Greetings, @jhhillis! I appreciate you taking the time to reach out to us here on the forums. I hope you are having an amazing day! The xFi advantage has recently been rebranded to xFi complete. If you are rent your modem from Comcast it would include the cost of the modem and unlimited data. If you would like me to get this added to your account, I certainly can! Feel free to send me a PM with your first and last name so I may further assist you!
