5G SIM routers can have anywhere from one to as many as eight or even more SIM card slots, depending on the model. Dual-SIM routers support two SIM cards simultaneously and are often used for basic redundancy and load balancing. A multi-SIM router typically supports four or more SIM cards and is generally used in business environments, remote locations, or situations where high availability and network stability are critical.

What’s the difference between a SIM router and a SIM modem?

A SIM router and a SIM modem are both networking devices that use a SIM card to connect to cellular networks for Internet access, but they serve different purposes and have distinct features: A SIM router is designed for creating a local network and sharing an Internet connection among multiple devices, making them suitable for homes, small businesses, and remote locations where traditional broadband connections are unavailable or unreliable.

A SIM modem, also known as a USB dongle, adapter, or cellular modem, is a portable device that connects to cellular networks via a USB port on a computer or other compatible device. These modems don’t usually have built-in Wi-Fi or multiple Ethernet ports. They provide cellular Internet connectivity to one device at a time.
