What does it say when you update the info?

Hi @Buknbun 

What’s the error you get when you try to update the credit card details?

Have you tried removing the old one completely and setting up the new one?

Please note that it may take up to one bill cycle for the pre-authorized payment to become active, so you might need to make the payment manually if not withdrawn automatically before the due date: https://www.koodomobile.com/en/help/setting-pre-authorized-payments
