I bought jio fi this at cost 999 rupees but jio didn’t given the jio sim along with this. It’s provide the real 4G speed which we really want I really enjoying the speed of internet. But I much disappointed with the battery life which have 2400mAh works upto 4-6 hours only. It have also memory card slot which can be used for transferring data and the price of this device is high. Thank you
