PIN Code Request: When the PIN code
request feature is set, you must enter
your PIN each time you switch the phone
on. Consequently, any person who does
not have your PIN cannot use your phone
without your approval. Take extra care
when using this feature as it could lock
your SIM card.
Note: Before setting the PIN code request
feature to Off, you must enter your PIN.
Default PIN values: PIN1 is 1111 and PIN2
is 2222.
Important: Please take note of your
default PIN code. If the PIN code is entered
incorrectly 3 times, the SIM will be locked
and the phone will not be usable. Once the
SIM is locked, it won't be unlocked even
if you try to use it on another phone. The
phone will prompt to ask for PUK Code.
Do not attempt to guess the code, it may
permanently lock your SIM card. Please
contact the operator for further assistance.
