It uses 3G or 4G LTE cellular network to provide reliable high-speed internet connection and is a favored option among users due to its convenience, and portability.A USB modem can be very handy especially for devices that don’t have built-in connectivity options.

For example, desktop computers, some older laptops, or even game consoles, can benefit from the use of a USB modem to establish an internet connection. It can also serve as a backup internet connection for users with unreliable primary internet sources.

Since they are typically not connected to a power source, USB modems use very little power which enhances their efficiency. Furthermore, their plug-and-play nature eases the setup process, making them a popular choice for those who may not be tech-savvy.


1. External Dial-up Modems: Earlier, connecting to the internet required dial-up modems that used phone lines. Many of these were designed to connect with computers via a USB port. These USB modems were especially handy for people who traveled a lot, as they were compact and easy to set up with different computers.

2. 4G LTE USB Modems (Dongles): 4G LTE USB modems like the Huawei E8372 or the Alcatel Link W800 are devices that can be used with laptops or desktops to connect to mobile network data. These dongles are plugged into the computer’s USB port and deliver high-speed 4G internet. They are widely used by remote workers or people in areas with poor standard internet coverage.

3. USB Cable Modems: These are popular types of universal service bus modems found in many homes. Cable modems, such as the Arris SURFboard or the Netgear CM500, are devices that connect your house to your cable provider and deliver internet service through a coaxial cable. These modems often have a USB port for either directly connecting a computer to the modem or for other utilities such as shared network storage or printers.
