Analog system selection
In each analog service area there are usually two service
providers. The service provider you sign up with, also known
as your home system, is of type A or B. Systems that are of
the same type as your home system are called “home-type”
systems; systems that are of the opposite type as your home
system are called “non-home-type” systems.

Your service provider may have programmed a list of
preferred systems into your SIM card. Your phone may
search for systems in this list when service is not available
in your home system.
The analog system selection feature allows you to request
the order in which your phone looks for available systems.
Choosing a system-selection method
Use Menu 4 4 2 to tell your phone how to select analog
systems.
Note: Using Home only or Pref. system is usually the most
economical choice.
Pref. system If service is not available in your home
system, the phone searches for a preferred system of type A
or B, then a home-type system, then a non-home-type
system.
Home type If service is not available in your home system,
the phone searches for a home-type system, preferred first.
Nonhome type The phone searches for a non-home-type
system, preferred first.
Home only The phone uses its home system only (that is, it
will not roam).
Note: In some areas, the wireless system automatically
recognizes roaming phones. In other areas, you need to
contact the service provider before the system can recognize
your phone. The operator needs to know your phone number,
your phone's IMEI or your analog module’s SN (serial number),
and how you plan to pay for your calls. There is normally an
additional charge for roaming calls.
Your phone’s IMEI is located on the back, under the battery.
Your analog module’s SN is located on the back of the
module. Your IMEI/SN can normally be read over the air by
roaming wireless service providers when you call them to
register your roaming presence on their wireless network.
