CEREG: Reject - #14 "EPS services not allowed in this PLMN"

[optical]

Hello,

we are experiencing rejection from the network by receiving cereg notification. Modem afterwards stops attempting to connect to network. Which results in application getting stuck due to this unhanded case.

How should we proceed when this case is encountered ? Does the modem needs some additional at commands to recover ?
Can we somehow set the modem to keep trying after this event ?

Hello Tomas,

However, i'm unable to get OK response for any of the mentioned AT+CFUN=x commands.

I checked with the modem team, and it turns out that while modem is active (+CFUN=1), it is not possible to switch on/off the SIM card. But it should work when the modem is turned off (+CFUN=0), see log below:

Is it possible to assemble a list of rejection codes, which places the PLMN to the "list of forbidden PLMNs for GPRS service" ?
Is there option to readout current list ?

The reject cause codes are not defined by us, they are part of the 3GPP standard, which the nRF9160 modem follows. Referring to technical specification # 24.301, Annex A. 

Cheers,

We have contacted our carier with this concrete issue with logs and time of the CEREG: Reject - #14 "EPS services not allowed in this PLMN".

Their response:

Dear team,

We have investigated the provided IMSI and we observed that, any create session didn't reached our P-GW, as you can see in the logs below:

/CDR_DIA.sh 20220824 901288003656775 100224500

Script V2.1

Time Stamp [UTC] IMSI Device IP APN CDR SGSN IP GGSN IP Byte In Byte out GDSP Node IMEI Radio Type

We have checked the HSS db and it's properly attached under Vodafone CZ, as you can see below:

EpsLocState: 1 (Which Means Attached)
EpsMmeAddr: mmec50.mmegiff37.mme.epc.mnc003.mcc230.3gppnetwork.org
EpsMmeRealm: epc.mnc003.mcc230.3gppnetwork.org
EpsLastInsertSent: 20220811T174030898
EpsMmeOdb: 0
EpsMobilityNotifInfo: 38
EpsMmeRegServ: FALSE

Also we have tried to extract a control plane trace and we didn't find any sessions there either, please find attached a screenshot.

Please let us know if there are any devices affected, provide us examples along with a fresh timestamp, not older than 48h in order to involve the Local Opco.

If is the only device affected, please try to perform a test by inserting the SIM into a working device this would helps us to exclude an issue with him and if the issue still persists, please give us a fresh sample.


This leads us to believe there might be incorrect reaction by the modem firmware in some situation. Could you please help us how to proceed ? 

[Didrik Rokhaug]

Hi,

Markus is out of office, so I have taken over the case.

Could you take a modem trace, so we can get more insight into what the modem is doing?

Best regards,

Didrik
