This product already has a band lock capability via the GUI. However there is also a cell lock capability via command line via gsmctl modem command. However this also requires a custom script such that cell lock is persistent across reboots, based on answers to other topics I have read here.
Please consider adding cell lock ability on the GUI to make this easier as this is a useful feature that many of us I guess will need at some point. I was thinking something like a scanner for neighboring cells and the ability to select the detected cells/bands just like we can now select just the bands. Essentially a graphical equivalent of the following commands:
gsmctl -A ‘AT+QENG=“NEIGHBOURCELL”’
gsmctl -A ‘AT+QNWLOCK=“4g/lte”,x,EARFCN,PCI’
Only reboot persistent.
Please share your thoughts.
