RouterOS Beginner Basics
1

Hello,
I need help with connecting to specific tower. I tried to use cell locking:

[admin@MikroTik] > /interface lte at-chat lte1 input=“AT*Cell=2,3,75,211”

but I get info:

output: +CME ERROR: Operation not supported

Model: LHGG LTE6 kit (model R11e-LTE6)

RouterOS version is 7.16
RouterBoard version is 7.16


I would appreciate any help…

OK, so I was wrong with modem model. The modem model is Fibocom R11eL-FG621-EA. So command should be:
/interface lte at-chat lte1 input=“AT+GTCELLLOCK=1,0,0,earfn,pci”
