What kind of card is a flow card or a property card?

Flow card generally refers to a number card with no voice communication function but only SMS and Internet access functions. IOT card is provided by operators for logistics network service enterprises, and is used for networking intelligent terminal equipment. It is only used for mass sales of enterprise users, and is widely used for enjoying bicycles, mobile payment and other neighborhoods, not for individual users.

I think the main difference between IOT card and personal mobile phone SIM/UIM card can be attributed to the different business application scope. IOT card is used to support the networking of hardware systems in smart farm, industrial management, logistics, traffic management, security, telemedicine, smart home, power grid and other professional fields. Ordinary mobile phone cards are just personal business.

It is a strategic product of the three major operators, and the price of the Internet of Things card is unified, stable and lifelong. It can be used in all cities in China and is specially designed for industrial equipment products, such as intelligent equipment, pos machines, vehicles and other applications.

From the appearance, there is no difference between IOT card and ordinary mobile phone SIM card. Functionally, both of them can realize wireless networking, sending and receiving short messages and other functions. However, the IOT card cannot make voice calls.
