Interesting statistics about mobile phone usage:
In the UK, the number of outgoing voice calls made to the number of text messages is 0.6:1; in South Africa as a whole the the ratio is 3:1 for pre-pay phones; and in rural communities the average ratio is 13:1. Text messages are cheaper than phone calls, so this data, looked at from a western perspective, seems surprising. However, when considered in the context of a community where a significant number of people are illiterate it is more understandable.

Illiteracy doesn’t seem to slow down the youth of today on MySpace. At least they seem to understand each other’s written output.
