🦅 The additional monthly costs for cards that aren't included in your plan you can find in the pricing document: https://www.bunq.com/policies/pricing If you switch to a plan where you cannot use a card at all, then they won't be usable anymore. But if you have multiple cards and switch to for example Easy Bank, which has only 1 card included, you can still use other cards. They will incur additional monthly fees as long as they're still active.
