Want to share my experience of airtel4g it was not good experience for me so I want to share with you maybe it will help you for choose best Internet plan. I have used Airtel for JEE but I found it not useful the charges are very high Internet speed is very low. If you want to use good Internet speed I suggest you to go for NGO now they are giving free Internet for 3 months this is very good for you should go for it . I will give you to start to airtel4g because that demands much more money in compare to other four G Internet service provider . . . . .
