Yes. Brazil privatized it almost all of its national telco infra in the mid-90's. We went from being a country where you'd wait years to get a landline installed to one of ubiquitous internet and cellphone coverage in a very short time-frame. Prices have gone down consistently and the companies are continuously investing in improving the infrastructure. The important thing about Brazilian privatization was that there was forced competition. Every major metro region had two have at least two different buyers and they had to compete. This led to ~8 big groups bidding for different regions in the whole country. Nowadays the restrictions on the regions were lifted and some consolidation came up, but overall the whole country still has every region with at least 3-4 different companies competing for the market.
