The proprietary %XCOUNTRYDATA command can be used to configure country-specific search parameters. The list contains access technology, band, and E-UTRA Absolute Radio Frequency Channel Number (EARFCN) to be used. The maximum number of countries is 70. v1.3.x
The information inserted with the %XCOUNTRYDATA command can speed up network selection in a location that is new to the device. The modem uses the information first during network selection when moving to a new area, but performs normal full searches if they are needed to find service. This feature does not break the 3GPP network selection rules defined in 3GPP TS 23.122. The network that is found based on this information must be possible to select according to the 3GPP network selection rules.
This operation is allowed only when the modem is not activated.
