You'll need to get it activated for service.

Use their Xfinity App;

user_rpvk41 We are here if you need assistance adding it to the account, but you should be able to get this done through the "devices" tab in the Xfinity app or website to get it added to your account as well. We are happy to assist though if you need us!😀
