This paper examines the effect telecommunications infrastructure has on the growth of the Indian economy, emphasising the role that telecommunication usage and tools play on the GDP per capita and other economic parameters. It accesses information from different organisations, including the Telecom Regulatory Authority of India and UDISE+, to study the links between wireless and wireline users, user density, and school digital access and their impact on economic indicators. With advanced econometrics models, i.e. OLS regression, correlation analysis, random forests, step-wise regression, granger analysis, adfuller, and others, predictable solid relationships and directional relationships are proved to exist between the telecommunications background and GDP growth variable. The study results indicate that in India, there is a strong correlation between internet access in schools and wireless internet users. Moreover, it proposes policies to catalyse economic growth and digital adoption in India. It is a resource that policymakers can leverage to make the right decisions in harnessing the power of ICT for economic development
