Access Codes

You can use the access codes described in this section to avoid un-
authorised use of your phone and SIM card.
The access codes (except PUK and PUK2 codes) can be changed by
using the menu 4-3-5. See the next section.
Security Code (5 digits)
The security code can be used to avoid unauthorised use of your
phone, see 'Phone Security' (menu 4-3-4). The factory setting for
the security code is 12345. Change the code, see 'Security settings
- Change Access Codes'. Keep the new code secret and in a safe
place, separate from the phone.
PIN Code (4 to 8 digits)
The PIN (Personal Identification Number) code protects your SIM
card against unauthorised use. The PIN code is usually supplied with
the SIM card.
PIN2 Code (4 to 8 digits)
The PIN2 code, supplied with some SIM cards, is required to access
some functions, such as charging unit counters. These functions are
only available if supported by your SIM card.
PUK Code (8 digits)
The PUK (Personal Unblocking Key) code is required to change a
blocked PIN code. The PUK code may be supplied with the SIM card.
If not, contact your local service provider for the code. If you lose
the code, contact your service provider.
PUK2 Code (8 digit)
The PUK2 code, supplied with some SIM cards, is required to change
a blocked PIN2 code. If you lose the code, contact your service pro-
vider.
