Customer-owned modem activation WITHOUT using a phone or an app

What is the procedure for registering a customer purchased and owned cable modem without using a smartphone in any way ?  I do not own a smartphone, and without a working, registered and activated modem, I have NO internet connectivity.  Does Xfinity still use a "walled garden" website (ie. the old style "xfinity.com/activate" site) as an option to activate and register a new customer owned modem ?

The concern is not "Community Knowledge Base" related............ Topic moved here to the proper help section, and for greater exposure to Comcast corporate employees (The Digital Care Team) for assistance.

jwjojr For an owned modem, an agent would need to gather the device make/model, and MAC address to add to our system, so we would technically be the ones to do the initial activation for an owned device. Once everything is in the system, you are able to troubleshoot the device on your end.

So, there are NO self-activation / new modem registration options that do not require the use of a smartphone or the app ?  Is there a dedicated service line to help with the task or does it require a call to 1-800-XFINITY ?

Good morning and happy Tuesday @jwjojr, This is a great question. Without a smartphone device for the XFINITY App you can definitely call in at 800XFINITY (800-934-6489). A second option is logging into the Xfinity website with your primary username and password at https://www.xfinity.com/overview and use the Xfinity assistant to activate your modem. 

A third option is having our team add it via direct message by sending us your name address to begin.

Here's the detailed steps to direct message us:
• Click "Sign In" if necessary
• Click the "Direct Message” icon (upper right corner of this page)
• Click the "New message" (pencil and paper) icon
• Type "Xfinity Support" in the to line and select "Xfinity Support" from the drop-down list
• Type your message in the text area near the bottom of the window
• Press Enter to send your message.
