What should I do if I forget my mobile phone PIN?

You can modify the pin code (click Settings-Set sim Card Lock-Change the PIN code of the sim card) to protect the security of the sim card. If the PIN code is enabled, a PIN code consisting of 4-8 digits must be entered after each boot, and the original password set by the operator is 1234 or 0000.

The pin code was entered incorrectly for three times, and the SIM card has been disabled. It is suggested that we need to enter the puk code. We can reset the pin code by getting the puk code.

Step 1: Log in to China Mobile official website, enter the mobile phone number, select the service password of the login method (because the sim card is locked and cannot receive the dynamic verification code), and click Login.

After logging in to your personal account, select "Common Query" in the left column and use PUK code to query, as shown in the following figure:

Your PUK code is: * * * * *

Finally, enter the queried PUK code, and then prompt "Enter a new PIN code", so that you can enter the familiar mobile phone interface by resetting the PIN code.

1. What is a PIN?

There are four kinds of SIM card passwords: PIN code, PIN2 code, PUK code and PUK2 code. The initial codes of these four types of passwords are provided by the operators who provide SIM cards, which are closely related to us, namely PIN code (PIN 1) and PUK code (PUK 1). If you enter the wrong PIN code for three consecutive times, the mobile phone card will automatically lock the card and prompt you to enter the PUK code to unlock it.

Second, the method of changing the password.

1, the PIN code can be modified to protect the security of the SIM card. If PIN code is enabled, you must enter a PIN code consisting of 4-8 digits after each startup. The original password set by the operator is usually 1234 or 0000.

PIN code modification method: Click Settings-Set SIM Card Lock-Change SIM Card PIN.

2. The 2.PIN code was entered incorrectly for three times, and the SIM card has been deactivated, which indicates that we need to enter the PUK code. By getting the PUK password, we can reset the PIN code, so how do we get the PUK password?

(1) Step 1: Log in to China Mobile official website, enter the mobile phone number, select the service password of the login method (because the SIM card is locked and cannot receive the dynamic verification code), and click Login.

(2) After logging in to your personal account, select "Common Query" in the left column and use PUK code to query, as shown below:

Your PUK code is: * * * * *

(3) Finally, enter the inquired PUK code, and then prompt "Enter a new PIN code", so that you can enter the familiar mobile phone interface by resetting the PIN code. However, if you forget the PIN code and service password of the mobile phone SIM card, you can't go to the official website to inquire about the PUK code, so you can only go to the mobile business hall to inquire about the PUK code.

Third, other methods

If the above two methods can't be solved, please bring the owner's ID card, mobile phone license (letter of introduction or company official seal issued by company customers) as soon as possible, or bring the SIM card to the business hall to find customer service. Provide the latest call record number or mobile phone bill, invoice, etc. Until the mobile phone business hall learned that the PIN code service was unlocked, and unlocking the PIN code was free.

The above are the specific methods and steps to retrieve the PIN code of the SIM card of the mobile phone. Is it very simple for a friend in need to follow the above method? Now, you don't have to worry about what to do if you can't remember the PIN code. It is worth noting that since we know that PIN code is very important to our mobile phone card, we should pay special attention to PIN code. If we accidentally lose the cardholder's information, we must modify the PIN code and PUK code at the first time to avoid being used by thieves after loss.
