Granted, I really do need to get out and see the world. But I had thought that 'burner' cell phones were quite ubiquitous in the developing world?
For this reason, countries like Ecuador, Guatemala, etc. Have cell phone rates higher than developed countries like Australia and the US. http://en.wikipedia.org/wiki/List_of_countries_by_number_of_...
Developing countries don't skip technologies out of a desire for hopscotch or something. They skip wired tech because copper wires are expensive, their expense doesn't go down over time in contrast with the increasing sophistication of chips. Conventional phone lines and electrical power are both wired tech. Thus both are harder in third world conditions.
