For me too, I am checking every alternate week on Vodafone/Idea website for their data plans since JIO was launched. And neither of them have any changes. May be they have some hidden plans or corporate plan which they don't reveal to customer on website, as my friend who has Idea Corporate Plan got increased data from 512 MB to 1 GB last month.
Why Vodafone/Idea don't update their plans on website, if they have new plans in offering?
