Digital signatures

You can make digital signatures with your Vertu phone if your SIM card has a security
module. Using a digital signature is similar to signing your name to a paper bill,
contract, or other document.
NOTE: You need to know your signing PIN to make digital signatures. If this
is not provided with your SIM card, contact your service provider for further
information.
To make a digital signature:
1. 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.
2. Check that the header text is Read, and that the digital signature icon (
is displayed. If the digital signature icon does not appear, there is a security
breach and you should not enter any personal data, including your signing PIN.
3. Read all of the text. The text may not fit within a single screen so you may need
to scroll through it.
4. Select Sign.
5. Select the user certificate to sign with.
6. Enter and confirm the signing PIN. The digital signature icon disappears, and the
service may display a confirmation.
