Overview: How can a miniPC model with its own SIM card slot realize 4G Internet access in places without wired network and WIFI by expanding the 4G module + SIM card? The prerequisite is that there is 4G network coverage in the usage scenario.
PS: If miniPC is not installed with 4G module, inserting SIM card directly into the motherboard can not recognize the SIM card, it needs to be equipped with 4G module to recognize it. 4G module is an optional accessory, there is no such module in the factory by default. Before purchasing the product, you can contact customer service to purchase it, or you can purchase the 4G module extension by yourself. (Note: When purchasing the 4G module, please make sure that the 4G module meets the network standard of your local network operator, for details, please consult the 4G module distributor or network operator).
