A technician is troubleshooting a mobile device that is failing to connect to the correct cellular tower when roaming domestically. The technician discovers the device uses a CDMA network. Which of the following should the technician update to resolve this issue?
The Preferred Roaming List (PRL) is a database on a CDMA (Code Division Multiple Access) device that tells it which networks and towers to connect to, and in what order of priority. Updating the PRL is a common troubleshooting step for domestic roaming issues on CDMA networks, as it ensures the device has the latest information on available partner networks. An operating system (OS) update addresses the phone's core software and features, not its cellular roaming priorities. A Product Release Information (PRI) update modifies radio settings like network and country codes, but the PRL specifically governs the selection of roaming partners. International roaming settings are not relevant for a domestic connectivity issue.
