■ Browser security

Security features may be required
for some services, such as online
banking or 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 improves
security services for applications
requiring a browser connection, and
allows you to use a digital signature.
The security module may contain
certificates as well as private and
public keys. The certificates are
saved in the security module by the
service provider.
To view or change the security
module settings, select
Settings > Security
module settings.

Certificates

Important: Even if the use
of certificates makes the
risks involved in remote
connections and software
installation considerably
smaller, they must be used
correctly in order to benefit
from increased security. The
existence of a certificate
does not offer any
protection by itself; the
certificate manager must
contain correct, authentic,
or trusted certificates for
increased security to be
available. Certificates have
a restricted lifetime. If
Expired certificate or
Certificate not valid yet is
shown even if the certificate
should be valid, check that
the current date and time in
your device are correct.
Before changing any
certificate settings, you
must make sure that you
really trust the owner of the
certificate and that the
certificate really belongs to
the listed owner.
