Security code
settings
Your device has a security option
allowing you to lock your phone with a
PIN code. When the PIN code is set and
turned on, no outgoing calls are
allowed and the menu cannot be
accessed without entering the correct
code first. This prevents unauthorised
outgoing calls or access to any
information stored on your device.
The PIN code option is in the Settings
menu. The first time you access the
Security option, you must enter a PIN
code. The default PIN code may vary
depending on your wireless service
provider or network operator who
provided your UIM card.
The PIN code protects the UIM card
from unauthorised access. The PIN
code can be 4–8 digits in length.
After three successive incorrect
entries, the PIN code is blocked.
You need to enter the personal
unblocking key (PUK) code.
See "Personal unblocking key (PUK)
code", p. 57.
