PIN is used to access the SIM card. If the PIN protection
function is enabled, the screen will display “Enter PIN”

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.
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 yourself 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.
