updated to a 1Phone 12 from an iPhone 7. Did the back up and switched the sins card from the 7 to the 12. iMessages won't work to non iPhone users. In settings there is a message that says activation failure. Do I need a new sim card?
Updated to an iPhone 12 from an iPhone 7. Did the back up and switched the sims card from the 7 to the 12. Registered with our carrier. But iMessages won't work to non iPhone users. In settings there is a message that says activation failure. Do I need a new sim card? Or how can I fix this?
