and lock the SIM card. Its very easy and was mandated that all cell phone companies provide this some time in 2024 (but NONE of the companies notified their customers). It was very odd and I discovered the feature by accident.
At the bottom of the main page in the app go into the 4 little boxes to the right of the home icon. It will take you to mobile security. You look for wireless account lock. Follow the prompts and swipe to lock. Now no one can steal your sim and hack your phone. They cant go into a AT&T store and sweet talk the worker into accessing your information claiming to be you.
You also will be limited (cant search for a new phone or change your plan) but then you just unlock it to perform those tasks and then relock it.
FYI recently that feature wasnt functioning properly. It said it was locked for me but when you went into the security page it said you had to be on a phone associated with the account to do anything. I was!! There were lots of complaints on the app. It appears to be resolved now and I locked mine again last week but from now on Im checking it more often.
Good to hear your banker is advocating for you!!
