Hello! Sadly, for all intents and purposes, it just doesn't work like that. I'm not saying it's impossible, because I have read how techies have made this happen - but it requires an insane amount of configuration, 3rd party software, a little programming, and a good grasp of linux. The router has to have the internet connection to share out to other computers. Go and get a wifi hotspot instead of a 3G USB device. The wifi hotspot, depending on the provider, should support up to 5+ connections. Another option is the see what ISPs are in your area, get service at your residence, then you could use the router. Hope this helps!
