The best thing about airtel is internet service provider that they provides low ping for online gaming . airtel gives you 60-70 ping which is very good to play games without lag.
I am using Airtel for last 3 years and I never faced any issues with the connection. One of the best customer service I have ever seen. It’s fast enough and costs have come down a bit while speed is improving
airtel also give u a 99 rs/- unlimited talk time landline plane which is amazing, u can talk where ever u want.
