AT&T Launches Wireless Lock to Prevent SIM Swaps and Billing Hacks

Looking to keep your AT&T wireless account safe from unauthorized changes? AT&T just rolled out a handy new feature called Wireless Account Lock, and it’s free for postpaid customers.

This feature adds a simple yet powerful layer of protection by preventing major account changes—like billing info updates, device purchases, and SIM swaps—unless you manually unlock it first. You can find the toggle right in the myAT&T app on your phone.

Here’s how it works:

• Once enabled, if someone tries to transfer your phone number to a new device, add a line, or make billing changes, the account stays locked until you approve it.
• You can switch it on and off yourself at any time.
• Just note: if you share the account with family members, they’ll need your permission to unlock it to make changes.

AT&T is also bringing similar tools to its business and prepaid users. Business administrators can manage their locks through their online portals, while prepaid customers get a comparable feature via the same app.

Why does this matter? AT&T points out that many online account takeovers start with someone stealing your login—which they often get through fake emails, phishing scams, or password hacks. Adding this lock makes it a lot harder for crooks to mess with your wireless account, even if they somehow got your credentials .

The company also reminds everyone to use standard security habits: don’t share passwords or PINs, and look out for suspicious calls or texts. They note that AT&T will never ask you to disable this lock themselves—so don’t fall for any scam prompts.

In short: turning on Wireless Account Lock gives you peace of mind with just a tap in your app—a smart move in our always-online world.
