Unable to activate iPhone 7 IOS 15.8
Attempting to download and activate with 15.8.2 and I receive an error "an update is required to use cellular data on your phone". None of the perviously published remedies provided in this Support Community string have proven helpful. I have tried reseating the SIM chip, using another working chip, resetting the phone network, resetting the phone completely, factory resetting the phone. The only solution I have not attempted yet is jail breaking the phone which seems to all over YouTube as THE solution. Can anyone help? Apple? anyone?? Thank you in advance for any advice you may have.
