Hi,

Device in question:

 Teltonika RUT9M series 2025

Device: RUT901
Kernel: 5.15.184
Firmware: RUT9M_R_00.07.16.3
Build: bae5a37252d
Build date: 2025-07-24 11:28:06

As per described here Locking Devices to a Mobile Cell - Teltonika Networks Wiki

All the other commands seem to work except the actual lockin command:

gsmctl -A 'AT+QNWLOCK="common/lte",2,<EARFCN>,<PCI>'

Just gettin +CME ERROR: operation not supported

When using gsmctl -A 'AT+QNWLOCK=“common/lte”

+CME ERROR: operation not supported

But when using gsmctl -D -A ‘AT+QNWLOCK=“lte”’
GSMCTL modem[0]: Debug mode enabled
GSMCTL Modem id: 0
GSMCTL modem[0]: Calling LGSM EXEC to execute AT command
+QNWLOCK: “lte”,1,6400,120

Any tips?

Hello again,

Unfortunately, the modem in the RUT901 device does not support cell locking.

Please let me know if there is anything else I can assist you with.

Please then update the arcitle to include precise models on the page, as this is false then:

Prerequisites

gsmctl commands can be used on all RUTOS routers via any type of command line interface (CLI) supported by the router. So all you need is:

Hello,

gsmctl commands can indeed be used on all RutOS routers. However, when it comes specifically to cell-locking commands, I would like to kindly remind you that these are not official, are not recommended for use, and are not supported on all of our routers.

Thank you for your understanding.

Best regards,

Well this is a partial lie as you are not specifing that you can’t use all the commands. Regardless, if you offer them and not specify that all of them don’t work on specific models, is just bad (even if they are not officially supported). Please correct your wiki.

Hello,

Specifically on the cell-locking instructions page, it is stated that this feature will not work on all devices, and that the instructions are not official and not recommended for use. This also means that using gsmctl commands with cell-locking options may not work on some devices.

Best regards,

Well that is load of bull. Per your own instructions, where it says nothing about the actual modem in the device:

The described method works with Teltonika RUT/RUTX/TCR/TRB series devices, that contain Quectel modems;

So please, update your wiki and don’t be so tense.
