If you work on net you can buy the JioFi because its comes with jio 4g network and true 4g speed you can also call it a pocket wifi for speed test its speed is as per the speed of jio sim network is better and the services are also as per sim for the official work or network jiofi is better wifi than other
If you work on computer or laptop dont buy a dongal because the jiofi can conect with 10 laptop or 10 phone as compare to the dongal it is best
Some time you want to gace the problem of speed or network.
?????Thanks for watching?????
