Any help will be appreciated.'Īccording to some iPhone users, the SIM card unsupported issue happens now and then.
The phone returns to the Hello screen after Apple Tech 752 Silver 5.5 bypass procedure. I have tried the sliver 5.5 iPhone bypass method, but it didn't work. Is it possible to skip the SIM NOT SUPPORTED screen on iPhone 4? The phone is not iCloud locked, but it just needs SIM activation.
