Airtel is the best in all sim card oprator.When I use Reliance network then I couldnt got the good speed its good only for facebook not for anything. Then my friend tell me about Airtel network then I buy a sim of airtel, airtel network is the best in 3G/4G. And I use it in my twitter, facebook, whats app and all my social sites. I thanks to my friend to suggest me about this, it give us one click movement net, which is really superb.
My all works done in few minutes its like a time saver not time waster. Because when network is working with a big buffering then the user mod is off from net suffering in their system so the speed of airtel is too good.
