Validity
While you only get the "unlimited" plans as prepaid with Airtel and Vodafone, Reliance Jio offers the same plan as both prepaid and postpaid offers. Anyone can subscribe to these offers from Reliance and Airtel by March 31, 2017, while Vodafone plans to rope in all its users by March 15, 2017. Each of these three plans will remain active until March 31, 2018, and come into effect on April 1, 2017. Vodafone, however, has confirmed that this plan is being offered to a "select" group of users, and we are not yet sure how the eligibility is being judged.
