ESM Reject Cause #32

[Gova]

Dear team,

I am in Sri Lanka and I got a sim card from Dialog Networks.

The network provider told, they added the APN to my SIM. They also mentioned 140 kbps data limit and network works on B8 band.

They gave me the APN name "nbiot" to get connected to their network.

I programmed the board with AT_CLIENT and 1.3.6 mfw.

I used XSYSTEM mode with 0,1,0,2 expecting the device to work only in NB-IoT.

I used AT+COPS=1,2,"41302" to manually connect to the network, with their MCC-MNC code.

Then I used, AT+CGDCONT=0,"IP","nbiot" to add the APN name before I start the modem.

Below are my logs.

I am facing issue with ESM Error code #32, which translates to "Service option not supported". The description for it reads "This ESM cause is used by the network when the UE requests a service which is not supported by the PLMN."

What am I missing? or is it with the operator?

Can we do anything from the device end, before we turn on the modem, for a successful registration?

Does it have anything to do with the APN name? Because, i was able to read in other questions that, ESM error code #33 means SIM was not registered to access that APN. 

Please advise.

With tons of thanks in advance,

Gova

Hello Gova, 

Are you able to provide a modem trace? Did you try connecting using the PDN library? Will need more information in order to discuss with our cellular team. 

Thanks! 

Kind regards,

Hello Oyvind,

Thanks for your reply.

I used the PDN sample,and made the following changes to the proj.conf file, to match my requirements.

CONFIG_NRF_MODEM_LIB_TRACE=y

CONFIG_LTE_NETWORK_MODE_NBIOT=y

CONFIG_PDN_DEFAULTS_OVERRIDE=y

CONFIG_PDN_DEFAULT_APN="nbiot"

CONFIG_PDN_DEFAULT_FAM_IPV4=y

I got the following output in terminal.

Also, here is the modem trace file.

trace-2024-04-05T12-50-51.285Z.mtrace

Firstly, I dont know if i have configured the PDN sample properly for my requirement and used it.
Because, with cellular monitor, I was able to see that, ESM Cause #111 was received.

Also, inspite of having CONFIG_LTE_NETWORK_MODE_NBIOT = y, why was AT%XSYSMODE=1,1,1,3 was sent to the modem? 

I still made a pristine build, before proramming it.

Your help is much appreciated.

Thanks,

Gova.

Hi Gova, thanks for providing the logs. Are you sure you need the PDN information? Are you able to connect without adding this? 

From the logs I see that you get reject cause EMM 15 and ESM 111, which from 3GPP TS 24.301 Annex A (EMM) and B (ESM) translates to

Cause #15 – No suitable cells in tracking area
This EMM cause is sent to the UE if it requests service, or if the network initiates a detach request, in a tracking
area where the UE, by subscription, is not allowed to operate, but when it should find another allowed tracking
area or location area in the same PLMN or an equivalent PLMN.
NOTE 3: Cause #15 and cause #12 differ in the fact that cause #12 does not trigger the UE to search for another
allowed tracking area on the same PLMN.

Cause #111 – Protocol error, unspecified
This ESM cause is used to report a protocol error event only when no other ESM cause in the protocol error class
applies.

Did you contact the network provider with this information?

Cause #32 – Service option not supported
This ESM cause is used by the network when the UE requests a service which is not supported by the PLMN.

Kind regards,
Øyvind
