All mobile carrier cells are assigned a unique ID, which is broadcasted to all connected devices. It is usually irrelevant information for the end user, as cell switching on mobile phones and routers has become very good. But sometimes in '''remote areas''', it is beneficial to lock the LTE router to a single cell, as automatic mode may choose a cell with fewer or slower bands, as it only really looks for the '''best signal'''. '''For now, only devices with Quectel modems support this feature'''.

==Finding the modem manufacturer==

==Compatible modems==

In your device WebUI, go to '''Status → System''' page. Under the '''Modem''' section, you'll see the '''Model''' row.

Not all modems support cell locking. To find out if your device is compatible, in your device WebUI, go to '''Status → System''' page. Under the '''Modem''' section, you'll see the '''Model''' row:<br>

If the model starts with '''EG, RG, EC''', and '''not SLM''', this feature should work. However to make sure it's supported, command '''''gsmctl -A 'AT+QNWLOCK=?'''''' should '''not''' return '''ERROR''', when ran via [[Command_Line_Interfaces_RutOS#SSH|SSH]] or [[Command_Line_Interfaces_RutOS#CLI_.28WebUI.29|CLI]]. The response should look something like this:<br>
