We all know how popular and widespread mobile phones have become in Africa, Tanzania in particular. However innovative mobile services have yet to catch on. This Fast Company article http://tiny.cc/JxSHE describes one of the many ways NGOs in Tanzania and across Africa are leveraging mobile services to solve day to day challenges with direct positive impact.
Note however, that these are foreign companies bringing in solutions from outside. I don’t see how the NGOs can’t employ Tanzanian developers and even more surprising is that local firms aren’t capturing this market.
