Activating Avast Mobile Security

 

Avast Mobile Security is available as both a free and paid app. After you install the free version of the app, you may need to activate it. A subscription purchased via Google Play Store or the App Store activates automatically on the device you use to make the purchase. If you purchase your subscription through another Avast sales channel, such as the Avast Store, you need to manually activate the app using a valid activation code or your Avast Account.

If you purchased a subscription bundle such as Avast Mobile Ultimate or Avast Cleanup Premium Plus in the Avast Cleanup application, your Avast Mobile Security application will activate automatically.
This article is valid for activation of both Avast Mobile Security Premium and Avast Mobile Security Ultimate for iOS.
