ComCast Dedicated CableCard Activation Phone #
They actually answer the phone "Cable Card Activation"
It was offshore, and the rep wasn't sure when they were open, but said 7 days 7AM - 1AM Eastern Time. FYI.....Super busy on Saturdays.
My S3 (2 M-Cards) were recognized with no problem, and just have to wait 1 hr or so before re-running channel set-up.
She said if any problems to call state-side tech support at 800-934-6489
