nRF9160 %XCOUNTRYDATA command

Hello,

Does the modem perform a general scan on all bands to determine the MCC of the first signal detected and then limit the search to the values in %XCOUNTRYDATA as it continues?

The modem will prioritize the bands set by the XCOUNTRYDATA command.

What happens when the modem power cycles?  Upon power up, does the modem always revert to the last known network, and if not found, then jump all the way back to the beginning and starts a general scan?

It will first scan for the band that was previously connected to, then it will move on to other bands until successful connection.
