You cannot use a EuroDOCSIS Modem on TWC. As long as the SB5101 is from the US, it'll work. I don't think the U in the SB5101U indicates it's from the US, it's just a different version of the SB5101.
Technically, you can use any DOCSIS2/3 modem with TWC. As long as you can get the customer service rep to enter the MAC address, it'll work.
As for the bill, I believe they'll prorate even the modem fee.
