I have what is probably the world’s worst internet connection and as such, I’m unable to download the UE4 files at all (with the exception of the Launcher).
Are the UE4 files available as a set of DVD’s?
Don’t you have WiFi areas where you live or webcafes?
I’m two hours from the nearest wi-fi hotspot or webcafe.
In the 80s there were computer magazines full of listings and we typed them in manually 
Get someone to send you a HDD with it on there, thats probably a good solution if you want any significant amount of UE4 versions and marketplace content. You might get away with a usb stick otherwise.
