Hii all I bought a JioFi 6 months ago @ 1999 but now you can get it only 999 rupees.Along with it 6 month free plan has been given.You can use any device, any time, any where even when I dont get other network.Multiple devices can also be used.Its very small in size and easy to carry.Once charged can be continued 24 hour for me.A slot for memory card has also been provided which support upto 16 GB.As this device only support Jio sim so speed provided by it is also high.Who use 3g phone can purchase a jiofi.
