When security features that restrict calls are in use
(such as call barring, closed user group, and fixed
dialling), calls may be possible to the official
emergency number programmed into your device. Call
barring and call diverting cannot be active at the same
time.
You need your PIN2 code to activate and deactivate
fixed dialling or edit your fixed dialling contacts.
Contact your service provider for your PIN2 code.
Select Options and from the following:
Activate fixed dialling — Activate the fixed
dialing.
Deactivate fixed dialling — Deactivate the fixed
dialing.
New SIM contact — Enter the contact name and
phone number to which calls are allowed.
Add from Contacts — Copy a contact from the list
of contacts to the fixed dialling list.
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.

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.
You can download a certificate from a web site, or
receive a certificate as a message. 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.
