Till 31st Dec, topup of 100 gave Rs.81 talk time AND 10 GB data voucher. Now, it gives only Rs.81 talktime. Same for all other topups. Now, one needs to pay extra 101 for 12 GB data (with no talktime).
So by one move, Jio has increased the cost of data.
For those thinking what to do with the balance, the balance can be used for recharge from myjio app. Many people were using cashback offers of various apps to do small topups and then use the accumulated balance for recharge.
