The entity in charge of regulating this is probably the SUBTEL,(Subsecretaría de Telecomunicaciones, subsecretary of telecommunications perhaps is the translation?). I don't know if you have any idea about politics in Chile, but we have several political parties over there, not only two. Yeah, there are like 3 or 4 that are bigger and with more power than the others, but they don't get to bend government entities the same way political parties in the US do. So in a way, by being more political (more parties), they are less political (the power is more spread). I don't know if that makes sense, but it sounds pretty haha.
Chile doesn't have states like the US. The main divisions are regions. They have their own governmental entities but they're all controlled by the central ones in Santiago, the capital. So regions don't get to do whatever they want either, meaning that if the government creates a law, all the rest of the regions have to follow, and individual regions can't make their own laws.
I hope that helped somewhat to understand a bit how Chile works. Of course, the real question is if the SUBTEL is going to care enough to reinforce the law in all its extent. That's a completely different deal.
