With JIO Prime and unlimited daily internet, most other providers have come up with similar plans for prepaid. While JIO unconditionally gives the plan for new and existing customers, some other providers have some catches. Looks like Airtel and IDEA too have similar plans for new and existing users. So currently (as of 3/27/2017) is Vodafone the only provider who does not provide this offer for existing customers? I do remember that vodafone had announced a similar offer with an end date of March 15, but myself or none of the people I know of has got the offer.
