@Maholmire Then that's what you want; check electronics retailers for "4g USB dongle" and stuff like that, you should have some luck, then make sure there are drivers before you buy it. Some phone companies will sell portable battery-powered hotspots, and those are easier to work with (no drivers required, works with whatever device has WiFi) but a little less flexible (like you can't do SMS and you are usually locked into one company instead of being able to swap SIMs).
