A subscription purchased in the Avast SecureLine VPN 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 SecureLine VPN subscription on another device, you also need to manually activate it. The number of devices you can activate depends on the subscription you purchased.
