Select from the following:
PIN code request — When active, the code is requested each
time the device is switched on. Deactivating the PIN code
request may not be allowed by some SIM cards.
PIN code, PIN2 code, and Lock code — You can change the
PIN code, PIN2 code, and lock code. These codes can only
include numbers from 0 to 9. Avoid using access codes similar
to the emergency numbers to prevent accidental dialling of
the emergency number. If you forget the PIN or PIN2 code,
contact your service provider. If you forget the lock code,
contact a Nokia Care point or your service provider.
Phone autolock period — To avoid unauthorised use, you
can set a time-out after which the device automatically locks.
A locked device cannot be used until the correct lock code is
entered. To turn off the autolock period, select None.
Lock if SIM card changed — You can set the device to ask
for the lock code when an unknown SIM card is inserted into
your device. The device maintains a list of SIM cards that are
recognised as the owner's cards.
Remote phone locking — Enable or disable remote lock.
Closed user group — You can specify a group of people to
whom you can call and who can call you (network service).
Confirm SIM services — You can set the device to display
confirmation messages when you are using a SIM card service
(network service).

Authority certificates — View and edit authority
certificates.
Trusted site certificates — View and edit trusted site

Personal certificates — View and edit personal certificates.
Phone certificates — View and edit device certificates.
Digital certificates do not guarantee safety; they are used to
verify the origin of software.
Important: Even if the use of certificates makes the risks
involved in remote connections and software installation
considerably smaller, they must be used correctly in order to
benefit from increased security. The existence of a certificate
does not offer any protection by itself; the certificate
manager must contain correct, authentic, or trusted
certificates for increased security to be available. Certificates
have a restricted lifetime. If "Expired certificate" or
"Certificate not valid yet" is shown, even if the certificate
