•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.

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
