JioFi is a device from Jio that lets you use your 3G or 2G phone with 4G wifi using this device.
I recently got it for a cousin and tried to check it before gifting, The internet speed is good. However, the Connection isnt a reliable one. The connection keeps on breaking at regular intervals which is disappointing.
Service from Jio for JioFi isn’t upto the mark.
Since now-a-days almost all phones come with 4G enabled, I dont see any use of putting money into this device unless you dont want to change your 3G phone and upgrade to a new one. I will suggest to rather buy a 4G smartphone than an unreliable JioFi device.
I dont recommend buying it.
