Less than 45 percent of the area of Tanzania is covered by any form of cell phone reception. Telecom providers target high-population areas first, so the percentage of the population covered by the cell phone signal is 83 percent. But the problem is that the remaining 17 percent of the population, or 9.2 million people, is spread over 55 percent of the country—meaning the density of potential users is low. Especially because rural populations tend to be poorer than city dwellers, the revenue generated per cell tower may be too low to justify rollout.
