How do I turn a mobile card that is in normal use into an empty number?

To turn a normally used mobile card into an empty number, you can cancel the number (that is, the number is invalid) and call forwarding (the number is invalidated virtually).

If you want to completely abandon the use of the mobile card, you can select the "Number Cancellation" function and follow the steps below

1. First confirm that the number meets the cancellation conditions through customer service (which can be ** customer service, customer service manager, online business hall customer service, etc.). If the number has signed a contract agreement, guarantee agreement, group agreement, etc., it is not only convenient to apply for cancellation of the number, but also needs to negotiate the cancellation of the contract before applying for cancellation of the number.

2. After confirming that the number can be cancelled, go to the designated business hall to go through the cancellation procedures with the real-name certificate, if the number is not real-name, you need to go through the real-name before you can cancel it. Real-name handling is a requirement of relevant national laws and regulations and must be implemented.

3. After the cancellation procedures are completed, there will be a number retention period, at this time the number is unavailable but the number will not be invalid, if the user regrets it during this period, the number can be replaced. Note: Only when the number retention period is exceeded, the number will prompt an empty number, and the number will prompt shutdown before the retention period is exceeded.

4. If you are unwilling to go through the formal cancellation procedures, the system will automatically ** this number when you are in arrears for more than 3 months, but at this time, it will affect the personal credibility of the real person and have an impact on the user's later handling of communication products. It is recommended to handle the cancellation normally, so as not to affect the later business handling.

If you want to keep the number in normal use, and let others call your own number and the prompt "empty number" appears, you can use the call forwarding function. If you can set the unconditional call status to be transferred to the wrong number, the other party will hear an "empty number" prompt when dialing. At present, the relatively safe empty number settings can be cornets, virtual numbers, and wrong numbers.

However, it is not recommended to set up a value-added service number or an international number to avoid losses, because a transfer fee will be charged if the call is successful.

Tips: 1. The empty number can be set as a short number (such as removing a few digits from the middle of a normal number), a virtual number (a temporary number obtained through the multi-number function), and an error number (an obviously wrong number, such as 123, *11, etc.).

2. It can be implemented by software. At present, most smartphones can use APP software, such as caller, number manager, optimization master, etc., all have a "do not disturb" service, which can be set to meeting, break, free of all disturbances and other statuses, and you can choose your own prompt sound. Not only the empty number prompt, but also the busy line, shutdown, etc. can be set.

Enter 21 999999 in the dial field, then dial it and set it to empty, if you want to cancel, enter it in the dial field, and then dial this to cancel.

Call the manual customer service to ask, maybe someone complained.

The number used in China is 11 digits, of which each field has different coding directions: the 1st-3rd digit - network identification number; Digits 4-7 - area code; Digits 8-11 – User number. The number is also the so-called MDN number, that is, the number that the calling user needs to dial when the mobile user of this network is called, and it adopts the coding method; It is stored in the HLR and VLR and transferred on the MAP interface.
