I have used airtel mobile operator for a long period of time.i feel like dumb when I hear about other mobile operaters companies plans they were too cheap as compared to mine one.i recommend all of you to use others cheap operator which will atleast provide you good data plans and calling plans.Using airtel mobile operator was my foolishness and I strongly reccomend you to buy some other mobile operator.Airtel mobile operator will only provide you the network but the cost and expenses are very high that the users takes the decision to port their mobile operator
