I dont really understand it... Could someone please explain to me how they both work...Im not the best and brightest person when it comes to understand it .
Basically your phone works as a modem to the internet & other devices with wifi can connect to your phone & then to the internet, so your phone works as a router too
Depends what you want it for, if for instance you had a laptop or desktop pc & needed to connect to the net you can do so via your phone.
