Buenos Aires has four major providers: Claro, Personal, Movistar, and Nextel.

I think the economics here might be a little different (aside from possible collusion between the operators) because such a large fraction of the population uses only SMS. If the providers have to put up new cell towers to provide SMS to an area, the economics are a little different.

Argentina in 2003 had just collapsed. Things cost three times as much here now, or more. On the plus side, that means the taxi drivers can afford electronics and other imports.

Interesting. These people who use only SMS, do they never use their phones to make voice calls -- or do you mean only SMS and voice?

They never (or almost never) use their phones to make voice calls. I hardly make voice calls myself.
