In Europe, for example, there is a mobile phone subscription for every 0.8 people. Or thirteen mobiles for every 10 people, which might be an easier number to envisage. Once you take away the very young and the very old from the equation, that means a very large number of people with either two phones, or a data dongle, or a GPS-system that requires a SIM, or maybe tablet computers.
In Africa, on the other hand, there’s one mobile subscription for every 2.4 people. Or four phones for every ten people. As you can imagine, the numbers are a lot lower than that in poorer, rural regions.
