0 - No preference. Initial system selection is based on history data and USIM
1 - LTE-M preferred
2 - NB-IoT preferred
3 - Network selection priorities override system priority, but LTE-M is prefered
4 - Network selection priorities override system priority, but NB-IoT is prefered
For details look at "nRF9160 AT Commands Command Reference Guid" from Nordic,
