Lock EC25 modem on a specific PLMNID

Dear Mortezaaliahmadi,
Thanks for your inquiry in Quectel forums. Please check the following test AT log in my side. Thanks!

Thanks Kyson, what do you think about my results?

AT+COPS?

+COPS: 1,2,"43235",2

OK
AT+COPS=1,2,"43211",2

OK
AT+COPS?

+COPS: 1

OK
AT+QNWINFO

+QNWINFO: No Service

OK
AT+QENG="servingcell"

+QENG: "servingcell","LIMSRV","WCDMA",432,35,5962,9C563EF,2993,448,1,-71,-10,-,-,-,-,-

OK

The last output indicates that the serveing cell MNC is the old value (35) and not the new (11). It seems that the lock process is not done!

Dear Mortezaaliahmadi,
Please note that you have lock PLMN to 43211, but it return 43235 when you use AT+QENG=“SERVINGCELL”, they are different PLMN,so the module can not attach the network, and “LIMSRV” means that it limited to access. Do you still think there have any issue ?

My aim is to have some informations about the serving cell or neighbouring cells in a different MNC. I saw in the mobile phone diag that sometimes the SIB informations of the cell in the other MNC are recieved. So I want to recieve them manually. But my outputs in the previous comment indicate that no camping on a cell of the other MNC is occured and consequnetly no SIB informations are recieved.

Dear Mortezaaliahmadi,
If that, you can try the following method to get your needed information. Thanks!
1.Do not plug the SIM card.
AT+QMBNCFG=“DEACTIVATE”
2.Reset the module
3.Use the following command to check the nerighbouring cell or other MNC.

Thanks, I test it and my results are as follows with an ERROR:

OK
AT+QENG=“neighbourcell”

Dear Mortezaaliahmadi,
For your question, it is better to upgrade the module FW to have a try again. The FW you used is too old. Thanks!
Please check the Following link, you need to install the USB driver in your Windows PC firstly, then unzip Qflash package, connect to USB DM port, unzip EC25 firmware package, choose any file in firmware package, then click start button, it will upgrade the firmware automatically, you just need to waiting for the upgrade successful. Thanks!

The following is my test results, please check. Thanks!

Dear Kyson,

[2019-12-11_11:49:27]at+qcops=?
[2019-12-11_11:49:27]+QCOPS: (0-7),(0,1),(0,1),(1-5)

0-7 is the techology selection and the 2nd parameters was for showing more info.
What do the last two parameters of the AT+QCOPS command mean?

Dear Gerko,
Please check the following explanation about the AT+QCOPS command. Thanks!

Thank you very much for the clear description!

Dear Kyson,

What is the use of AT+QMBNCFG=“DEACTIVATE” command?

Thanks

Dear Ketan,
The command means that deactivate the activated MBN setting. As you know that MBN file is the related setting information about the operator, when you insert SIM card, the module will active the corresponding MBN file. So when you do not plug SIM card to check the cell information, it is better to deactivate MBN. Thanks!

Dear Kyson,
Why AT+QCOPS=2,1,1,5 neighbour cells in the result are less than AT+QENG=“neighbourcell”?

at+qcops=2,1,1,5

Dear Mortezaaliahmadi,
Please double check the test results. Actually the AT+QCOPS=2,1,1,5** neighbor cells in the result are more than AT+QENG=“neighbourcell”.If you want to get more neighbor cells, it is better to use AT+QCOPS command. Thanks!
AT+QENG designed to report the information of neighbor cells, while AT+QCOPS is used to scan for current available networks, so it is normal that AT+QCOPS search more neighbor cells than AT+QENG. Thanks!

Thanks Kyson, but AT+QCOPS=2,1,1,5 returns 4 cells while AT+QENG=“neighbourcell” returns 8 (4 cells more than AT+QCOPS)

Dear Mortezaaliahmadi,
Please check the following picture about the explanation of the two commands, the return value are different. Thanks!
AT+QENG

AT+QCOPS

Yes, I checked them before and I know that the fields which are returned in these 2 commands are different. I mean that the records number in AT+QCOPS=2,1,1,5 is 4. It means that 4 cells is returned and PSC are 175, 453, 461 and (-). while AT+QENG=“neighbourcell” returns 8 records (8 cells) and PSC are 494, 83, 112, 8, 16, 40, 60 and 52)

Oh, yes, you are right. Just as i have said that AT+QENG designed to report the information of neighbor cells, while AT+QCOPS is used to scan for current available networks, so the results is normal. Thanks!

Thank you very much Kyson :slight_smile:

Hello Kyson, At this time have any module quectel support this command?
AT + QMBNCCFG = "DEACTIVATE
