Bharti Airtel is India's largest telecommunications company. It launched cellular services under the Airtel brand in 1995. Over the years, it expanded its offerings and acquired other companies. Today, Airtel offers wireless and fixed line services, DTH, and smartphones. It has over 280 million customers across India and international markets. However, Airtel faces stiff competition and needs to improve its customer service to retain users in a rapidly changing telecom industry.
