Calling Options (Menu 5 2)
This menu lets you set your phone so that it can only make
the types of calls you specify, or only in certain types of
networks.
Note: When calls are restricted, calls may be possible to
the emergency number programmed into your phone
(e.g., 911 or another official emergency number) including
calls by emergency 9 dialing.
Carrier Selection (Menu 5 2 1)
Your phone uses a carrier network (also called a cellular
system) to make and receive calls. Generally you sign up
for service with a particular "carrier" (your cellular service
provider). This is called your "Home system" and usually
you want the phone to use it.
But there may be times when you can't or don't use your
Home system (for example when you travel). Then, there's
usually more than one network your phone can work in.
But which one should it work in? The point of the Carrier
Selection menu is to help your phone make the best
choice for you.
A simple fact to know: all cellular systems are either type
"A" or "B". So your "Home system" is either an "A" or "B"
system. Ask your cellular service provider or dealer which
type yours is.
