With the update and development of technology in the times, mobile phone cards and phone cards have been widely used in people's lives. With the continuous development of smart devices, the connection between things has become more frequent, so a new term "IOT card" has emerged in recent years. As the name implies, it is a way of networking between things.
Compared with mobile phone cards and phone cards, IoT cards still have their own differences. It only has the function of surfing the Internet, and has no other functions, including basic functions such as dialing and text messages.
However, due to the imperfection of the policy and the unique nature of the IoT card, traffic cards modified by it appear on the market.
Many people use the IoT card as a traffic card, but many of them have reported that the IoT card is locked for no reason, so why?
Nowadays, in our life, many devices need to be connected to the Internet, such as shared bicycles, etc., they use IoT cards, which is why operators develop IoT cards. After these devices put the cards in, they basically will not be taken out.
Also because of this reason, after the IoT card is activated, it will be bound to the device where it is located. In this case, if the device is replaced, the card will be locked. It can be seen that the card lock is a protection mechanism for the card. For example, if your device’s IoT card is stolen and others continue to use your traffic to a large extent, this is not only a waste of resources but also a violation of your own rights and interests. This situation has not happened before. Therefore, the operator has introduced the card lock function.
However, if the IoT card is locked, it can be unlocked. This needs to be submitted to the corresponding operator for unlocking.
Summary: The IoT card is a card launched by operators for the era of the Internet of Everything. We need to be clear about its scope of use and use it in a reasonable manner. Remember to use mobile phones for personal networking, etc. This situation is not allowed, and it will be banned if found!
