Enhanced Roaming

Cellular systems are identified by a number called System Identifier or SID.Your phone is equipped with a Preferred Roaming List (PRL) which can be programmed by your Carrier to take advantage of the families of cellular system (SIDs) that your Carrier owns, or has special billing ar- rangements with, in different cities.

In your Home System Area, both “No Service” and “Rm” are off in your display. Outside of the Home System in Ser- vice Areas closely associated with your Carrier, the phone’s display may appear the same as when operating in the Home System.
