Need something achievable for an extremely tech illiterate person on iOS. I got told about this after they are already gone and have no access to the device, but am asked to solve the problem.
EDIT: (SOLVED) Signal was super easy, works awesome, and was easy even for my mom to figure out on her own. Thanks
If they do not have cell service, they won’t be able to set up Signal, or any other service that requires a phone number (they won’t be able to receive the text message that verifies they own the number).
