In contrast to regular subscriptions, which get activated automatically, prepaid plans such as offline sales are delivered by activation keys to be entered manually inside your online account management.
The time frame to enter an activation code varies in respect to the type of the included package:
- No expiration date have CyberGhost VPN activation keys, purchased offline or with Bitcoins. These activation keys for Premium and Premium Plus subscriptions usually never expire and therefore don't have to be entered in a certain time period
- Different expiration dates have promotional activation keys. Promotional keys, for example of campaigns made by CyberGhost in cooperation with online and offline publications, as well as occasional Special Editions (e.g. special sales) must be activated within a specified time frame to avoid expiration, usually a few months after publication. Details for the last possible day of activation you can find in the liner notes.
