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 is shown, 
which may include the amount and 
date.
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 
OK
. 
The digital signature icon 
disappears, and the service may 
display a confirmation of your 
purchase.
