I am using jiofi 3 is really a good device and I am using it. it is a having a good battery - pack with at reasonable price. jio sim speed is not that high when we use sim by putting it in mobile. also we can access many mobiles only by one sim. we can check all the informatiion of jiofi by our connected mobile. way of seeing the information is -
1) connect your mobile by jiofi 3 .
2) access the website - "jiofi.local.html" .
3) login on the site, tb=he default login name is - administration, and default password is also- " administration" . After login we can change our login password, user-name, official name and also we ca see the charging status. number of connected device. Also we can make the call by our jio sim. the way for making the call by jio is -
1) install "jio4gvoice"
2) register on this by typing OTP, remember OTP will be send on alternative mobile number.
3) now you can directly call by jio.
I will recommend to use this device it is good and portable wifi device.
the data is restored at 2AM in jio sim daily. remember this device is more useful nd much better in cities.
