The document summarizes the telecom sector in India. It states that India has the second largest telecom market in the world. As of April 2016, there were over 1 billion mobile subscribers in India, with urban areas having higher teledensity than rural areas. The sector contributes significantly to India's GDP. The market has grown due to liberal government policies and the sector is expected to generate millions of jobs. The entry of Reliance Jio in 2016 with cheap 4G plans disrupted the market, gaining over 35 million subscribers quickly and forcing other operators to lower prices. However, Jio also faced issues like call drops due to actions of other operators, which led to regulatory interventions. A large spectrum auction was held in 2016.
