When jio sim newly released I don't have any 4g phone so had to buy a jiofi worth rs 2000 to avail the amazing free offers of jio. But to be fair I am not satisfied with it. Firstly 2000 rs was a bit too high for only a router but had to buy it as there was no.option otherwise. Secondly it has too much conne tion issue and it is comparetively slow than if u use jio in your phone. Thirdly it's battery back up is not upto expectation u have to charge it twice a day .u can't use it while charging as it gets heated .sometimes connection problem occurs. so after I buyed a 4g phone I selled it at only 500 rs. Jio has dropped its price but still I think 999 is also high for this
