Hey @user_4gk621 , Thank you for visiting our official Xfinity Forums Community support page. We greatly appreciate you taking the time to reach out regarding your final bill. When you cancel all your Xfinity Mobile lines of service, you lose access to the My Account sections of xfinitymobile.com and the Xfinity Mobile Service Card within the Xfinity app. If there is a card on file it will charge the remaining balance due automatically since Xfinity Mobile billing is auto payments. 

@user_4gk621 It should allow you to submit a payment for any final balances. Are you using the website, or the Xfinity app? 

i have tried both on multiple occasions and it just defaults back to the ''call this number'' you dont have any services

Hi @user_4gk621 and thank you for the additional details. We apologize this is happening to you. It’s definitely frustrating.

We can help get this resolved. Let us take a closer look with you and figure out what’s preventing you from logging in to make the payment.
