Which Cellular Modems Use a Smaller SIM?

Up until more recently, cellular modems – whether that be a USB modem, mobile hotspot, or embedded router – were using the mini, or 2FF size SIM card. Now, we’re starting to see more devices requiring a micro or nano SIM card – like most cell phones use today. 

Here are some of the most popular embedded routers and the SIM card size they require:
