The telecom sector in India has experienced significant changes in recent years. The entry of Reliance Jio in 2016 disrupted the market and forced established players like Bharti Airtel, Vodafone and BSNL to face tough competition. In response, some companies collaborated - Idea and Vodafone merged to become Vodafone Idea. The telecom industry is now the fastest growing sector in the country, contributing greatly to GDP and job growth. Continuous innovation is driving the industry forward to become more advanced and reliable.
