4G LTE mobile WiFi routers, also known as CPE terminals, are built with a 4G or 5G communication module on the basis of the original router, and an IoT card (also called an IoT card, SIM card) is inserted into the router to receive 4G/5G signals from the base station to achieve a network connection. At the same time, the 4G/5G router can share the Internet with surrounding terminals through its own wireless WIFI and wired interface. At present, 4G LTE mobile WiFi routers are more common on the market, and the solutions are relatively mature.

5. How to choose the IoT card correctly for 4G LTE mobile WiFi routers?
What is an IoT Card? IoT card, also known as IoT card or SIM card, is a 2/3/4G card provided by mobile, telecom, and China Unicom operators. The appearance of consumer-grade cards is basically the same as that of ordinary SIM cards. The IoT industry's demand for device networking. Industrial-grade cards are divided into two forms: ordinary cards and SMD cards.
