Has anyone experienced any problems with your phones not receiving phone calls? I've had, on more than one occasion, where people are trying to call me and it doesn't go through. My phone never rings but the person told me that it rang 3 times and went to voicemail. Is that Galaxy build problem or is that a T-Mobile problem? If there isn't an easy fix, I'm gonna call Customer Care and see if I can get the phone swapped for something else...
