JioFi has a strong connection . It is avaliable at any villages and forest . But some things are wrong with this that to work with it we want to insert Jio sim which is not good it means that if we does not have jio sim so we cant work with it and our whole money will be vanished. But the most wonderful thing is we can use jio sim even if we doesnot have 4G mobile.And it is also portable. One thing is good that we can change password and it can be only changed by laptop, if we do not have laptop so what we wlill not chanhed it., but if we didnot change the password and somebody have seen the password so he /she can connect through our network . And the password is also so difficult.
