Preferred Roaming List (PRL)

A database residing in a code division multiple access (CDMA) device that contains the information the device needs to obtain service outside of the device's home network. Information in the PRL includes but is not limited to, service provider identifiers and the radio frequency bands over which the device scans for alternative service providers. In Itron cell relays, the activation process updates the PRL after the cell relay is installed or relocated.
