As we have to get an authorization from you for your new card, the only way to change the card used for payments is to cancel your current subscription and resubscribe with a new card.
Step 1 - Cancel current subscription:
Step 2 - Subscribe with a new card:
Please note: If you are using a credit/debit card for the payment, at the time of resubscribing, we'll charge you for a full month immediately, but you won't be charged again at the end of the current period. We have to do this charge to get the authorization for your card. You can wait until your current prepaid period is up to make the change, or do it immediately, it's up to you.
If you are using PayPal for the payment, you will be charged at the end of the current period.
