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.

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

To set the phone to show you the confirmation messages sent between your phone and the
network when you are using the SIM services, select Menu > Settings > Phone > Confirm
SIM serv. actions > Yes.
Accessing these services may involve sending messages or making a phone call for which
you may be charged.
