I recently purchased LHGGM&EG18-EA device and I do not know how to lock a cell on the device.
Procedure described in documentation https://wiki.mikrotik.com/wiki/Manual:I ... at_command does not work and I keep getting output: ERROR message in the terminal window.
Any idea which command can be executed to lock a cell on that device ?
Re: Using cell lock on LHG LTE18
I searched for this, too.
Looks like the LTE18 modem is Quecktel EG18 and it has no such ability.

Re: Using cell lock on LHG LTE18
There is a way to do a cell lock on EG18-EA modem, it worked for me on LHG LTE18 kit.
All information below is taken from this thread on the Quectel forum.
You will need to figure out PHY-CELLID (ID of the cell itself) and EARFCN (frequency that will be locked as primary band). You can get a list of cells around you and corresponding frequencies using cell monitor via web UI or console with:
You will get something like this:
Next, use the following command to set a cell lock:
where 247 is PHY-CELLID and 2850 is EARFCN.
Apparently you can set up to 20 cell locks and your modem will lock on the one with the best signal:
If you did something incorrectly or currently locked cell is not available anymore, use this to disable cell lock:
If you want to see currently set cell lock, use the following command:
Unfortunately, similar to R11e-LTE6 modem (LHG LTE6 kit), a cell lock will be reset after device reboot.
