Send own number
Use Menu 4 1 3 to access this network service, which allows
you to display your phone number to the person you are
calling. This feature is only effective when calling a number
that is equipped with Caller ID.
Preset uses the default network setting (on or off). Contact
your service provider to find out what the default is.
On displays your number to people you call.
Off prevents your number from being shown to people you
call.
