Enhanced Roaming

Cellular systems are identified by a number called Sys- tem Identifier or SID.Your phone is equipped with a Pre- ferred Roaming List (PRL) which can be programmed by your Carrier to take advantage of the families of cel- lular system (SIDs) that your Carrier owns, or has spe- cial billing arrangements with, in different cities.

•In your Home System Area, both “” and “ Rm” are not displayed on your phone. Outside of the Home System in Service Areas closely associated with your Carrier, the phone’s display may appear the same as when operating in the Home System.

•In areas where your Carrier has Roaming agree- ments, your phone will display a steady “ Rm” indica- tion. If your display indicates a flashing “ Rm”, you are in a cellular system which is not associated with your Carrier (you can still make or receive calls).

•If your display indicates a flashing “”, you may have to change your A/B System Selection or NAM Selec- tion in order to obtain service. If your display indi- cates “”, you are in an area where cellular service is not available.
