In each cellular service area there are usually two cellular operators operating public systems of type “A” or “B”. One of the public systems (A or B) is your home system (depending on your operator) but your phone can work with both types of systems. With Menu 7, you can select the type of system the phone should use.
(If you have registered with several operators, use Menu 8, NAM SELECT, to select a NAM. This determines which phone number and “home system” the phone uses.)
Both A&B means that when roaming, the phone first tries to use a
Hometype A or Hometype B means the phone tries
to use only a
Home Area means the phone cannot roam at all.
Note: To use this option, your home system operator must have a roaming agreement with the host company whose system you try to use. Contact your home system operator for the roaming agreements they have with other operators.
Depending on the selection either the A or B indicator (or both) will appear. Neither indicator appears if Home Area is selected.
Roaming Indicators in Public Systems
When the phone begins roaming, it beeps, displays ROAMING, and lights the roaming indicator (
). For a description of the two states of the roaming indicator, see “Keys and the Display”, page ii. Some cellular systems can recognize a roaming phone automatically. In other systems, you must contact the cellular operator before the system can recognize the phone. You will need to give your phone number, your phone’s ESN (electronic serial number), and how you plan to pay for your calls. There is usually an additional charge for roaming calls.
