I hope idea is giving 1. 2Gb free 4G data(5days) for non gprs handset users. I have already got 1GB 4g by sending GO4G which was expired a month back. And now, Yesterday i got 1GB 4G data in my number which was used in 4G handset two weeks back and now using in non GPRS handset. Try changing your sim to non gprs handset under 4G network for couple of days or one week and see what happens. PS: This is unconfirmed , try in your state and reply here.
