Jiofi is a good device to use as we can carry it easily where we go.But I must say that its internet speed is very slow and sometime it just dissapointing .i have purchased it .but have a very bad experience. .as we know jio gives services in very less money .his service quality is also not good .we can connect 20 to 30 devices at a time but the main thing is we cant enjoy the high speed .overall its just waste of money .in my view dnt purchase it
