I am using airtel sim from last year I found it will be good with its 4G speed and calling but that was not.
Most of the time I want get network at my home and I feel very disappointed of buying the airtel sim and some time in network coverage area I not able to surf my browsing because of very slow speed.
I am feed up of this sim, I called so many time costumer care to solve but they didnt even cared and I kept calling but there was no use And I called airtel to check my network problem at home, What happend next they told me we have no service in this area.
it was so funny for me when they told this it was really very funny and shame on Airtel.
Why the hell they not not improve there network issues instead of competing with jio and other network if this goes continue, no one will buy Airtel Sim and no one will trust this types of frauds.
I will suggest you not to buy Airtel sim is waste of your time and energy, You can buy Vodafone which has very good network and internet speed and many more offers than any other SIMs.
