smyles If you have a Premium, Business or Joint subscription, it is just another payment card. But not if you take a Travel Card subscription. Then you only have the payment card and no bank account.
See https://www.bunq.com/assets/media/legal/en/20190606_terms_bunq_personal_EN.pdf at the bottom of page 5: "We also offer the bunq Travel Card membership, which is not a bunq bank account but simply just gives you the best card to travel the world! "
And the Free subscription where you did have a checking account (but not a single payment card) apparently cannot be taken out now.
