Searching and Selecting a PLMN
Context
On a WCDMA network or a network downward compatible with the WCDMA network, you can manually select a public land mobile network (PLMN) or configure the device to automatically select a PLMN.
By default, a 3G modem automatically selects a PLMN. If you have subscribed to WCDMA services and obtained a mobile country code (MCC) and a mobile network code (MNC) from a carrier, you can manually select a PLMN. If an incorrect MNC or MCC is selected, the device will display a warning message.
