Phone number shows as "unknown" in settings, I need help
Okay, so my iPhone 4 is unlocked on iOs 5.0.1 and in the phone settings my number shows up as "unknown"
I thought it was a Sim card issue since my AT&T card that I use to activate the phone has no issue with showing the number.
When I used a T-Mobile micro sim, it didn't pop up. I got another sim from T-Mobile and it still didn't pop up.
I tried deactivating the phone, but that didn't work either.
I have service and everything but FaceTime and iMessage don't work.
Does anyone know of a possible fix?
