I'm actually speaking from experience. I live in NYC and last year during Sandy we ran into many of the problems you describe. Business and Individuals in areas that still had power were setting out extension cords and power strips for people to recharge their phones. Mobile generators can be used for the same purpose (and growing up in Texas it was my experience that most people in isolated rural areas either already have a portable generator or know someone close by that does).
The situation you described in Rio and Sao Paulo is not unique to cell phones. POTs systems have a limit on how many calls they can support as well, the dreaded "all circuits are busy message" here in the states. The reason POTs lines are less susceptible to that now is that fewer people are using them so it doesn't happen as often. A common solution to this is to tell people just to text instead of making calls, that helps reduce the load on the cellular infrastructure.
