Public system selection
When your phone leaves its home system, it is roaming. Like
other public systems, your home system is either type A or B.
When your phone is roaming, it can search for home-type
systems (same type as your home system) or non-home-
type systems (opposite type as your home system).
Also, your service provider has programmed a list of preferred
systems into your phone. These are systems with which your
service provider has roaming agreements.

Any system When service is not available in your home
system, the phone searches for a preferred system of either
type, then a home-type system, then a non-home-type
system.
Home type When 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 only, preferred first (home system is not used).
Home only The phone uses its home system only (that is, it
will not roam).
