Internet of Things cards are mainly SIM cards provided by mobile operators such as China Mobile, China Telecom and China Unicom for the Internet of Things, especially in M2M field. According to the physical form, it can be divided into plug-in MP card and patch MS card. The appearance of the Internet of Things card is basically the same as that of the ordinary SIM card, but the difference is that the Internet of Things card is mainly aimed at enterprise development and production, mainly used for research and development of equipment, and has no voice function, and is mainly oriented to enterprise users, generally not open to ordinary consumers.

In recent years, China's Internet of Things cards have developed well, and the number of cellular Internet of Things end users has been increasing. The three basic telecom enterprises in China have developed 654.38+300 million cellular Internet of Things end users. The good development of IOT card market benefits from the development of downstream market. At present, China's Internet of Things cards are mainly used in smart commerce, smart manufacturing and smart transportation.

Specifically:

(1) Smart public enterprises are smart applications based on Internet of Things technology, mainly focusing on water supply, power supply, gas supply, heating, public safety, environmental protection, transportation and other areas that serve people's livelihood. Thanks to the rapid development of smart cities in recent years, the market has been growing.

(2) Intelligent manufacturing is an advanced production mode based on the deep integration of new generation information technology and advanced manufacturing technology, which runs through all aspects of manufacturing activities such as design, production, management and service, and has the characteristics of self-perception, self-decision-making, self-execution, self-adaptation and self-learning, aiming at improving the quality, efficiency and core competitiveness of manufacturing industry.

(3) Intelligent Transportation mainly refers to the integration of Internet of Things, cloud computing, big data, mobile Internet and other IT technologies on the basis of intelligent transportation dispatching system, collecting and processing traffic information through information technology, and providing real-time traffic data services.

Faced with a variety of IOT card companies in the market, it is necessary to identify and screen out the stable IOT card companies.

(1) It is the easiest to purchase directly from the official channels of the three major operators, such as China Telecom IoT Card, China Unicom IoT Card and China Mobile IoT Card;

(2) Intuitively understand the company's operating conditions through official website, WeChat official accounts or other websites. For those companies with close registration time and abnormal business performance, we should treat them as appropriate when choosing such IOT card companies to cooperate. This general strength is not strong and it is prone to problems.

(3) Powerful, large-scale and stable IOT card companies generally attach importance to brand promotion, product introduction and other information. Therefore, to check the stability of an IOT card company, you can learn about the company's recent developments in official publicity accounts such as official website, Tik Tok and WeChat official accounts.

(4) IOT card is a long-term product. In the process of use, problems such as traffic inquiry, machine card binding, recharge renewal, card number reset, activation, etc. need long-term after-sales, timely response and answers from technicians, and the stability of an Internet of Things card agent depends on whether after-sales personnel provide consulting services.
