Airtel Broadband is really good. I been using it since a month. Got the 60 GB for 16 Mbps speed, its working just as promised, The speed increases too at times yet consistent, And the download is just so fast, It happens in a wink of the eye, and I mean it . Airtel did disappoint me, a little two years back when I took a nano sim for my mini ipad, With a lot of extra charges.
But not this time around. They improved a lot and their charges have become a little more customer friendly since the last year. Must appreciate that.
