We always charge the credit card that was lastly added in the Control Center. If you wish to add a new card, you have two options:
If your subscription has already expired, you can create a new subscription by logging in to the Control Center > Manage > Locations > click on name > SUBSCRIBE and pay with the new card.
In case you wish to change the credit card BEFORE the subscription expires you can go to Tools > Wi-Fi Shop, choose Global, and choose “Add a NEW Credit Card” product. You need to pay with a NEW credit card (which has never been used before in the Control Center). We charge $2 USD for initial authorization.
Other than that you can contact us any time to remove a specific card from our system.
