With the continuous development of society, China's science and technology are also progressing, and the Internet of Things technology is becoming more and more extensive. At present, China's 4G era is coming to an end, and it will usher in a brand-new 5G era. Before entering the 5G era, a large number of traffic cards began to appear. Tencent Wangka and Alibaba Baoka have launched unlimited flow cards, and people don't know which one to choose. In an environment where major operators are trying to seize the market, we also got a cheaper flow card. Now I won't rub WiFi everywhere. Next, I will talk about what an Internet of Things card is and why it can be so cheap.

What is an Internet of Things card? Internet of Things card is a function specially designed for intelligent hardware and Internet of Things devices launched by the three major operators. It is a card type that uses a dedicated number segment and an independent network element to manage intelligent software and network equipment. At the same time, the Internet of Things card is also the cheapest card on the market. Vending machines, bicycles and POS machines that we see on the street now are all realized through the networking of Internet of Things cards. It is said that they are still widely used.

What are the advantages of the three major operators? Mobile Internet of Things card has the characteristics of good signal and fast 4G network speed. Unicom Internet of Things card has the characteristics of 0 monthly rent, high freedom of package and good 4G network. Compared with the above two, the telecom Internet of Things card is the cheapest!

What are the characteristics of the Internet of Things card? 1. It is used all over the country and can connect networks all over the country. 2. Safe and reliable, private network dedicated, high security. 3. Stable price, uniform specifications and stable price. 4. Online monitoring, real-time monitoring of equipment operation and traffic consumption in the background. 6. Remote operation, which can recharge, pause, activate and diagnose the card remotely.

The most important thing to note is that the Internet of Things card can't be used to make phone calls, send text messages, and can't be inserted into a mobile phone, which is different from ordinary traffic cards. In fact, the Internet of Things card has existed for a long time, and it was the Internet of Things card that was used on the POS machine before. Only in the 2G era, the network speed is slow, the traffic is small, and it is not popular. Internet of things cards are only for group or enterprise customers, and individuals can't buy them. They can only buy them from third-party card vendors.
