I am using a airtel sim which is better but is is not working properly on by some palace and it is working time is quite long, it is a advertise that on mobile, tv that it is a best network area of our India but it is not that because it is network is not connect properly but it is better then other sim which is talk time rate is to high so by on the price this sim is cheap then other .
So it is a better sim to the other so I refer to other that it is a better sim you can use this sim .
Thank you
