Codes can be activated any time as long as you have a valid HotSpot FREE subscription (so codes that you get in the first month don’t expire, they can be used f.e. 6 months later). If you chose the Pay As You Go model, you can use the available credits from 1 year after the LAST Pay As You Go purchase (so you can extend the expiration to another 12 months if you buy again).
