I own my own modem and router, and do not wish to use an xFi device. Trying to purchase the $30 Unlimited data add-on gets me to a "Temporarily Unavailable" page, which by reports here has been that way for quite some time. Seems like the only way people are able to purchase this option is by posting here and getting a direct line to a support agent to do it manually, so that's what I'm doing.
Hello, @rynomad and thank you for reaching out to us on Xfinity Forums! I would be happy to assist you with the unlimited data add-on on my end.
