Can I use my SIM card in a WiFi modem?
Generally speaking, you cannot use a regular cellular SIM card in a WiFi modem. Here's why:
1. Different technologies: WiFi modems and cellular networks use different technologies to transmit data. WiFi uses radio waves, while cellular networks use mobile data protocols like 3G, 4G, or 5G.
2. Purpose: A SIM card is designed to identify and authenticate a device on a cellular network, not a WiFi network.
3. Hardware incompatibility: WiFi modems are not built with SIM card slots or the necessary hardware to interpret cellular signals.
However, there are some exceptions and related devices to be aware of:
1. Mobile WiFi Hotspots: These devices do use SIM cards and create a WiFi network using cellular data. They're sometimes called MiFi devices or portable WiFi routers.
2. 4G/5G Routers: Some home internet solutions use cellular networks and require a SIM card. These devices create a WiFi network in your home using cellular data.
3. Dual-mode Routers: Some advanced routers can switch between traditional broadband and cellular connections, and these may have a SIM card slot.

If you're looking to use cellular data to create a WiFi network, you'll need one of these specialized devices rather than a traditional WiFi modem. Always check the specific capabilities of your device and consult with your service provider for compatibility.
