HW unlocked iPhone rejecting calls with my Carrier!!! Help!
I did the hardware unlock step by step, and it worked but I can't receive calls, I can call out with the iPhone, but if someone calls me it gives busy signal, and if someone calls me while I'm in a call I get call waiting message and it drops, as if it's rejecting the call. surprisingly I tried another carrier's sim and it worked. but I don't want to change the carrier since I'll lose my number.
I restored, and reactivated but still the same! what could be wrong with this carrier?
Any help appreciated
iPhone 8GB 1.02
call in/out no/ok
