For last few days there are banners about Idea 3G Prepaid data balance carry forward to next month. If we recharge before validity is over, remaining data is supposedly carry forward till next validity date.
I have not tried it yet.
Below link is of epaper of our local newspaper of 01-04-2015 which has Idea advert on 1st page about data carry forward (in Marathi).
