Reliance Industries Limited (RIL) acquired a 96% stake in Infotel Broadband Services Limited (IBSL) in 2010, later renaming it Reliance Jio Infocomm Limited (RJIL) in 2013. Jio analyzed the untapped potential of India's telecom sector after demonetization and gained customers by offering free data and services, increasing GDP by 1.38%. While Jio leads in technology like VoLTE and plans to offer 5G, it faces challenges from competitors and limitations of existing 3G networks, while seeking to merge services and address issues like reduced speeds and battery drain from its 4G services.
