I have Idea iSmartpack plan of Rs 199 which gives me 4 packs. I have opted for 3 x 135 MB 3G/4G pack and 1 00 min voice pack. When I changed to this plan only 199 (4 packs), 299 (8 packs), 399 (10 or 12 packs) plans were available. Perhaps 499 was also available. I wanted just backup for JIO so opted for lowest 199 plan.
But today I checked, and found there are some changes. They gave added new plan of 249 with 7 packs, 299 now gives 10 packs. Besides 3G pack now increased from 135 MB to 150 MB.
I just hope Idea continues with these packs after merger with Vodafone, as Vodafone does not have such plans.
