from your device to certain phone numbers. Not all SIM
cards support the fixed dialling service. Contact your

to the official emergency number programmed into
your device.

 and enter the contact name and

phone number to the list of numbers to which calls
are allowed, or select 

 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.

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.
