Just curious, but is it possible to give the costs for comparable contracts in other countries, too?
A phone isn't included in the contract (the contract can be stopped anytime) but my provider (Free) also sells phones on credit, say an iPhone 5s for 49€ one time payment and then 16€/month over 24 months.
That makes a close equivalent of the US contract, for 38€/month or about 50$/month.
Also, in reality I'm paying 4€/month for this contract for the first 12 months because of a promotion back in June.
