SOS! extra pdp context

IoT Modules LTE Standard Module
1

there is a problem (quectel ec200t-eu), I am unable to connect to TCP/IP or any internet protocols until I disable PDP context with CID 10 in my case. so is there any solution to use only first for example. or what command AT+CGACT? exactly does and. manually typing AT+CGACT = 0,10 takes to much time (in my case) and is there a way to save that setting?

NOTE: I have 2 devices with the same operator and settings and this problem only occurs with the second one, so is there a chance that this may be the cause of the problem?

is there a way to debug extra context like find where it comes from?

Check what is in at+cgdcont? response.
Please do not use screenshots for text.

at+cgdcont?

+CGDCONT: 1,“IP”,“3g.ge”,“0.0.0.0”,0,0,0,0,0,0
+CGDCONT: 8,“IPV4V6”,“IMS”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0,1,1
+CGDCONT: 10,“IP”,“3g.ge”,“0.0.0.0”,0,0,0,0,0,0

OK

Do you have the same on another device?
What if you delete context 10 ?

Hint: The command to do that is

AT+CGDCONT=10

You may need to use your AT+CGACT=0,10 command first, or power-up the modem with SIM removed to remove that context.

Does the problem follow the modem, or does it follow the SIM?

how to delete it? if you mean AT+CGACT=0,10 for example, it helps but after restarting, I have the same problem. and on another device, I do not have that problem.

after long tries I got an this result:

[2023-07-03_15:04:34:653]+CGACT: 1,1
[2023-07-03_15:04:34:653]+CGACT: 8,1
[2023-07-03_15:04:34:653]+CGACT: 10,0

when it is disabled (+CGACT: 10,0 ) I do not have problems and after restarting it stays in that condition (I do not know how I did it)
I again take another quectel and got the same error:

[2023-07-03_15:04:34:653]+CGACT: 1,1
[2023-07-03_15:04:34:653]+CGACT: 2,1
[2023-07-03_15:04:34:653]+CGACT: 8,1

but now extra is (+CGACT: 2,1) and same error. and same problem (if i do not use command AT+CGACT=0,2 in this case I am unable to connect to internet)

I can say that problem is with the operator which I use, I have the internet on my phone if I insert it, but when I insert the sim in the module I need to deactivate context if there is an extra except 1, and 8 with command AT+CGACT

[2023-07-03_15:04:34:653]+CGACT: 1,1
[2023-07-03_15:04:34:653]+CGACT: 2,1
[2023-07-03_15:04:34:653]+CGACT: 8,1

like I need to deactivate 2 one with the command AT+CGACT=0,2 otherwise I cant use the internet.

As explained earlier in this thread:

10

AT+CGACT?

+CGACT: 1,1
+CGACT: 2,1
+CGACT: 8,1

OK
AT+CGACT=0,2

OK
AT+CGACT?

+CGACT: 1,1
+CGACT: 8,1

OK
AT+CGACT=2

+CME ERROR: Invalid Param

this is a result of the command AT+CGACT=0,2 deleting context and I can use the internet but after restarting I have the same problem.
NOTE: I used anther module and extra now is 2 thats why there is no id with 10.

without a sim, I get invalid parameter errors.

What does AT+CGDCONT? show after a restart? I’d like to know what APNs are in what contexts now.

This looks like a problem created by an active MBN (Modem Configuration Binary) file. But I can see no MBN-related commands in my EC200T&UC200T AT Commands Manual.

And the usual AT+QMBNCFG="List" command isn’t implemented on my own EC200T-EU.
