In india there is no need to tell any one about jio. jio successfully advertise itself in indian market. it provides so much facilities like video cal, l data talktime etc. people also enjoy this a lot.
but it is only for the 4g mobile phone user. theirfore the 2g and 3g user are sad on this. I think to rectify this sadness of people who uses like 2g or 3g the company discovered a solution for it as jioFi.
specially I have a 3g hand set and I am unable to use the jio sim and use other data plan .as the jio fi launched I am so happy and use it successfully . its spped and connectivity is as good as jio sim.
so I recomend other to use and enjoy this facility.
