I would like to sign up for unlimited data for my gigabit internet plan and keep using my own modem and router. When I try to sign up through this link http://xfinity.com/buy/plan/checkout/XFINUDAT I am taken to a page that says, "Temporarily unavailable. The product you’re interested in isn’t available for purchase at this time." How do I upgrade to unlimited data and keep my own modem and router? Thank you!
