Setting up WAP and e-mail
Security module (Locks)
The security module is located on the SIM card, if
your network operator or service provider supplies
such a service. It can contain both certificates and
your private keys. The security module is protected
by a special access PIN and your phone asks you
for it when establishing a secure connection.
To enter the access PIN (for the security
module) and the signature PIN
• Scroll to Connectivity, WAP options,
Security, Locks.
Digital signatures
You can sign a contract with your phone by entering a
digital signature PIN as if signing with a pen on paper.
Digital signature records can be traced back to your
private key through a certificate that is used for signing
a contract.
All transactions (signed contracts) made with your
phone when browsing are stored in your phone.
To check your contracts
• Scroll to Connectivity, WAP options,
Security, Contracts.
Trusted certificates and Client certificates
To establish a secure connection when using certain
WAP services, for example banking or WAP shopping,
you need certificates in your phone.
• The different types of certificates are as follows:
1. Server certificates are used to identify a WAP gateway
to the phone and to show that it is certified by a trusted
authority. The server certificate is checked against
trusted certificates that are stored in the phone or in a
security module. If the phone cannot verify the identity
of a server, you are given the option to terminate or
continue the connection.
2. Trusted certificates are used to verify the WAP
gateway that you are trying to connect to. Your
phone may already contain trusted certificates
when you buy it. If you have a security module,
it may also contain trusted certificates. You can
also download trusted certificates from
3. Client certificates are located in a security module
together with your private keys. Client certificates
can be used to present your identity to a bank or
other services. They can also be used for digital
signatures.
