■ 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.
