When signing up for VyprVPN, we suggest using one of our accepted forms of payment. However, if you wish to use a prepaid or gift card, it is possible that it will not be accepted. This is usually due to limitations from the provider of the card. Specifically whether or not they allow recurring payments. To determine whether or not your prepaid or gift card can be used, you will want to contact the provider to confirm recurring payments are allowed.
