■ Access codes
Lock code
The lock code (5 to 10 digits) helps to protect your phone against unauthorized
use. The preset code is 12345. Change the code, and keep the new code secret and
in a safe place separate from your phone. To change the code and to set the phone
to request the code, see “Security,” p. 73.
If you enter an incorrect lock code five times in succession, the phone ignores
further entries of the code. Wait for 5 minutes, and enter the code again.
When the device is locked, calls may be possible to the official emergency number
programmed into your device.
PIN codes
The personal identification number (PIN) code and the universal personal
identification number (UPIN) code (4 to 8 digits) help to protect your SIM card
against unauthorized use. See “Security,” p. 73. The PIN code is usually supplied
with the SIM card.
The PIN2 code (4 to 8 digits) may be supplied with the SIM card and is required for
some functions.
