iPhone 6s needs to be unlocked
I have an old ATT iPhone 6s that I have not used for years that I want to get unlocked. I am no longer with ATT. I tried the unlock request but get an email that it can’t be completed because “we’re missing some information “. I tried calling the help number and they weren’t able to do anything since they couldn’t pull up my account since it’s so old. They told me to go to an ATT store and that they would be able to help me but they also were not able to help. I have no idea what to do now since I can’t get help through the request form, over the phone or in person!?! Any suggestions?
