Security features may be required for some services, such as online banking or 
shopping. For such connections you need security certificates and possibly a 
security module, which may be available on your SIM card. For more information, 
contact your service provider.
Certificates
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 should be valid, check that the current date and time in your device are correct.
Before changing any certificate settings, you must make sure that you really trust the owner 
of the certificate and that the certificate really belongs to the listed owner.
There are three kinds of certificates: server certificates, authority certificates, and 
user certificates. You may receive these certificates from your service provider. 
Authority certificates and user certificates may also be saved in the security 
module by the service provider.
To view the list of the authority or user certificates downloaded into your device, 
select Menu > Settings > Security > Authority certificates or User certificates.
 
 is displayed during a connection if the data transmission between the phone 
and the content server is encrypted.
The security icon does not indicate that the data transmission between the gateway and the 
content server (or the place where the requested resource is stored) is secure. The service 
provider secures the data transmission between the gateway and the content server.
Digital signature
You can make digital signatures with your phone if your SIM card has a security 
module. Using the digital signature can be the same as signing your name to a 
paper bill, contract, or other document.
1. To make a digital signature, select a link on a page, for example, the title of the 
book you want to buy and its price. The text to sign, which may include the 
amount and date, is shown.
Check that the header text is Read and that the digital signature icon 
 is 
shown.
