Operator (TURKCELL) connection problem (AT+COPS=0) with nRF9160-DK

[Bunyamin Ozcelik]

Hi,
I'm Bunyamin from Turkey. I've obtained an nRF9160-DK and inserted a TURKCELL M2M SIM card.
1- I installed modem firmware mfw_nrf9160_1.3.3
2- I flashed nrf9160dk_asset_tracker_v2_ltem_2022-06-02_880c82db.hex (or nrf9160dk_asset_tracker_v2_nbiot_2022-06-02_880c82db.hex , I get the same result)
3- I connected to nRF9160-DK with LTE Link Monitor
4- I sent the AT commands below:
->> AT+CFUN=0
->> AT+CEREG=5
->> AT+CSCON=3
->> AT%XEPCO=0
->> AT%XSYSTEMMODE=0,1,1,0
->> AT+CGDCONT= 0,"IP","nbiot"
->> AT%XSYSTEMMODE=0,1,1,0
->> AT+CFUN=1
->> AT+CFUN?
5- After these commands, I receive the log below:

6- Still AT+COPS=0. I cannot connect to the operator (TURKCELL).

7- It is interesting that, I receive +COPS: (1,"","","28601",9),(3,"","","28602",9) than +COPS: 0 again.

Can anyone help me?

Hi,

The log shows that the device finds two different cells that it tries to connect to, but it gets rejected with reject cause #15 and #14 respectively.

(I have cleaned up the log a bit to highlight the relevant lines)

Here is what the LTE spec says about the reject causes:

Cause #14 – EPS services not allowed in this PLMN
This EMM cause is sent to the UE which requests service, or if the network initiates a detach request, in a PLMN
which does not offer roaming for EPS services to that UE.

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.

Both reject causes point to a problem with your subscription and/or coverage.

Does your SIM card support NB-IoT or LTE-M (you only have NB-IoT enabled in the log)?

Is there NB-IoT coverage at your location?

Best regards,

Didrik

Hi Didrik,

Thanks for your reply.

I called TURKCELL support center and asked the settings of APN. Than, I made the APS settings as NBIOT. So, the problem solved. Now, I can connect the operator (TURKCELL). 

AT+COPS?

+COPS: 0,2,"28601",9

OK

Thanks for your advice.
