SIM services
14 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.
