Currently only offered in states of Puebla and Leon, in Mexico.
But looks like it's offered everywhere in the U.S. for $19.95/month, with the first 6 months being $9.95. And the one being offered in the U.S. says they have over 50 Mexican channels, whereas the one in Mexico has about half that. Mostly crappy channels that are already available via MASTV, for about ten bucks a month. I subscribe to them, in fact, for two years now, just to get the add-on package of HBO, Cinemax, MovieCity, CineCanal, FilmZone, etc.
I pay $280 pesos a month total, which is $22 a month U.S. kind-of a deal, when you think about it: I think I was paying that much JUST to get HBO when I lived in the U.S.
