■ Browser security
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.
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.
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.
To sign the text, read all of the text first, and select Sign.
The text may not fit within a single screen. Therefore, make sure to scroll through 
and read all of the text before signing.
Select the user certificate you want to use. Enter the signing PIN. The digital 
signature icon disappears, and the service may display a confirmation of your 
purchase.
14. SIM services
Your SIM card may provide additional services. You can access this 
menu only if it is supported by your SIM card. The name and 
contents of the menu depend on the available services.
Accessing these services may involve sending messages or making a phone call for 
which you may be charged.
15. PC connectivity
You can send and receive e-mail, and access the internet when your phone is 
connected to a compatible PC through a Bluetooth or a data cable connection.
