The erstwhile closed market policy was replaced by a more liberal form of economic policy. A whole new form of Indian Telecommunication policy was drafted to compliment the change effected in the economic policy of India. The amendment affected the new telecommunication policy of India made huge changes with respect to investments and entry of Foreign Direct Investments (FDI) and Foreign Institution Investors (FII) respectively, into the virgin Indian telecommunication market. This resulted entry of private, domestic and foreign telecommunication companies in India.

The economic contribution made by these newly formed telecommunication companies of India is really mentioned worthy and this industry witnessed highest growth after the Indian Information Technology industry.
