A couple of years ago I saw a chart that showed the demand for revenue from 3G systems rising steadily over the next five years as the networks were rolled out and put into operation. What it also showed was the cost of a voice call on a 3G network falling steeply, and the expected revenue from voice forming an ever smaller component of the revenue total over the same period. The clear implication was that data and other services would have to be found to make up the difference. It pretty soon became obvious that the demand for those data services and the price we are prepared to pay for them are both pretty small. Now the other shoe drops.
