Reliance jiofi is one of the waste products that jio has launched along with lyf phones. Jio promised to give 1gb of daily internet and unlimited calling with this jiofi. The uploading and downloading speed is very slow and not upto the mark.
Battery backup is awesome.
Does not support any other sim card.
Bad network.
Little thicker but can be easily carried in the pocket.
As of todays price and service I do not recommend to buy this at all.
