The best way to do this is to download The Sims 4 on a computer, make sure you have Origin installed, then take all the files and put them on the USB. When you plug USB into the laptop or PC or whatever you are going to plug it into. Make sure you have Origin and are logged into your account.
Then transfer the files from the USB to your Documents folder and you should be able to play it by clicking on The Sims 4 Icon in the folder. I hope this helps!
