India’s mobile industry is set to consolidate in three years, forcing at least half of the industry’s 12 operators to sell or go out of business, according to Manoj Kohli, chief executive of Bharti Airtel, the country’s biggest wireless operator.

He also expected international telecoms companies to continue to expand into “the world’s most competitive market”, which has about a dozen players, despite the entry of three foreign groups in the last few months.
