    thanks.

    After many test I discover all stuff.
    This is example at RouterBoard Chateau, RouterOS 7 beta 8

    Quectel EG12 not support frequency lock to select band at any tower.
    Quectel EG12 support one and many Cell Lock’s, you can enter max 20 of CellLock’s and it select the one with the best signal and set it as primary-band.

    EARFCN give us center of frequency specific band of our ISP,
    PHY-CELLID give us a specific antenna at tower

    Example is base at signals like this one, Cell-Monitor show us:

    interface/lte/cell-monitor lte1
    Columns: PHY-CELLID, BAND, EARFCN, RSRP, RSRQ, RSSI, AGE
    PHY BA EARF RSRP RSRQ RSSI AG
    64 B3 1675 -99dBm -10dB -71dBm 1s
    64 B7 3350 -104dBm -8dB -77dBm 1s
    70 B3 1675 -110dBm -20dB -81dBm 1s
    70 B7 3350 -116dBm -19dB -90dBm 1s
    90 B3 1675 -114dBm -20dB -81dBm 1s
    90 B7 3350 -123dBm -20dB -92dBm 7s
    222 B3 1675 -118dBm -20dB -83dBm 4s
    403 B3 1675 -111dBm -20dB -81dBm 1s
    420 B3 1675 -117dBm -20dB -84dBm 1s
    436 B3 1675 -113dBm -20dB -83dBm 4s
    453 B7 3350 -125dBm -20dB -93dBm 1s
    502 B3 1675 -112dBm -19dB -81dBm 1s
    502 B7 3350 -116dBm -18dB -88dBm 1s

    Syntax:

    [admin@Chateau] interface/lte/at-chat lte1 input="at+qnwlock=\?" wait=yes
    output: +QNWLOCK: "common/4g",<num of cells>,[[<freq>,<pci>],...]
    OK

    Disable Cell Lock:

    interface/lte/at-chat lte1 input="at+qnwlock=\"common/4g\",0"

    Query:

    interface/lte/at-chat lte1 input="at+qnwlock=\"common/4g\""

    1x CellLock:

    interface/lte/at-chat lte1 input="at+qnwlock=\"common/4g\",1,1675,64"

    2x CellLock’s:

    interface/lte/at-chat lte1 input="at+qnwlock=\"common/4g\",2,1675,64,1675,70"

    3x CellLock’s:

    interface/lte/at-chat lte1 input="at+qnwlock=\"common/4g\",3,1675,64,1675,70,3350,64"

Hi! will this lock persist after system reboot on the Chateau ?

No, it needs to be re-applied after every reboot or interface reset.

Thanks, I figured it out after trying. Resolved this with a scheduler entry :)
