Mobile USB modem

A mobile USB modem is a small device that connects to your computer and lets you access the internet using a mobile phone network. It looks like a USB stick and plugs into your computer's USB port, which is a kind of plug that you can often find on a laptop or desktop computer. When you plug it in, your computer will be connected to the mobile phone network and you'll be able to use it to get online. It's like having a tiny mobile phone with you that your computer can access!
