I reatart my iPhone 5s. when it turns on it says “Sim not valid” how can I fix this. ps. My iPhone is GPP Unlocked
I think my Gpp iPhone got updated and now it can’t read my sim card. How can I fix this?
Do you know which carrier it is locked to? If so, you can contact that carrier and if you are eligible the carrier can assist you.
If you do not know, Apple Support can tell you which what the activation policy is on the phone but will not unlock it for you since that is a carrier issue.
