Just observed! Vodafone has silently dropped Rs 49 plan with validity 28 days.
Now you only have:
Rs 39 with 14 days validity (Rs 30 talktime valid for 14 days)
Rs 79 with 28 days validity (Rs 64 talktime valid for 28 days)
So, now, the cheapest way to get 28 days validity with some talktime worth using is Rs 79 !
Note: Vodafone still offers Rs 24 recharge with 14 days validity (No additional talktime, only 100 night minutes to Vodafone numbers)
