In case you exhaust the FUP (fair usage policy) data, then the speed reduces for you to 64 Kbps. The total amount of data that you get with this plan is 46GB. This is a decent plan for someone who just wants more data every day for a short period. Otherwise, going for a 23 days plan wouldn't make a lot of sense for consumers, especially when they can get better value plans by going for the 28 days or 30 days plans. Reliance Jio introduced this Rs 249 plan during the last time it hiked tariffs in December 2021.
If you want a 2GB daily data plan from Jio for 28 days, then you can go for the Rs 299 plan, which comes with the same benefits as of the Rs 249 plan but just with 28 days of validity.
