My sincere advise not to go with airtel postpaid data card. I took it yesterday with 3.1 gb plan and I just saw a satyamav jyate episode on you tube about 35-40 min and checked my usage consumption the usage consumption was 750 MB.
I was shocked to see my consumption and I called to CS department they said they are charging like that only. They are charging the browsing cost also. I was very much disappointed by airtel and I am discontinuing my plan.
Thanks
