How can I solve the problem that the traffic card of the public network intercom cannot be used after changing the device?

The flow card of the public network walkie-talkie cannot be used after the device is replaced because the flow card is an Internet of Things card, and the current Internet of Things card requires the binding of the machine card.

Machine card binding is a measure to regulate the Internet of Things card industry.

The Internet of Things card is a card launched by China's three major operators and adapted to use with smart and networkable devices. The Internet of Things is considered by the communications industry as the future. At the present stage, the three major operators have given a lot of preferential policies for IoT cards, and the price of the same traffic IoT card will be even cheaper.

It is precisely because of the low cost of IoT cards, and some targeted IoT cards are cheaper, which allows some channels to illegally invest such IoT cards in the personal market and earn the difference.

At the beginning, the IoT card does not require identity verification, and these IoT cards that are invested in the personal market will also be used in some gray areas and even be used for illegal activities.

In the final analysis, there are huge economic benefits, and there will be some channels trying to find ways to exploit the loopholes, which has also made the Internet of Things card market always chaotic.

The Ministry of Industry and Information Technology has requested the three major operators to regulate the IoT card market, and there are certain measures. This includes the registration of the identity verification name system for the IoT card, the requirement for the binding of the IoT card machine card, etc.

The implementation of machine card binding started on August 1, 2018, and the operator stipulated that: hardware devices using IoT cards need to be bound with IoT cards, one machine with one card, and card machine integration. If it is found that the IoT card replaces the hardware device, the IoT card will be shut down.

This is why the data card cannot be used after changing the terminal of your public network intercom.

In fact, it is not just a public network walkie-talkie. There are still many Internet of Things cards that are advertised and sold on the Internet. Some people have purchased them and placed them on mobile phones. These Internet of Things cards will also be locked when they are replaced.

The resumed use of the IoT card that has been suspended requires a new application.

If your IoT card was purchased directly from the operator, you can understand the binding through the operator. Generally, you need to bring an ID card or a voucher for an IoT card to go to the operator's business hall, or ask your account manager for the IoT, or ask the local operator's customer service.

Or if you bought the IoT card from some agents, you can only use these agents to handle the unbinding of the IoT card, but in fact, it will not delay for a long time. The operation is relatively fast.

By the way, some IoT cards are now used on mobile phones, and card replacement may also be discovered by the operator ’s management system, and such an IoT card that has been suspended by the operator ’s system cannot be used again. I can go to an agent to change a mobile phone card, which is also more likely to appear when individuals currently purchase IoT cards. Moreover, sometimes such a card is a batch, or it may be that other people are affected by the card, and the risk of using the Internet of Things card on the mobile phone is still relatively large.

All in all, the current traffic card on the public network intercom cannot be used for another terminal. This is mainly because the public network intercom uses the Internet of Things card, and the reason for changing the device needs to contact the card binding.
