SIM Lock
When the SIM Lock feature is enabled, your phone only
works with the current SIM. You must enter the SIM lock
code to unlock the SIM so you can use a different SIM card.
Once you have entered the lock code, you are asked to
confirm your entry.
FDN Mode (SIM Dependent)
FDN (Fixed Dial Number) mode, if supported by your
SIM card, allows you to restrict your outgoing calls to a
limited set of phone numbers.
The following options are available:
Disable : you can call any number
Enable : you can only call phone numbers stored in the
Address Book. You must enter your PIN2.
Note: Not all SIM cards have a PIN2. If your SIM card does not, this menu
does not display.
Change PIN2 (SIM Dependent)
The Change PIN2 feature allows you to change your
current PIN2 to a new one. You must enter the current
PIN2 before you can specify a new one. Once you have
entered a new PIN2, you are asked to confirm it by
entering it again.
Note: Not all SIM cards have a PIN2. If your SIM card does not, this menu
does not display.
