Jiofi hotspot is ver good for every person who uses 2g or 3g phone but as nothing is perfect in this world so there are some problems in the hotspot which irritates the user lot.
for mine side there is a big problem in this device is that whenever I call someone with jio using jifi router and when the call get connected the voice is first of all not clear and I get sound or the person who is talking with me get sound while after 4-5 seconds which is very peculier.
so relaince industry shoult fix this problem.
we know none of the mobile operators are supporting u that is other problem bt the problem in u is to make a good device first over all its a good device
