A technician is troubleshooting a company-owned smartphone that is experiencing poor connectivity when users travel internationally. The device, which uses a SIM card, fails to reliably connect to partner networks. To resolve this, the technician needs to ensure the phone has the most current information for roaming. Which of the following actions should the technician take?
Update the Preferred Roaming List (PRL) on the device.
Reset the network settings to factory defaults.
Install the latest carrier settings update.
Manually select a network from the device's network settings.
Installing the latest carrier settings update provides the device with the most recent configuration data from the carrier, including information on roaming agreements and preferred networks. This directly addresses issues with connecting to partner networks while traveling. Updating the Preferred Roaming List (PRL) is incorrect because PRL is associated with legacy CDMA networks, whereas devices with SIM cards operate on GSM-based networks like LTE and 5G. Manually selecting a network is only a temporary solution and does not fix the underlying configuration issue. Resetting network settings is a more drastic step that might not install the latest carrier-specific roaming data.
