Reliance JioFi is a device launched in the market by the Reliance Jio.I purchased the JioFi 3 from my nearby store.It’s price is Rs 1999.It’s a very good device.Look and Design is also good.It’s a very small device so that you can easily put it in your pocket.There is no need to insert it into the wall charger as it contains a Battery that gives a 5 hrs long lasting backup.It’s internet speed depends as per your location as in some location it’s internet speed is slow and in some areas it’s providing very good speed.It supports only a Jio Sim Card.The main disadvantage with the device is that you can’t use any other operator sim card in this device.The device is handy and really useful.You can consider buying it.It’s recommended product by me.
