An HSDPA USB modem is a small external device that allows a computer with a USB port to connect to high-speed 3G wireless networks. 3G networks are high-speed networks often maintained by cellular service providers to allow cell phone handsets to access the Internet. The modem connects to a computer’s available USB port and is sometimes supplied by the cell phone service provider that the user has signed up with for 3G network access. Warnings Writer Bio
