17 SIM services
In addition to the functions available on the phone, your SIM
card may provide additional services that you can access
through the SIM services menu. This menu is shown only if it is supported by your
SIM card. The name and contents of the menu depend entirely on the service
available. For availability, rates, and information on using SIM services, contact
your service provider.
To see the messages sent between the phone and the network when you are using
the SIM services, select Settings > Phone settings > Confirm SIM service
actions > Yes.
Accessing these services may involve sending a text message or making a phone
call for which you may be charged.
