13.SIM services
Your wireless service provider may provide additional services that are
available in Menu 12 of your phone. Menu 12 appears only if supported
by your service provider and SIM card. The name and contents of this
menu depend entirely on the services available. Any questions about
service availability, rates, and instructions must be directed to the
company that sold you your SIM card.
You can set the phone to display confirmation messages sent between
your phone and the network when you are using SIM services by pressing
Menu 4-3-7 (Notifications on SIM update), and choosing
Shown.
Note: Accessing these services may involve sending a text message (SMS)
or making a phone call, for which you may be charged.
