Module PIN request—Select On to set the phone to ask for the module PIN when
using services provided by the security module.
Change module PIN—Change the module PIN, if allowed by the security module.
Change signing PIN—Select the signing PIN that you want to change, enter the
current PIN code; then enter the new PIN code twice.
Digital signature
You can make digital signatures with your phone if your SIM card has a security
module. The signature can be traced back to you through the private key on the
security module and the user certificate that was used to perform the signature.
Using the digital signature can be the same as signing your name to a paper bill,
contract, or other document.
1 While browsing, select a link on a page, such as the title of the book you want
to buy and its price.
The text to sign (possibly including amount, date, etc.) is shown.
2 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. Do not
enter any personal data such as your signing PIN.
3 Read all of the text before signing, scrolling through the text if necessary.
4 To sign the text, select Sign.
5 Select the user certificate you want to use, enter the signing PIN (provided
with the SIM card if the SIM card has a security module), and select OK.
The digital signature icon disappears, and the service may display a
confirmation of your purchase.
Cache memory
The information or services you access with the browser are temporarily saved in the
cache memory of the phone. A cache is a buffer memory that is used to store data
temporarily.
If you tried to access or have accessed confidential information requiring
passwords (for example, your bank account), clear the cache after each use.
To clear the cache from the menu, select Services > Clear the cache.
To clear the cache while browsing, select Options > Other options >
Clear the cache.
