When jio launched only for 4G mobile I was disappointed as I have been using a 3G one so I have purchase jio fii
it is an amazing device you can connect with almost 30 devices at the same time and you can use internet at a very good speed although I have not connected with lots of devices but I have connect my two phones and a laptop and sometimes one other phone yet its speed never seem to slow down I'm pretty sure that this is the best internet provider available
It connects easily with your phone its just need a password which is fixed you can look for it in the package or you can remove the battery and see if u need
It costs around rupees 1000 and it gives amazing offers it is very reliable and I have to say I loved it
