FG621-EA No PLMN locking?

Hardware MikroTik hardware general
1

Hey everyone,

I have an L23UGSR-5HaxD2HaxD-NM with an R11eL-FG621-EA.

When I set an operator using the MCC+MNC in roaming it just ignores it as it seems.
Other devices with the same SIM card can just switch between the different roaming operators using the MCC+MNC.
My google research didn’t give me any clues. Does the FG621 not support locking to a specified PLMN?
I also had no success in finding a AT command to lock the card to a specific PLMN.

Does someone here have any informations about this?
This is a very important feature for me.

EDIT: I’m on ROS 7.18.2 (stable) and Modem Firmware is the latest: 16121.1034.00.01.01.09

Thanks in advance!
Regards
Arne

If you search for FG621 in https://help.mikrotik.com/docs/spaces/ROS/pages/30146563/LTE it appears the GTCELLLOCK command doesn’t lock to PLMN (only channel/cell).

I dont want to lock to a specific cell. Just to a specific provider. Is that command internally used for the “operator” option in RouterOS?
So no provider lock for this modem? Thats kinda sad…

I don’t know what command RouterOS tries to use, but you should be able to see it in the log if you add this to your configuration:
