i can do besides loading my recovery. The thing is i dont know if its a problem on her side or mine, sprint tells me to have her call us cellular, us cellular tells me to call sprint. wtf is goin on?
