Even though Telmex (his landline company) was acquired from the state, and therefore was a monopoly from the start, Slim faced a monopoly by Iusacell on the wireless phone industry, which he managed to break and manage to get Telcel (his wireless company) to become a monopoly basically by making people want to switch.
Slim's story includes several investments on different industries, including specialty shops (Sanborn's) which he has managed to completely turn around from near-bankrupcy to huge commercial success.
I am not making a claim that his wealth from Telmex didn't contribute to his success, but implying he just managed to get where he is because Mexico's regulatory bodies are useless is a huge understatement to his ability in an industry where several key players (Like AT&T, Nextel, Telefonica Movistar, and others have failed).
You can't think of any ways Telmex could leverage its landline monopoly into advantages in the wireless sector? Or use an existing monopoly to prevent new competitors from gaining traction, no matter how well-funded?
Telmex charges exorbitant fees for any call that needs to connect to one of their customers. Given that they own 90% of the market, it's impossible to run a telephone company without letting your customers call Telmex customers. If you have to pay Telmex's fees, there's no way your prices to customers will be competitive.
