nRF9151 DK + SIM card registration rejected

[Jachym]

Hello all,

I've just bought nRF9151 DK and went with Quick Start. I loaded nRF Cloud multi-service sample. 
Sample runs and connect to network. Sometimes it sends data (location + temperature) but only once.
After that I got disconnect from network and end up in attaching state forever.

The behavior of the sim cards is totally the same (Onomondo and wireless logic).

I saw that in Czech Republic eDRX and PSM is not support for LTE-M either NB-IOT.
Should I somehow disable these features? 

I am including log file.

Thank you for help.

Hello, 

Yes, your device is being rejected by the network, on both NB-IoT and LTE-M. There are several EMM reject causes provided (in ascending order). 

Cause #9 – UE identity cannot be derived by the network.

      This EMM cause is sent to the UE when the network cannot derive the UE’s identity from the GUTI/S-TMSI/P-TMSI and RAI e.g. no matching identity/context in the network or failure to validate the UE’s identity due to integrity check failure of the received message.

Cause #13 – Roaming not allowed in this tracking area

      This EMM cause is sent to an UE which requests service, or if the network initiates a detach request, in a tracking area of a PLMN which by subscription offers roaming to that UE but not in that tracking area.

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 #19 – ESM failure

      This EMM cause is sent to the UE when there is a failure in the ESM message contained in the EMM message.

Could you please provide a modem trace from your device when you see these issues?

One thing to test is using a local SIM from e.g. Eurotel or Vodafone CZ. See GSMA Mobile Deployment map for LTE-M and NB-IoT coverage in Czech Republic. Looking at the coverage map of the Onomondo SIM it seems that they do not have roaming coverage in Czech Republic, but Wireless Logic seemingly has.

Kind regards,
Øyvind

Hello Øyvind,

Thank you for quick response.

I see this issue every time, it is not sporadic. Unfortunately right know I don't have another SIM so I have to order one from Vodafone. 

I include modem traces as you request (used SIM Wireless Logic).

Google disc - traces 

BR, 
Jachym

[Øyvind]

Hello, and thanks for providing the modem trace!

Looking through the modem trace it can seem that there is an issue with the IP. The device reports ESM: 50 

Cause #50 – PDN type IPv4 only allowed

      This ESM cause is used by the network to indicate that only PDN type IPv4 is allowed for the requested PDN connectivity.

In prj.conf, please ensure:

CONFIG_NET_IPV4=y

CONFIG_NET_IPV6=n

Let me know how that works for you

Kind regards,
Øyvind

[Jachym]

Hello, 
Unfortunately, activating only IPv4 is even worse. DK will not connect to the network at all.
I am attaching traces (the new ones are with the IPv4_ prefix): Google disc - traces

BR,
Jachym

[Øyvind]

Thanks for testing. 

I will need to investigate and discuss this internally to why your device is still rejected by network.

Kind regards,
Øyvind

[Øyvind]

Can you please capture a modem trace using each SIM card? Just to verify that both SIM seeing the same issue.

Thanks!

[Jachym]

I captured traces with onomondo sim card. The behavior looks the same as conexa.
I am attaching traces (the new ones are with the onomondo_prefix and conexa without any prefix): Google disc - traces

BR, 
Jachym
