Certificates

Authority certificates can either be saved in the security module by the SIM card issuer or service
provider, or they can be downloaded from a WAP page and be saved in the phone's memory or on the
SIM card. User certificates are saved in the security module by the SIM card issuer or the service
provider. Server certificates are not saved.

service settings) is encrypted.
It is up to the service provider to secure the data transmission between the gateway and the
content server.

Authority certificates are used by some WAP services, such as banking services, for checking
