That would be highly unlikely to have 3 Korean channels as a standard in any package. Unless maybe you live in a huge headend area that's predominantly Korean.
As far as I know, the only Korean channel that comes standard with any provider's service is KBS World with Dish Network. It comes with anything above the stripped-down, "Family Tier". (I know this because I specifically wanted it myself.)
I could be wrong - someone else may carry one - but I still would doubt if it would be 3 channels. You normally have to subscribe to the "Korean Package" specifically, to get that many (or more). I think with Dish it's something like 25 or 30 bucks per month extra for a handful of channels. (And we though WE were overpaying so much for all the English-language channels!)
