Spam calls are still getting through

Spam call blocking isn’t turned on automatically. Turn it on in the Calls tab of the app. Plus, you can view your call log and report callers there. You can change these settings at any time. Learn about the other free mobile security features

Keep in mind, the app may not detect all threats and may inadvertently block wanted calls. You can adjust the settings in app.

Why are my call logs missing or delayed?

If you can’t see recent call activity or other data doesn’t appear in the app right away, the app may still be syncing. While we strive to display info in real-time, some updates may take longer to appear.

You can check back later or try to force the sync by following these steps:

  1. Sign out of the app.
  2. Turn Wi-Fi® off.
  3. Reopen the app using the AT&T cellular network only.
  4. Check again for updated activity.

Safe Browsing stopped working

If another VPN or DNS profile is turned on for your phone, Safe Browsing1, 2 may be paused. To fix it:

  1. Go to the network settings for your phone.
  2. Check if your VPN profile is active and ActiveArmor is listed. If it’s not, you’ll need to turn it on in the Internet tab of the ActiveArmor app.
