Hmm, so the benefits of the 399 plan remains the same except the validity has been reduced to 70 days and the new 459 plan has the same benefits as the previous 399 plan with 84 days validity. So a hike of Rs.20/month...Not a bad deal. Post FUP data speed has been reduced from 128 kbps to 64...doesn't bother me much coz hardly could do much with 128 kbps previously.
For the Rs 149 plan the data limit per day is just 150 mb, so yeah that is a bummer. But look at it this way, for a paltry 4 bucks/ month extra (153/month) you could have 1Gb/ day data limit if you opt for the 459 plan. Granted, a bit expensive for a lump sum payment but you'll have to recharge after 28 days for the Rs 149 plan anyways.
