Unlock a U318AA phone from AT&T
my 98-year-old father's Windows phone can no longer be charged. I bought him one of the "senior citizen" phones but he cannot use it since he is used to touch screens and this phone uses arrow keys to make selections.
i received a U318AA phone from AT&T for due to the upgrade to 5G. I do not need to use that phone so i wanted to repurpose it for my father. Unfortunately, he does not use AT&T and does not want to change providers - at this age, he doesn't want to change anything (which is why i did not upgrade him from the Windows Phone in the first place).
I tried to unlock this phone but was not able to.
i get an error that says something like "It looks like your device is not an AT&T device". the phone has AT&T stamped on the back and i got it from AT&T
what can I do to unlock this phone so my father can use it?
