What's SIM protection?

SIM Protection is a free feature that adds additional security to your account to protect you from the most common instances of SIM swap fraud. You can prevent SIM changes on individual lines or the whole account! SIM protection does not prevent eSIM transfer on Apple devices, due to the extensive security steps already included in that process. 

Who can add it?

• SIM Protection is available to all T-Mobile Postpaid. 
• You must be registered as the Primary Account Holder or have Authorized User Access permissions.
• Not available to T-Mobile for Business, T-Mobile Prepaid, or Metro by T-Mobile.

Turn SIM protection on or off

Log in to your T-Mobile account to turn SIM protection on or off. You can find the settings under My account > Profile > Privacy and Notification.
