I am using this phone from july 2016. Now after using it for long time I see the only positive point about it is that you can lock it to particular band, lke you can set it on band 3 or 5 or 23. Otherwise this is worst phone for such a price. I use it for just wifi hotspot. And it is fulfilling my purpose. Otherwise battery last for 12-15 hours.
Camera is of worst quality looks like 2 MP. The worst thing about it is display quality. Feature phone has better display.
It does not support video calling and you cannot use jio voice app for calling purpose on this phone. However you can use any third party app such as skype or IMO for video calling.
If I talk about value for money the only positive feature I found is selection of band as I mentioned earlier. Otherwise never even think of it.
