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 op-
erating in the Home System.
In areas where your Carrier has Roaming agreements,
your phone will display a steady “
Rm ” indication. 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 Selection in
order to obtain service. If your display indicates “
”, you
are in an area where there is no cellular service.
