How can I find the PIN2 code and PUK2 code of the mobile phone?

PIN 2 (Personal Identification Number 2) is a personal identification code that needs to be entered when entering a special function (such as setting a fixed number, setting up call billing, etc.). This password is confidential and cannot be accessed by ordinary users, so the operator will not provide it to users and cannot be queried.

PUK2 code is specially used to unlock the PIN2 code that is locked, and PUK2 code is the same, PUK2 code is also 10 times to enter, after continuous input error, PIN2 code will be rejected, the relevant functions of this SIM card can not be used and restored (unless a SIM card is changed), but other functions are not affected. Since it has been said earlier that the pin2 code does not work, then the puk2 code will naturally not come in handy.

The SIM card password has PIN 1 and PIN 2 codes. The PIN is usually referred to as PIN 1, which is used to protect the security of the SIM card. The pin2 code is related to the billing and the modification of the internal information of the SIM card, and the billing function is completed by the mobile phone and the network, such as the deduction of the stored value card, so the pin2 is not public.

Even if pin2 is locked, it will not affect the normal call.

The PUK2 code is the unlock code of the PY2 code, if the PY2 code is entered incorrectly three times, the mobile phone needs to be unlocked with the PY2 code. If it is a Unicom card, purpose.

The former Unicom company does not have the corresponding services related to the functions of the PIN2 code and the PUK2 code for the time being, and it will not affect your normal call and use. Sound.

About the pin2 password you go to the business hall to ask, those customer service mm is not known, they will say that there is only a pin code, pin2 code is not checked, in fact, I know a way to view, hehe! Now my mobile phone uses this function, and after the fixed dial is turned on, I can only surf the Internet, ** and text messages can't be sent. Beg.

The PIN of China Unicom's mobile phone card is a password used to protect the security of the SIM card. PIN codes are divided into pin1 and pin2, and the pin we usually talk about refers to pin1. (The initial value of the PIN code is generally 1234, which can be changed, please refer to the mobile phone manual for specific functions and operations).

Tips: 1. When the PIN code is entered incorrectly 3 times, the SIM card will be automatically locked. At this time, you can check the PUK code information through the "China Unicom APP" (My Unicom - Security Center - My PUK Code) or go to the business hall to check the PUK code information, and enter the PUK code to unlock it.

2. There are 10 chances to enter the PUK code, more than 10 times, the SIM card will automatically start the self-destruct program, so that the SIM card is invalid, then only to the business hall to replace the card.

Mobile phone PIN code:

PIN code (PIN1), a personal identification password for a SIM card. The PIN code of the mobile phone is a security measure to protect the SIM card, to prevent others from stealing the SIM card, if the boot PIN code is enabled, then you have to enter the 4 to 8-digit PIN code after each boot.

pin2 code:

The pin2 code is a personal identification code that needs to be entered when entering a special function (such as setting a fixed number, setting up call billing, etc.).

The PIN 2 code is the password of the SIM card, but it is related to the network billing and the modification of the internal information of the SIM card, so the operator does not disclose the PIN 2 code to the customer.

The "billing" function on the mobile phone is used to cooperate with the network to complete the relevant billing functions, so the pin2 code is confidential.

Ordinary customers don't need to pay attention to the pin2 code. Even if the pin2 code is locked, it will not affect the normal call of the mobile phone. The initial state of the mobile phone PIN 1 code and PIN 2 code is off.

The steps to query the PIN code are as follows:

1.Open the mobile phone handheld business hall and click "My" in the lower right corner, as shown in the red box in the figure below;

PIN code: PIN code is also PIN 1 code, the initial password of mobile and Unicom is 1234, if you change it, please be sure to remember, in case you forget or are locked, unlocking is not so simple! First of all, it depends on which network you are into, and I will introduce them one by one:

Users who join China Mobile Global Pass (i.e. users): If the above users have forgotten the PIN code, it doesn't matter, because the corresponding unlock code PUK can be queried by dialing 1860, and then entering the mobile phone to unlock! Users who join China Mobile Shenzhouxing (i.e., 136 ......, i.e. the fourth digit is not 0):

When you buy a SIM card (that is, when you buy a card number), there is a SIM card when you open it, and there is also a user password card, there is a PUK code on it, when your mobile phone is locked, as long as you find the user password card, scratch the tin coating on it and there is a PUK unlock code, just enter it to unlock. But remember that this user password card is as important as the ID card, like if your card is broken in the future, you have to buy a new card (the number remains the same), and you have to rely on this card to find the PUK code. For example, if the user password card is missing, it is useless to call 1860, because they do not have the customer's user information in the computer there, so they can't find your PUK code.

In other words, if your PIN is locked and you can't find your user password card, your SIM card is useless and the money in the card is wasted! Users who enter China Unicom (i.e., users): This is the same situation as users who enter China Mobile Shenzhou, and I won't say more, the same is to keep their user password card!

Both PIN and PIN 2 are provided by the network operator. So this has nothing to do with the phone, and of course you can't find it in the manual! Secondly, I will talk about the problem of 3 passwords in the phone (ie:

Mobile password, PIN code and PIN 2 code), if you have one of the passwords locked or forgotten in the future, you know who to look for!

1. Pin2 code is the password of the SIM card.

2. The pin2 code is related to the billing of the network and the modification of the internal information of the SIM card, so the pin2 is not public, that is, it does not support self-service query for the time being.

3. Even if the pin2 code is locked, it will not affect the normal call.

PIN code: for personal identification password, the unified initial password is 1234, but if the SIM card PIN code is enabled, the wrong PIN password will be locked if you enter the wrong PIN password three times in a row after booting, and the PUK code is required to unlock, and the customer can go to the business hall for free unlocking, and the unlocked password is still the initial password 1234.

PUK code: is the unlock password of the PIN code, when the mobile phone PIN code is locked, enter the PUK code to unlock, enter the error code ten times in a row, the SIM card will be permanently locked and automatically scrapped.

First, the subject is different.

1. PKU code: It is the PIN unlock code, which is used to unlock the SIM card when the SIM card is entered incorrectly, resulting in the phone being locked.

2. PIN code: It is the personal identification password of the SIM card.

Second, the number of digits is different.

1. PKU code: composed of 8 digits.

2. PIN code: composed of 4 digits, if the boot PIN code is enabled, then enter the PIN code after each boot.

Third, the characteristics are different.

1. PKU code: PUK code only has 10 opportunities to enter, and if the input is wrong 10 times, the SIM card will be permanently locked, that is, scrapped.

2. PIN code: When the PIN code is entered incorrectly three times, the mobile phone will automatically lock the card, and the PIN code is a security measure to protect the SIM card to prevent others from stealing the SIM card.
