Can you pay your xfinity mobile bill at xfinity store !?

As an employee no xfinity mobile is card only. The kiosk will let you pay for internet tv etc but Not mobile

Yes, you can pay your bill at the kiosks in back.

Pretty sure the mobile bill is only payable through the app or on the phone..

You can pay at the store but you have to do it through a Representative.

No. Xfinity Mobile can only be paid through automatic payments on your bill due date with the card you have on file for your account.
