■ Security
When security features that restrict calls are in use (such as call restriction, closed user
group, and fixed dialing) calls still may be possible to the official emergency number
programmed into your device.
Select Menu > Settings > Security and from the following options:
PIN code request and UPIN code request — to set the phone to ask for your PIN or UPIN code
every time the phone is switched on. Some SIM cards do not allow the code request to be
turned off.
Call restrictions — to restrict incoming calls to and outgoing calls from your phone (network
service). A restricting password is required.
Fixed dialing — to restrict your outgoing calls to selected phone numbers if this function is
supported by your SIM card.
Closed user group — to specify a group of people whom you can call and who can call you
(network service).
Security level > Phone — to set the phone to ask for the security code whenever a new SIM
card is inserted into the phone. If you select Memory, the phone asks for the security code
when the SIM card memory is selected, and you want to change the memory in use.
Access codes — to change the security code, PIN code, UPIN code, PIN2 code, or
restricting password.
Code in use — to select whether the PIN code or UPIN code should be active.
PIN2 code request — to select whether the PIN2 code is required when using a specific phone
feature which is protected by the PIN2 code. Some SIM cards do not allow the code request
to be turned off.
Authority certificates or User certificates — to view the list of the authority or user
certificates downloaded into your phone. See ”Certificates,” p. 34.
Security module settings — to view Security module details, to activate Module PIN request,
or change the module PIN and signing PIN. See also ”Access codes,” p. 8.
Secure element — to allow the access of an external NFC reader to the secure element
without confirmation, with confirmation or with passcode. To change the secure element
passcode select Change passcode. See also ”Payment and ticketing,” p. 63.
■ Phone software updates
Your service provider may send phone software updates over the air directly to your device.
This option may not be available, depending on your phone.
Warning: If you install a software update, you cannot use the device, even to make
emergency calls, until the update is completed and the device is restarted. Be sure
to backup data before accepting a software update.
