Airtel — failure internet connection

Worst internet connection. One of the worst networks in India. It is similar to the basic 2g internet connection claiming that they re providing 4g services. Don't opt for Airtel because they praise themselves to be the world's fastest 4g network.
They cheat us by introducing to the plans and making them pay for it. The network will be running smoothly for a day. But after a day, the network lags so much and it starts to run like 2G intercom network.
