What is a SIM card ?
While registering your mobile phone number, you will be provided with a
SIM card (Subscriber Identity Module) by your network operator.
The SIM card has information, such as phone number, PIN (Personal
Identification Number), PIN2, PUK (PIN Unlocking Key is the password to
unlock PIN), PUK2 (password to unlock PIN2), IMSI (International Mobile
Subscriber Identity) number, network information, phone book data, SMS
data and so on reserved for your use. If it is lost, contact your network
operator immediately for help.
PIN Code
PIN is usually a 4 digit password provided by your network operator. It is
usually 4 digits. When you input the PIN code, the screen displays “*” to
replace the number entered.
PIN is used to access the SIM card. If the PIN protection function is
enabled, the screen will display “Enter PIN” each time the phone is
switched on. You can deactivate this feature but this may result in the
unauthorized use of the phone. Some network operators do not permit
deactivating the control.
PIN2 Code
PIN2 is required for some specific functions provided by the network, such
as the charge information.
