Network seems to be locked after upgrade to iOS 12
My 6S stopped working after upgrading to iOS 12.
Currently, it will operate normally WITHOUT the SIM card inserted. But when a SIM card is inserted, a notification pops said “Activation Required”. Tap “Dismiss”, and it will continue to “Hello” screen (like the first time it turned on), a moment later it’ll switch to home screen, without any cell reception, and pops another “Activation Required”, and repeat the whole thing mentioned.
I tried reverting to iOS 11.4, but as I write this, it still no result.
Es esta una buena pregunta?
