In India, the pool of few private players and government agencies have been battling out since many years to attract the right share of market and provide quality service pan India. Private players such as Airtel, Vodafone, Idea Cellular and government agencies such as state owned BSNL have been competing closely to cater to the growing subscriber base, both voice and data. India has seen significant growth in its internet subscriber’s numbers with the figures growing exponentially year by year (Vamsi, 2016). The growth of 3G services and the launch of 4G recently by incumbents has exposed the country to high speed internet and better voice quality. However, still a large share of people are 2G prepaid users (kaushik, 2016) who prefer these high speed services only if provided at cheap cost. Riding on this wave to provide high quality voice call and data service, 'Reliance Jio' - a 4G venture of Mukesh Ambani, the chairman, managing director and largest shareholder of the biggest Indian conglomerate, Reliance Industries Ltd, set the river on fire with its mobile services launched in September 2016. Its USP: lifetime of free calls, charges only for either voice or data services, affordable internet tariffs at high speeds covering both rural and urban market. Overall, Ambani’s speech (Online, 2016) can be broadly categorised as - Push to Digital India movement by increasing the subscriber base and extending its services to rural India, provide high speed data connectivity and provide impetus to the growing data subscriber base.
