The Internet of Things card is a communication number card specially launched by operators for Internet of Things equipment and smart industrial equipment. Its appearance is similar to that of a mobile phone card, but it is usually not allowed to use personal mobile phones or personal entertainment to surf the Internet.
Because they are all enterprise-level products, the Ministry of Industry and Information Technology and operators have strict control over IoT cards, so they cannot be purchased in business halls and many places, nor do they support individuals to purchase and use them.
Because of its wide industrial applications, the Internet of Things card is also universal nationwide or globally. In other words, the Internet of Things card in Chongqing can also be used in Beijing; Beijing's Internet of Things card can also be used in Chongqing. Then you don't have to stick to it. You must have bought it in Chongqing.
Because of the use of industrial equipment, the card and tariff are not very expensive, but the project loss, equipment maintenance and personnel travel after-sales expenses caused by network power failure are high. Therefore, the most important thing to buy an IOT card is not the distance, but the stability and security.
In terms of stability and security, the first choice is definitely to find operators to purchase directly, but operators usually do not do terminal sales or do not do non-batch-level, non-heavyweight corporate customers. Of course, if you are a government, enterprise or listed company, it is recommended to choose an operator first.
If not, you can only choose a third-party enterprise that has a cooperative relationship with the operator, or an agent of the operator, such as Sichuan Yuhuan Star Chain Communication Technology, a company that has formal cooperation with the three major operators. When choosing a third-party company, honorary qualification, authorization, management background, renewal fee, after-sales service and price are all factors to be considered.
Finally, in the choice of suppliers, don't be greedy and choose IOT cards sold by merchants such as Taobao and JD.COM. Because the Ministry of Industry and Information Technology expressly stipulates that IOT cards should not be sold on e-commerce platforms, it is illegal to sell them on e-commerce platforms; Since it is illegal, there is no guarantee, and it may not be used for minutes.
