Hi @Julio13
Thanks for coming to the community.
You can change your direct debit details by logging in to your EE account through the website.
There is a step by step guide on how to do this on our Change your EE Direct Debit date or details page.
This would just apply for an airtime account, so if you are paying for a device on Flex Pay, please give us a call and our guides can update the payment details for you.
