Tim You can keep one of your already existing sub-accounts / cards. When you try to downgrade to Easy Bank and you have too many sub-accounts etc., the app will prompt you to delete them. Also, you can actually have more than 1 card on Easy Bank, but there's just an additional monthly price then. So if you want to avoid this charge when you change to Easy Bank, just make sure to block all your cards except one and then downgrade to Easy Bank.
If you're unsure about the pricing, you can find out more by going to bunq.com and especially by checking out the Pricing Sheet for details.
