Airtel is the second largest mobile operator in Asia-Pacific by subscriber base, operating in 20 countries in South Asia and Africa. It was the first to provide 4G service in India. The CEO of Airtel is Gopal Vittal, who has been CEO since 2013. Airtel began in 1992 when Sunil Mittal won a bid to set up a cellular network in Delhi and has grown to over 66 million customers across its mobile, broadband, and DTH services in India and Africa. It has a large workforce and focus on telecom but depends heavily on the domestic market and faces competition from other operators.
