What is a SIM card passcode?
The SIM card password is the PIN code, which is the password that needs to be entered to use the SIM card, that is, the personal identification password of the SIM card, which is the security setting for the SIM card provided by the operator.
Generally speaking, the first time you use a PIN code, you need to enter the original password of the PIN code "1234", when the PIN code is set, the phone will automatically prompt you to enter the PIN code to unlock each time you boot.
Why set a PIN?
The main purpose of setting up a PIN code is that when your mobile phone is lost or stolen and you do not report the loss of the SIM card in time, criminals will not be able to obtain the personal information and personal property in the mobile phone through the weak verification method of "mobile phone number + verification code".
