Bharti Airtel Ltd.

Bharti Airtel will invest Rs 25,000 crore in expanding and strengthening its 4G network during the ongoing fiscal year instead of Rs 20,000 crore announced earlier. The company is likely to shut down its 3G network in 3-4 years and refarm the spectrum linked with it for 4G services.

Bharti Airtel is a leading global telecommunications company with operations across Asia and Africa.
