When I was in France, free.fr offered unlimited telephone (with mostly free worldwide calling), TV, and internet for 30 euros a month. As far as I have seen, it is the best system in the world.
Japan is about twice that expensive, but offers similar service (except the cheap telephone. Telephone service there is the worst of any industrialized nation, by far) along with fairly cheap fiber optic, all uncapped.
These are my principles. If you don't like them, I have others.
