I just found another statistic. Mobile networks cover
roughly 80-90% of the
worlds population.
For them, using that mobile network is probably the most cost effective
solution. For the rest, giving them enough of an education to have the
means to come live with the rest of us, is probably the most cost effective
solution.
Those are basic mobile phone networks, not internet phones. I don't
think voice calls and SMS messages are going to be much help.
