What should I do if I forget the startup pin lock screen password of my HTC one s phone? Please guide me! grateful!

There are several passwords for mobile phones. One is the service password, which is generally 6 digits by default, "000000" or the last 6 digits of the mobile phone number. It is used when logging into the service provider's website to query personal information; the other is the SIM card lock password (pin code and puk code). The default is usually 8 digits, which is used to prevent the phone from being lost and causing loss of phone bills; there is also the lock screen password (also called the pin code), which is usually four digits by default, 1234 or 0000, to prevent outsiders from peeking at the phone screen content; and other security Password, such as factory reset password, etc.

You must figure out what password the mobile phone requires, and then you can prescribe the right medicine.

1. If you enter the wrong pin code of the SIM card three times, the SIM card will be locked. You can only unlock it by entering the PUK code. If you enter the wrong PUK code 10 times, the SIM card will be locked. You can only Go to the service provider to get a new card (it costs 20 yuan to make a new card by phone).

This setting of the mobile phone SIM card is mainly to protect personal mobile communication services and prevent the SIM card from being stolen by others, incurring high fees and causing unnecessary losses to users.

If you want to know the PIN code and PUK code, you can log in to the China Mobile website with your mobile phone number and service password and automatically enter the personal customer webpage. Then find "My Mobile--All Categories (just put the mouse on it)--Other Functions--SIM Card Information Query", where you can see the PIN1/PIN2/PUK1/PUK2 code of your phone. If it is a telecommunications card (number), you can log in to the official website of China Telecom with your mobile phone number and password, and find "Consumer Help Center (in the upper right corner of the screen)--Convenient Services--Convenient Services--Real PUK Code Query--In the box Enter the mobile phone number and the PUK code will be displayed. There are usually two codes, the first is the PUK1 code, and the second is the PUK2 code.

Many SIM cards now have a PUK code on the big card.

2. Electronic products have multiple channels that require PIN passwords to protect personal information. There are generally two unlocking PINs: one is the unlocking PIN code of the SIM card, which is usually a four-digit code, and the default is generally 1234. The main purpose is to prevent the SIM card from being stolen and used by others to waste your mobile phone bill; the second is to unlock the screen PIN, which also prevents other people from entering the mobile phone desktop for access at will to protect your personal information. There are also other security PIN codes. For example, the PIN code for restoring the factory settings of a mobile phone is one of them. The default is usually six zeros. It prevents you from inadvertently restoring your phone to its factory state and losing your personal information on your phone, so it prompts you to enter your PIN

code as a warning when you want to restore it. These codes can be the same or different. Generally, they are set to the same for ease of memory.

3. The default PIN code for mobile phone SIM cards is generally a four-digit password, and the default is "0000" or "1234" or "1111". In order to prevent malicious attempts to gain access, the device sets the number of inputs (generally The default is 3 times). After the number of times is exceeded, the device will be locked or required to enter a PUK code (which is a higher-level eight-digit password). You can also set the PIN code yourself. You must remember it after setting it. Once you forget it, you usually have to go to the after-sales service.

Four. Here is a solution for forgetting the lock screen PIN code: press and hold the power button and volume up button at the same time in the shutdown state, and find the "Restore Factory Settings" item in the pop-up dialog box. Enter recovery. Select Simplified Chinese-Clear Data-Clear User Data, and then restart the system. However, the mobile application software will be retained, but the user data will no longer exist.

Note:

The Sim card PIN has a limit. If you enter it correctly, you can use it an unlimited number of times. Once you enter the wrong PIN three times, even if you find the correct PIN, you will be prompted for an error if you enter it again. It doesn't even prompt an error and directly requires the PUK code to be entered.

Therefore, you must pay attention to the number of times when operating. Never enter the wrong PIN code three times without paying attention, and then continue to enter the wrong PIN code ten times, which will burn the card. Other pins generally have no limit on the number of times.
