You may have noticed your proxy subscription has an option called "Auto top-up".

This feature allows a user to automatically renew (top-up) their package once it runs out of remaining data. We will try to bill your remaining website balance to renew your subscription.

If there is enough available balance, we will automatically renew your package: that means the package will be unavailable for 15 minutes as it needs activation, for now.

In case you don't have enough balance you will not be billed and your subscription won't be automatically renewed. We won't try to automatically renew your subscription if we fail doing so once, so make sure you always have balance when intending to use this feature.

You can tell which packages have auto top-up enabled by a green "renew" icon in the main dashboard page:
