I am very satisfied with JioFi.I am using this device above 1 year when it is lunched. Today I share my personal opinion and experience about this JioFi in mouthshut.The internet speed and network capture power is so good.It is so helpful for me. The charging speed is so good .It is backup upto 1 day with continue use.The network show display helpfull for showing good or bad network covarage.JioFi is easily sync with My Jio app.The device is small and easy to carry in pocket .I suggest who are travelling a lot use JioFi.In JioFi one nano sim facility is available. We use any sim other than Jio sim. The jio customer service is so good and friendly. When I faced any problem for connecting JioFi I was calling to Jio customer care and they are really so help full.JioFi recherge pack is effectively low compare other company. After coming the Jio all things are change .We are experience a better internet. which are not buy a 4G phobe they are easily effort this JioFi and enjoy the calling and internet facility. Thank reading my review.
