They advertise like airtel is the only network having highest speed across india but you will never get 10 % of their claimed speed.
Recently when I got airtel 4g hotspot then the engineer came to my home to give me demo of their services, speed were good at that time but that was on his airtel id which he was given , but when I got my connection ready then I got 10 % of that speed like 1mbps.
When I tried to contact him he was not picking up my calls and refused to return anything.Airtel is the cheater and cant say anything about it right now .only one thing is for sure that they cant be trusted, pricenis the most highest but services are the worst.
