If you have Unlimited Elite or Extra, you'll enjoy advanced mobile security features at no extra charge. You'll also get AT&T ActiveArmorSM and its key network security add-ons. These add-ons include automatic fraud call blocking and suspected spam risk alerts.

  • If you're on a select unlimited plan with AT&T Wireless, be on the lookout for a text explaining how to activate your advanced mobile security at no cost.
  • If you’re paying for this service through your AT&T bill, you can decide which features are important to you. Then you can choose to:
    • Change to the advanced mobile security for free, and discontinue your Call Protect Plus features (Caller ID, Reverse Number Lookup, and Nuisance Call Controls). To make the change, sign in to myAT&T and remove the Mobile Security & Call Protect app. Then choose Mobile Security Plus for Unlimited Plans.
    • Keep paying $3.99 per month for AT&T Mobile Security and Call Protect Plus and enjoy all the advanced features of both apps.
  • If you subscribed thru iTunes or the Google Play Store, pay $3.99 per month for the service, and want to change to free Mobile Security Plus features, you'll have to cancel your subscription in the app store. After your subscription bill period ends, you can select AT&T Mobile Security Plus for Unlimited plans within myAT&T.
