A special USB modem allows your computer to connect to the same mobile network when you’re on the go. This tiny external USB device means you’ll get high speed HSPA internet wherever there is cell phone reception towers nearby for your carrier.

Either way you’ll need a data plan contract with a service provider that offers 3G speeds on an HSDPA signal. It is worth noting that some third party services now exist where you can purchase this access without having to have a separate cell phone plan.
