A friend of mine bought this JioFi and had been using it until Jio offers Expired. But after it expired, my friend tried to use it with a different 4G sim card but it didn’t work. JioFi is a device only for Jio sim users and not for other sim users.
It is not a good device and I would not recommend u to buy it. But if u would like to use jio sim only then this device is actually best but only for jio users. But then u can use it as a Hot spot but other sims won’t work.
Hope my review helped you guys.
