US carriers have many protections in place that trigger when malicious third parties attempt to scam one of their customers. Today, AT&Tintroduced an extra layer of protection for online accounts that’s supposed to prevent key account changes.Wireless Account Lock is a new security feature offered by AT&T, which disables several key account changes such as billing updates or wireless number transfers. The security feature can be enabled from the new toggle button in your phone’s myAT&T app for postpaid consumer wireless accounts.

1. Open the myAT&T app. Sign in, if asked.
2. Select Services (second tab at the bottom).
3. Choose Mobile Security, then scroll to and select Wireless Account Lock.
4. Scroll to and select Continue.
5. Choose the account that you want to lock or unlock.
6. Swipe to lock or unlock the account.

It’s important to mention that Wireless Account Lock can be managed on the myAT&T app by the account owner and those who are given secondary online access by the account owner to co-manage the account.
