I purchase a aircel sim for 100 rs. Because it gives 1gb data and 15 rs talk time. But believe or not I hardly use this sim. The network are worst. Hardly I get any signal on my mobile. And it also deduct 30 rs from my main balance with out my concern. I try to contact aircel coustomer care but no one recive my phone. Till the day the dont refund my money. For first they give you many offer but day by day the service became worst. So I would never recommend aircel sim to anybody. It will suffers you a lot.
