A subscription purchased in the Avast Mobile Security app is automatically activated on the Android device you use to make the purchase. A subscription purchased through another Avast sales channel, such as the Avast Store or an offer within another Avast product, needs to be manually activated using a valid activation code (sometimes called a subscription code or voucher code). If you want to use your Avast Mobile Security subscription on another device, you also need to manually activate it. The number of devices you can activate depends on the subscription you purchased.
Troubleshoot activation issues
In some cases, subscription synchronization may take up to 24 hours after purchase. If your subscription is still not active after this time, refer to the following article:
- Avast Mobile Security 6.x for Android
- Google Android 5.0 (Lollipop, API 21) or higher
