 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 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.
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.
If the digital signature icon does not appear, there is a security breach, 
and you should not enter any personal data such as your signing PIN.
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 (see 
Access codes p. 8), and select OK. The digital signature icon disappears, 
and the service may display a confirmation of your purchase.
15. 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.
For availability and information on using SIM card services, contact your SIM 
card vendor. This may be the service provider, network operator, or other vendor.
