The Cellular Operators Association of India (COAI) has released some interesting data about the Indian GSM mobile subscriber base, and how various operators are faring. The total GSM subscriber base increased by 1.95 per cent in the month of April with 11.11 million new subscribers – taking the total up to a nice and massive 580.67 million. April’s growth figures are much lower than the first three months of 2011, which saw 13-15 million new subscribers each, and, quite a bit lower than monthly figures over the past year.
