Yahoo India, a subsidiary of Yahoo! Inc., will concentrate on wireless data services as it expects a large growth in the sector due to rise in mobile phone users in the country.

"Even on a conservative outlook, we expect the wireless data services market to grow at around 100 per cent in line with this mobile telephony sector in India," Yahoo India country manager Neville Taraporewala told PTI on Friday.

The Internet portal, which had already begun offering PC-to- mobile based services in the country, including SMS, downloadable ringtones, picture messages and logos among others, would cash in on the exponential growth, he said.

Yahoo India has revenue sharing agreements with most of the GSM service providers, except Bharat Sanchar Nigam Ltd and BPL, he said, adding it would soon be signing deals with these players too.

The company's total subscriber base for wireless data operations rose to over one crore (1 billion) in 2003, compared to 40 lakh (4 million) posted a year ago, he said, adding, "an evolution of data from Internet and PC-based systems, to handheld systems like mobile phones is being experienced in India".

On the revenue expected from the mobile data operations, Taraporewala said the company expects to post a "double digit" figure this year.
