A 4G dongle is a small, portable device that plugs into a computer or other device via a USB port to provide internet access using a mobile 4G network. It works by accepting a 4G SIM card to connect to a cellular network, allowing it to create a personal WiFi hotspot for multiple devices or provide direct internet access to a laptop. Key features include portable design, plug-and-play setup, and speeds up to 150 Mbps download.
How it works
Uses a SIM card: You insert a 4G SIM card into the dongle, which then connects to a mobile network.
Provides internet: It provides high-speed internet access similar to a smartphone, but can be used on devices like laptops, tablets, or notebooks.
Can create a hotspot: Many models function as a WiFi hotspot, allowing multiple devices (often up to 10) to connect to the internet simultaneously through the dongle.
Key features
Portability: Compact and lightweight, making it ideal for use while traveling or in places without reliable WiFi.
Speed: Supports high-speed 4G LTE, with typical download speeds up to 150 Mbps and upload speeds around 50 Mbps.
Easy setup: Most are plug-and-play, meaning they work without needing additional drivers.
Connectivity: Connects to devices via a USB port, and some models can also share the connection wirelessly with up to 10 devices.
Power: Many are powered via the USB port they are plugged into, although some battery-powered mobile hotspot versions also exist.
Other features: Some models may include an LED indicator to show network status and a MicroSD card slot.
