Not available for me in Delhi/NCR,
I am on Rs.396/ 1GB per day / 84 Days plan till 21st October.
In fact, in my offers (*121#), no plan for me more than 28 days.
Porting to Jio after 21st October. I am happy with Jio on my other phone with Jio sim. No hassles of checking all the time if a particular plan is available for me or not.
Data speed is also poorest of Vodafone in my area (Airtel > Jio > Vodafone).
