Configure manual carrier selection

• Automatic—The device automatically selects the carrier based on your SIM and cellular network status.
• Manual—The device will only connect to the carrier identified in the Network PLMN ID. If the carrier is not available, no cellular connection will be established.
• Manual/Automatic—The device will attempt to connect to the carrier identified in the Network PLMN ID. If the carrier is not available, the device will fall back to using automatic carrier selection.

Note You can use the modem scan command at the Admin CLI to scan for available carriers and determine their PLMN ID. See Scan for available cellular carriers for details.

Depending on your device configuration, you may be presented with an Access selection menu. Type admin to access the Admin CLI.
