PIN code (4 to 8 digits)
The PIN (Personal Identification
Number) code protects your USIM card
against unauthorised use. The PIN code
is usually supplied with the USIM card.
When the PIN code request is set to
On, your phone will request the PIN
code every time it is switched on. When
the PIN code request is set to Off,
your phone connects to the network
directly without the PIN code.
PIN2 code (4 to 8 digits)
The PIN2 code, supplied with some
USIM cards, is required to access
functions such as Fixed dial number.
These functions are only available if
supported by your USIM card.
PUK code (8 digits)
The PUK (PIN Unblocking Key) code is
required to unblock a blocked PIN
code. The PUK code may be supplied
with the USIM card. If not, contact your
network operator's customer service
department for the code. If you lose
the code, contact your network
operator's customer service
department.
PUK2 code (8 digits)
The PUK2 code, supplied with some
USIM cards, is required to unblock a
blocked PIN2 code. If you lose the
code, contact your network operator's
customer service department.
Security code (4 digits)
The security code prevents
unauthorised use of your phone. The
default security code is set to '0000'
and the security code is required to
delete all phone entries and to restore
the handset to the factory settings.
