Error Message locked SIM card & Invalid SIM
Purchased a new unlocked iPhone SE 128GB to replace a SE 64GB. Moved SIM over and completed activation with Sprint than began getting this message “The SIM card has locked. Please power cycle the device If problem persists contact Customer Service” followed minutes by “Invalid SIM”.
Did a reboot, a reset, and carrier updates and it still occurs.
Should I just return the phone or is there a reason behind this issue that can be fixed?
