Change credit card

user_y4kxa4, thank you for confirming. I see you have questions about the same thing, and I'll be glad to help. You will be able to update your payment methods online at any time using the Xfinity website or Xfinity App, which you can read about here: https://www.xfinity.com/support/articles/my-account-app-manage-stored-payments. This second link here: https://www.xfinity.com/support/articles/update-payment-information covers the same but for your mobile services. To do both, you'll have to log in to your account using your Xfnity ID and password. If you haven't created an online profile yet, you can follow this link to learn more here: https://www.xfinity.com/support/articles/create-xfinity-username.
