Do I need to cancel the card that is already empty?

First, if there is arrears. The arrears record will not be cleared, and you need to go to the business hall with your ID card to cancel it, otherwise more expenses will be incurred.

Second, the number will be cancelled after three months of arrears, and the money will not be deducted, but the identity information has been blacklisted. To cancel the blacklist, you need to make up the phone bill you owe. After the identity information is blacklisted, the identity number can no longer handle the business of the telephone number operator.

3. If criminals collude with the "mole" of telecom operators, they will use the "empty number card" that has not been put into the market and has not been activated to build a platform, connect the mobile and telecom operators' servers to register accounts and send and receive verification codes.

The empty number does not need physical card and real-name authentication. Compared with the previous black card, it is basically a zero-cost crime, with huge profits and great harm.

Criminals and operators "ghosts" falsely register Internet platform accounts for sale, and a single micro-signal can be sold to 30 yuan at the highest. Bank cards are more expensive, and online fraud is profitable, but it cannot be traced back. The huge market demand has spawned a new criminal model of SMS hijacking using empty cards.

Generally speaking, the empty number is the number that the operator has not put out, which is out of reach for ordinary users.

Extended data:

Real-name mobile phone cards do not need to be cancelled quickly, which will affect personal credit information for a long time!

The first China Mobile Economic Development Report 20 19 released by Global System for Mobile Communications shows that China is the largest mobile market in the world. By the end of 20 18, the number of independent mobile users was close to1200 million, accounting for 82% of the total population in China. Every user in China had 1.3 SIM cards.

This has produced a large number of second-hand SIM cards, some citizens throw them away, some citizens keep them at home, and only a few citizens will go to the business hall to cancel their accounts.

For abandoned SIM cards, China Telecom, China Mobile and China Unicom are the safest measures.

1. For the mobile phone SIM card that has not been used for a long time, the customer service representative of China Mobile said that if the SIM card is not used, it is necessary to bring the ID card to the local directly affiliated business hall to cancel the account. If the SIM card is lost, it will not be reissued, and the system will automatically cancel the account if the arrears are stopped for more than three months. Call this number to remind you that it doesn't exist, so don't worry.

Secondly, the customer service representative of China Unicom said that the SIM card is no longer used, and it is necessary to bring the original ID card to the self-operated business hall of Chongqing Unicom to cancel the account. If not, it may lead to high arrears, or be blacklisted, and even have a certain impact on personal credit information. If customers want to apply for Unicom business again in the future, it will also have an impact.

The customer service representative of China Telecom said it must be cancelled. If it is not cancelled, the basic package fee will be generated every month. Citizens need to bring the original ID card to the business hall for cancellation. If the SIM card is lost, please don't worry. The business hall can check the SIM card information through the ID card and then cancel it.
