The data card just does not work and the customer support is terrible. I bought the data card a month ago and sadly it hasn't worked for me for even a day. I've been back and forth with the customer support but they are pretty dumb and do not know what to do. On top of that, some of them act really rude. Overall, pretty terrible and I can say I am not going for any Airtel product EVER!

I'll give you the gist of the review here - Save yourself a lot of trouble and don't buy an Airtel Data card. If you feel like wasting 6000 Rs., just put it in the center of your room and burn it. That would be much better than investing in the Airtel Data Card.
Hope this helps,
