I first bought this when jio had new launched his jiofi that around 2016 AD
When I bought jiofi it cost looking bar 2100 rupees and I used it for laptop and phone.
My experience has unfaithful to using that.
Jiofi battery backup is too bad when I bought it ran around 2.5 hours but now its coming 30 minute. That was the vast bad experience with jiofi.
Founder of reliance jio when launched there jiofi I seemed he was too busy to release that product.
When I connect my phone to jiofi suddenly got lagging and my phone got over heating every time during connected.
But now that jio sim I puted to my 4g mobile and I shared internet through hotspots to my laptop and jiofi was broked by me.
My opinion : strictly advice , Don't looking to jiofi. Buy 4g mobile and if would be volte.
