From my traveling experience in Ghana I can say that mobile usage there is crazy big. Everybody has a phone, but almost always a really basic (partly broken) phone. So except for the richer audience, smartphone are almost non-existent.<p>This, however, does not mean that mobile internet is also non-existent. Although data reception is pretty much bound to larger cities/communities, it goes through the entire country. And sometimes I even had reception in the most desolate places.<p>But the most interesting thing was that phones are actually used for calling people. When you exchange numbers they just randomly start calling you to ask you how you are and whatnot.
