I received my new (gently used) iPhone from Public Mobility. I put the sim card in. I got an email saying the card is now active. The phone shows No Service in the top left corner. When I set up the phone it takes me to the sign in for apple id and password. When entered it I get a message that says ... "Software update required. Update this iPhone to the latest version of iOS to sign in. you can do this in Settings once you have finished setting up this iPhone." It will not allow me to go to settings. I can't go any further. HELP.
@Choklit2264 I wonder if a Hard Reset of the device would help. anything to back up first?
"Press and quickly release the volume up button, press and quickly release the volume down button, then press and hold the side button. When the Apple logo appears, release the button."
If still issues and if others cannot provide other solutions to help, contact CSA.
Public Mobile Representatives customer support agents (CSA) can be contacted by either two methods, found here:
Then do a full reset.
Have iTunes on a computer and link phone to computer with a lightning cable and do a reset.
Have iTunes on a computer and link phone to computer with a lightning cable and do a software iOS upgrade.
Follow the DFU process <== google it for your iPhone model.
DFU....you are probably thinking some rotten stuff what the acronym means...it means.... Device Firm Upgrade
