I have noticed the same after paid plans went active. Last week I was out of town, the modem was off and yet 4Gb was deducted. I assumed it might be a delayed accounting for data used earlier. Now everyday I see much higher deduction than usage. Considering how miserly Jio has become with data with low FUP and limiting upload speeds, I suspect this is willful. I wonder why they are so miserly when small ISPs are offering unlimited plans for low prices?
