In addition to the functions that are available on the phone, your SIM
card may provide additional services that you can access in Menu 10.
Menu 10 is only shown if it is supported by your SIM card. The name and contents of the
menu depend entirely on the service available.
Note: For availability, rates and information on using SIM services, contact your
SIM card vendor.
You can set the phone to show you the confirmation messages that are sent between your
phone and the network when you are using the SIM services by selecting the option Yes
Confirm SIM service actions in Phone settings.
Note: Accessing these services may involve sending a text message (SMS) or
making a phone call for which you may be charged.
