From a Market Asia Pacific article:

India appears to be at the forefront of the developing market for mobile phone (and data) services to young people, according to the Website mobic.com, an effort of The Mobile Internet Community (Norway).

A May 20, 2005 posting, using information provided by the Wireless World Forum, a research consultancy, says that the number of young people using mobile voice and data services in the Asia Pacific region will more than double from 71-million in 2004 to 151-million in 2007. This market segment will increase spending by US$3.3-billion for the years 2005 through 2007 to push total spending to US$43-billion in the region.

India’s mobile youth market will grow 300 percent from 2005 through 2007, from 8.3-million to 27.6-million people. This means India will account for 18.3 percent of this large and growing market.

India’s young people spent US$437-million on mobile telephone services in 2004. In 2005 they are likely to spend US$856-million. And by 2007 this expenditure will almost triple to $2.5-billion.

It is clear, also, that this vast interconnected population will create demand for other products of the information age, representing significant market opportunities.
