Notes:
• Using the phone in a city where you do not sub-
scribe to a cellular service is referred to as
roaming . See “Roaming” on Page 45.
• The designation (A or B) that appears with the
setting is based on the selected phone num-
ber’s NAM.
• Usually, it is less expensive to use the same
provider type for cellular service when you are
in your home city and when you roam. To do
this, you need to know whether your cellular
service provider is type A or B in your home city
and in each city where you plan to travel.
• It is possible for a cellular service provider to be
(or have agreements with) Provider A in some
cities and Provider B in others.
PREFERRED — Your dealer can program a list of
“preferred” networks into your phone (which in-
cludes your home system). If so, your phone tries to
use the home system, then the strongest available
network in this list. If not, the phone will try to use a
network that is the same type (A or B) as your home
system. Check with your dealer to see if your phone
has been programmed with a list of preferred net-
works to use. You can still choose this option even if
your phone has not been preprogrammed; that way
