We are living in a 4g era but still some people dont have 4g enabled phones and want to use 4g on thier phone.is it a problem then? No the good news is yes you can use 4g on your 3g phone just with enbling wi fi of you phone.thanks to reliance jiofi3 the mrp of the same is 1999 rs for the device nd no charges for the 4g data till march 17. jiofi3 gets activated instantly by verifying your ekyc documents like adhar card no and finger prints.10 devices can be connected simultaniuosly and per day data limit is 1gb. after that speed gets reduced to 128kbps.you have to charge it for 2 hrs and it gives a good back up of 6 to 7 hrs after that.service is after sales is good.its a lightweight device which can be carried in your pocket.you can do free calls and messages by simply downloading jio4gvoice app on your mobile and connecting it to the jiofi3 device
your user id and password comes with it so your data cant be shared without your permission.overall it is a very good product and I am very happy with the same and recommend it to the people who uses 30gb high speed data per month.
