The Indian telecom sector has experienced high growth rates in recent years, with over 60 lakh new customers added each month. Tariffs have been drastically reduced, bringing world-class services to more accessible prices. Major services include fixed and mobile networks using technologies like copper, fiber optics, GSM, and CDMA. Key government initiatives opening the sector to private players and setting policies have driven expansion. Major players now include Bharti Airtel, Reliance Communications, Vodafone Essar, BSNL, and Idea Cellular, with intense competition among them.
