Fixed dialling
Select Menu > Communic. > Contacts > Options > SIM
contacts > Fixed dial contacts.
With the fixed dialling service, you can restrict calls from your
device to certain phone numbers. Not all SIM cards support
the fixed dialling service. Contact your service provider for
more information.
When fixed dialling is activated, calls may be possible to the
official emergency number programmed into your device.
1. To restrict calls from your device, select Options > New
SIM contact and enter the contact name and phone
number to the list of numbers to which calls are allowed,
or select Add from Contacts to copy the contact from
Contacts. To restrict calls by a country prefix, enter the
country prefix in the list of numbers. All phone numbers
to which calls are allowed must start with this country
prefix.
2. Select Options > Activate fixed dialling. You need your
PIN2 code to activate and deactivate fixed dialling or edit
your fixed dialling contacts. Contact your service provider
if you do not have the code. To cancel the service, select
Options > Deactivate fixed dialling.
Tip: To send text messages to the SIM contacts while
the fixed dialling service is active, you need to add the
text message centre number to the fixed dialling list.

Certificate management.
Digital certificates are used to verify the origins of software
but do not guarantee safety. There are four different types of
certificates: authority certificates, personal certificates,
trusted site certificates, and device certificates. During a
secure connection, a server may send a server certificate to
your device. Upon receipt, it is checked through an authority
certificate stored in your device. You receive notification if
the identity of the server is not authentic or if you do not have
the correct certificate in your device.
Download a certificate from a web site, or receive a certificate
as an e-mail attachment, or as a message sent through a
Bluetooth or infrared connection. Certificates should be used
when you connect to an online bank or a remote server to
transfer confidential information. They should also be used
if you want to reduce the risk of viruses or other malicious
software, and to check the authenticity of software when you
download and install software to your device.
Tip: When you add a new certificate, check its
authenticity.

You can only be sure of the correct identity of a server when
the signature and the validity period of a server certificate
have been checked.
