I had used once in my life and had got a lesson to not get any airtel no. Or sim. The tarrif rates are so unexpected and not understanding that I had made many faculty recharges in it. So I preferred to port it into other Telecommunication operator. Don’t know how to make a consumer mind tarrif so that they could make a nice and good call or sms or internet. The worst is the internet. You can only find the speed in selected areas and rather you have to use 3G or 2G in the price of 4G.
