Well I generally use 3g for daily usages but when airtel launched its 4g in chennai as a launch offer I got 1gb free balance .what I noticed here is that 4g speed is obviously better than 3g.
But its speed is not that good as they advertise on television.my speed was some thing about 1mb/s well you will also get this speed in 3g pack.i will not recommend to buy 4g packs until 4g becomes what it really it is.
