According to eT Forecasts's report, Cellular Subscriber Forecast By Country, the total number of cellular subscribers world wide was only 11 million in 1990 and among them 49 percent were in USA. From 1990-2005, cellular subscriber number grew by 187 fold to 2,065 million. But in this period share of US in the total number of subscribers fell below 10 percent. It is estimated that the subscriber base in USA would be increased from 202 million in 2005 to 293 million by 2010.The traditional telecom sector in USA has also increased considerably during 1990-2005.

The report also cautions that the subscriber growth in developed countries would be limited as the market has already reached at a saturation level. So machine-to-machine (M2M) communication where embedded wireless modems are used for data transmission is termed as one of the potential area of growth.
In the next decade the cellular industry will witness a dramatic change in its look and content.
