Puk code query

These are two different passwords. See below:

The full name of PUK code is PIN unlock code, which is usually an 8-digit decimal number, and its purpose is to unlock PIN. PIN code and PUK code are paired, and users can set the PIN code that needs to be input when starting the machine in the security setting options. It is a good protection habit to enter your own preset PIN code when opening your mobile phone, which can prevent illegal users from using this number when their mobile phone or card is lost.

[Edit this paragraph] Data function

After setting the PIN code, the terminal is allowed to try to enter the PIN code three times when it is turned on. However, if the PIN code is entered incorrectly for three consecutive times, the card will be locked. At this time, you need to enter the PUK code to unlock it, but the user does not know the PUK code and needs to go to the business hall to decode it. Users must not try to enter the PUK code, otherwise if they enter the wrong 10 times, they will enter a permanent lock state and cannot be unlocked. At this time, they must go to the business hall to apply for a replacement card. PUK code is not a mobile phone lock, but a card lock, which has nothing to do with the mobile phone! The relationship between the four passwords of SIM card: PIN code, PIN2 code, PUK code and PUK2 code. There are four kinds of SIM card passwords for all mobile users: PIN code, PIN2 code, PUK code and PUK2 code. The initial codes of these four passwords are provided by the operator who provides the SIM card. The relationship between the four passwords is as follows: PIN code (PIN 1) is the personal identification password of SIM card. If not modified by the user, the original password set by the operator is 1234 or 0000. If the startup PIN code is enabled, you must enter a 4-digit PIN code after each startup. The PIN code can be modified to protect your SIM card from being used by others. It should be noted that if you enter the wrong password three times in a row, the mobile phone will automatically lock the bank card and prompt you to enter the PUK password to unlock it. At this time, it is close to the edge of danger. Therefore, if you modify the PIN code without authorization, you must keep it in mind. PUK code (PUK 1) consists of 8 digits and cannot be changed by users. When the PIN code of the mobile phone is locked, and you are prompted to enter the PUK code, don't act rashly, because the PUK code has only 65,438+00 input opportunities. If you enter it incorrectly for 65,438+00 times, the SIM card will be permanently locked, that is, scrapped. The PUK code of some SIM cards is attached when users buy SIM cards, such as Shenzhouxing of China Mobile, while the other part needs to be obtained from network operators. If your PIN is locked and you don't know the PUK password, please don't enter it casually. At this time, the correct way should be to call the service hotline of the operator to which the SIM card belongs. After a simple user data check, you can get the PUK code and unlock the phone. This service is free.

[Edit this paragraph] Data expansion

Use PIN2 code when setting up mobile phone billing. If you enter it incorrectly for three times, the phone will need to be unlocked with PUK2 code, and the process is the same as the PIN code and PUK code introduced before. However, these two passwords involve network billing and the modification of internal information of SIM card, so they will not be made public. Even if PIN2 password is locked, it will not affect the normal use of the mobile phone. Therefore, PIN2 code and PUK2 code need not be deliberately ignored.

[Edit this paragraph] Solve PUK code

Solve the PUK code through the following channels: 1. You can go to the communication service hall 100 with your original valid certificate or service password, or you can entrust others with your original valid certificate and your valid certificate. Unit customers can entrust others to decrypt the PUK code with the valid certificate of the manager and the unit certificate or service password; 2. You can call the customer service hotline 10086 to decrypt the PUK code with the service password.

[Edit this paragraph] Basic introduction

The mobile phone has one or more passwords to prevent others from using the mobile phone without permission. PIN code and PUK code actually protect SIM card, which is a small card used to establish network connection in mobile phone. In most cases, your network operator or service provider can provide the best help about PIN codes and PUK codes. The most commonly used password is PIN (Personal Identification Number). You can set your own PIN code and enable or disable it according to the instructions in the user manual. PIN2 code is a pin code that provides the second layer of protection for specific mobile phone functions. It works in the same way as a PIN code, and your user manual provides more information. If the wrong PIN code is entered many times, the mobile phone will ask for the PUK code (personal unlocking code). PUK code is an 8-bit password provided by your network operator or service provider. If the wrong PIN2 code is entered multiple times, the phone will ask for the PUK2 code. Please consult your network operator or service provider for PIN code and/or PUK code. If you have consulted the service provider, but the password provided is still invalid, you must apply for a new SIM card from the network operator or service provider. The relationship between the four passwords of SIM card PIN code, PIN2 code, PUK code and PUK2 code All mobile users' SIM card passwords are divided into four types: PIN code, PIN2 code, PUK code and PUK2 code. The initial codes of these four passwords are provided by the operator who provides the SIM card. The relationship between the four passwords is as follows:

[Edit this paragraph] Personal Identification Number (PIN 1)

It is the personal identification code of the SIM card. If not modified by the user, the original password set by the operator is 1234 or 0000. If the startup PIN code is enabled, you must enter a 4-digit PIN code after each startup. The PIN code can be modified to protect your SIM card from being used by others. It should be noted that if you enter the wrong password three times in a row, the mobile phone will automatically lock the bank card and prompt you to enter the PUK password to unlock it. At this time, it is close to the edge of danger. Therefore, if you modify the PIN code without authorization, you must keep it in mind.

[Edit this paragraph] PUK code (PUK 1)

It consists of 8 digits and cannot be changed by the user. When the PIN code of the mobile phone is locked, and you are prompted to enter the PUK code, don't act rashly, because the PUK code has only 65,438+00 input opportunities. If you enter it incorrectly for 65,438+00 times, the SIM card will be permanently locked, that is, scrapped. The PUK code of some SIM cards is attached when users buy SIM cards, such as Shenzhouxing of China Mobile, while the other part needs to be obtained from network operators. If your PIN is locked and you don't know the PUK password, please don't enter it casually. At this time, the correct way should be to call the service hotline of the operator to which the SIM card belongs. After a simple user data check, you can get the PUK code and unlock the phone. This service is free.

[Edit this paragraph] PIN2 code

It is used when setting up mobile phone billing. If you enter it incorrectly for three times, the phone will need to be unlocked with PUK2 code, and the process is the same as the PIN code and PUK code introduced before. However, these two passwords involve network billing and the modification of internal information of SIM card, so they will not be made public. Even if PIN2 password is locked, it will not affect the normal use of the mobile phone. Therefore, PIN2 code and PUK2 code need not be deliberately ignored.
