Browser security

Security features may be required for some services, such as banking services
or online 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.

SECURITY MODULE

The security module can contain certificates as well as private and public keys.
The purpose of the security module is to improve security services for applications
requiring browser connection. It allows you to use a digital signature. The
certificates are saved in the security module by the service provider. See also
“Access codes” on page 18.

module. Enter the current module PIN code; then enter the new code twice.
