USB modems (also known as USB dongles) are dedicated devices that supply portable Internet to one other device. USB dongles provide a faster connection than the alternative, mobile hotspots, and are also smaller and, therefore, more portable.
A USB modem is compatible with devices that have a standard USB port – so any computer, laptop, or e-reader, but only some tablets (and never iPads). Some USB modems require a software installation to run.
