How do I update my Xfinity Mobile payment information? (Answered)

***Updated 6/15/2026***

We keep things simple by having you keep one credit or debit card on file for all your Xfinity Mobile payments. Protecting you and your information is a top priority for us. Because of that, an agent can’t update your payment information for you over the phone or through chat. You can easily update your card from any device, at any time through the Xfinity Mobile website or the Xfinity app.

Change your card on file

Xfinity Mobile website

1. Go to your Xfinity Mobile account and login using the Primary or Manager’s Xfinity ID.
2. Select Settings > Payment Method > Update Card.
   • You’ll need to confirm your identity by entering a six-digit code sent to a trusted contact method before proceeding.
3. Once you’ve updated the information, select Save.

Xfinity app

1. Go to the Xfinity app on your phone and login using the Primary or Manager’s Xfinity ID.
2. Click the Account tab in the lower-right corner.
3. Select the Xfinity Mobile Billing Card and then select Bill Details.
4. Select autopay method.
   
   • You’ll need to confirm your identity by entering a six-digit code sent to a trusted contact method before proceeding. 
5. Once you’ve updated the information, select Save.

When you update your card on file, any outstanding balances as well as the automatic payments for your Xfinity Mobile bill will be charged to the new card.
