PUK code full name PIN UnBlock (PIN unlock code) is generally 8 decimal digits, the purpose is to unlock the PIN. The PIN code and the PUK code are paired, and the user can set the PIN code to be input at the time of power-on in the security setting option.
It is a good protection to set the default PIN code to prevent unauthorized users from using the number when the phone or card is lost. After setting the PIN code, the terminal allows to try to input the PIN code 3 times when the phone is turned on. However, if the PIN code is incorrectly entered 3 times, the card will be locked. In this case, the PUK code needs to be unlocked, but the user does not know the PUK code. Go to the business hall for decoding processing.
The user must not try to input the PUK code. Otherwise, if the error is entered 10 times, it will enter the permanent lock state. There is no way to unlock it. At this time, only go to the business hall to apply for the replacement card. PUK code is not a phone lock is a card lock, and the phone does not matter! SIM card PIN code, PIN2 code, PUK code and PUK2 code four kinds of password relationship All mobile users SIM card password is divided into PIN code, PIN2 code, PUK code and PUK2 code a total of four, the initial code of these four passwords are It is provided by the operator who provides the SIM card. The relationship between the four passwords is as follows: The PIN code (PIN1) is the personal identification number of the SIM card. If not modified by the user, the original password set by the operator is 1234 or 0000.
If the power-on PIN code is enabled, the 4-digit PIN code must be entered after each power-on. The PIN code can be modified to protect your SIM card from being used by others. It should be noted that if the PIN code is entered incorrectly three times, the mobile phone will automatically lock the card and prompt to enter the PUK code to unlock. At this time, it is close to the dangerous edge. Therefore, if you modify the PIN code without authorization, you must keep in mind. The PUK code (PUK1) consists of 8 digits, which cannot be changed by the user. When the mobile phone PIN code is locked and prompted to enter the PUK code, do not act rashly, because the PUK code has only 10 input opportunities, and if 10 errors are entered, the SIM card will be permanently locked, that is, scrapped.
The PUK code of some SIM cards is attached to the card when the user purchases the card, such as China Mobile's Shenzhouxing, and the other part needs to be requested from the network operator. If your PIN code is locked and you don't know the PUK code, don't just enter it. The correct way to do this is to call the service hotline of the SIM card operator. After a simple user data check, you can get the PUK code. Unlock the phone lock, the service is free.
The phone shows that the PIN code is locked, please enter the PUK code.The PUK code is composed of 8 digits and cannot be changed. When the mobile phone PIN code has been locked, prompting to input the PUK code, don't just lose it, because the PUK code has only 10 chances, if 10 times are wrong, the SIM card will be permanently locked, which becomes the fee card. Here are some ways to do this:
Method / step
If the mobile phone card is a Unicom card or a telecom card, then when you buy the card, there is a PUK code on the SIM card. If you save the card, it is very convenient to know the PUK code. (If it is a mobile card, Xiaobian does not see the PUK information on the card, the method is still there)
If you didn't save the card, (it wasn't used to open an account earlier), there is no way.
4 Whether it is Mobile Unicom or Telecom, you can get the PUK code by calling customer service, use another (corresponding network) mobile phone, hit the artificial station (or go to the corresponding business hall), and provide the mobile phone number, identity name, ID card number. Customer service will send you PUK. (Mobile: 10086 Unicom: 10010 Telecom: 10000)
If the number of PUKs is used up, the card is locked, and only the card is added to the business hall, but the information and phone book contacts in the card are gone.
The PIN2 code is used when setting the mobile phone billing. If you enter the error three times, the phone will need to be unlocked with the PUK2 code. The process is the same as the PIN code and PUK code introduced earlier. However, these two passwords are related to the modification of the network billing and the internal data of the SIM card, so they will not be disclosed, and even if the PIN2 password is locked, it will not affect the normal use of the mobile phone. Therefore, the PIN2 code and the PUK2 code do not have to be deliberately ignored.
