Bharti Airtel has shut down its 3G network in Madhya Pradesh and Chhattisgarh.

However, the telco will continue to provide 2G services in the region to serve the customers on feature phones.

As per the telco, it has re-farmed spectrum in the 2100 MHz band which was being used for 3G services, to further strengthen its 4G Network. Airtel has now deployed L2100 technology on 4G to complement its existing 4G services.

All 3G customers have been notified and requested to upgrade their handsets/SIMs and customers who are yet to upgrade their handsets/SIMs will continue to get access to high quality voice services, the telco said.

In Madhya Pradesh and Chhattisgarh, Airtel uses a formidable spectrum bank – 2300 MHz (TD LTE), 2100 MHz (FD LTE) and 1800 MHz (FD LTE) to offer 4G services to customers.
