The wireless phone subscriber base in India has already crossed the 100 mln mark and will more than double to 265.2 mln by 2010, reports In-Stat. ARPU in India is one of the lowest in the world and is expected to decline further to US$5.60 by 2010. The prime reason for the decline in ARPU is the downward trend in tariff structure for subscribers due to intense competition. The leading operators are Bharti Airtel, BSNL, Reliance, Hutchison, and Idea Cellular. Combined, these players accounted for about 84% of the subscriber base in 2005.
