What is a SIM card
When registering your mobile phone number, you will have a SIM card
(Subscriber Identity Module) provided by the network operator.
The SIM card has information reserved for your use. It includes your
phone number, PIN (Personal Identification Number), PUK (password to
unlock PIN), IMSI (International Mobile Subscriber Identity) number,
network information, phone book data, SMS data and so on. If it is lost,
contact your network operator immediately for help.
PIN code
PIN is the 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
switched on. You can deactivate this feature but risk unauthorized use of
the phone. Some network operators do not permit deactivating the
control.
Note: If you enter the PIN incorrectly three times in a row, the SIM card
will be locked. Please contact your network operator immediately for
decoding. Attempting to decode by you may result in the permanent
failure of the SIM card.
PUK code
PUK (Personal Unblocking Key, 8-digit) unlocks a locked PIN. If you
enter the PUK incorrectly ten times in a row, the SIM card will become
invalid. Please contact your network operator for a new SIM card.
