As far as MBB packages are concerned i think the one year plan is the best....
Basically its Rs18000 50GB/month for 12 months
Its not exactly 12 months but rather (12*30) = 360 days
But nevertheless assuming it to be 12 months...per month it comes to 18000/12 = Rs1500/month
Now Rs1500/month for 50GB's is i think pretty good.......and in my area speeds are relatively good as well so its an excellent option for me.
