Assign_plmn_in_limit_search

Hello, I wish to use the command AT+QCFG=“assign_plmn_in_limit_search” Specify Operator for Camping on a Cell with Limited Service.

I have the EG25 and the RM520NGL modules. Is this command supported on these modules?

I don’t see the command available when I run AT+QCFG=? on either module. Perhaps there is an alternative command available?

RM520NGL software version - RM520NGLAAR03A04M4G_01.202.01.202
EG25 software version - EG25GGBR07A08M2G_30.204.30.204

Dear @explorer
I didn’t found this At command in RM520N and EG25-G.

Why do you want to use it? lock operator or cell?
AT+COPS can configure specify operator.

Hi Silvia I just want to lock to operator but AT+COPS doesn’t seem to achieve this when in LIMSRV:

AT+QCOPS=2,1,1,1
+QCOPS: “3G”,“3 UK”,“23420”,“WCDMA 2100”,10564,97,DA548C,411,-92,-5
+QCOPS: “3G”,“O2 - UK”,“23410”,“WCDMA 900”,3025,55C0,3B86A06,81,-121,-31
+QCOPS: “3G”,“3 UK”,“23420”,“WCDMA 2100”,10564,97,DA5703,453,-87,-3
OK

AT+QENG=“servingcell”
+QENG: “servingcell”,“LIMSRV”,“WCDMA”,234,10,55C0,3B86A06,3025,81,155,-74,-12,-,-,-,-,-
OK

So lets say I want to lock to operator 23420:

AT+COPS=1,2,“23420”,2
OK

AT+QENG=“servingcell”

+QENG: “servingcell”,“LIMSRV”,“WCDMA”,234,10,55C0,3B86A06,3025,81,155,-79,-13,-,-,-,-,-

You can see it does not lock to operator 23420 but stays on 23410. Are my commands correct?

Dear @explorer
Please try AT+COPS=1,2,“23420”

Hello @silvia unfortunately this does not appear to work:

AT+QENG=“servingcell”
+QENG: “servingcell”,“LIMSRV”,“WCDMA”,234,10,55C0,3B86A06,3025,81,155,-80,-10,-,-,-,-,-

AT+COPS=1,2,“23420”
OK

AT+QENG=“servingcell”
+QENG: “servingcell”,“LIMSRV”,“WCDMA”,234,10,55C0,3B86A06,3025,81,155,-83,-12,-,-,-,-,-

AT+CFUN=1,1

AT+QENG=“servingcell”
+QENG: “servingcell”,“LIMSRV”,“WCDMA”,234,10,55C0,3B86A06,3025,81,155,-83,-12,-,-,-,-,-

Maybe I need to do something else?

Dear @explorer
I saw 23410 is O2, did you confirm your SIM card can register on O2 operator?

Dear @silvia thank you for the solution. The solution is to use a SIM card. It is not possible to select PLMN in limit search without a SIM card.
