nRF9160 DK problem registering to network

Hello,

I have recently started an evaluation on nRF9160 DK in the UK.
I tried to run the Serial LTE or AT Client examples but I was not lucky to register to a network.
Using the NB IoT mode (since the UK has no LTE) I could see a tower (Vodafone) on the LTE Link Monitor and I could get the MNCMCC of the country.
But the kit never registered and it kept searching (LTE box blinking red and yellow).
I have used 3 different SIM cards. iBasis which came with the kit , Hologram Global SIM, and a Vodaphone Pay as you go.
All the 3 SIMs are activated and have credit.
Is there any one knows if there a coverage problem in the UK !
Is this normal ?

Kindly advice.

Hi,

From provided board examples, please use at_client sample application on your board and run the following AT commands:

Turn off the modem AT+CFUN=0

Provide more information about the modem with these AT commands
AT+CGMR
AT+CEREG=5
AT+CMEE=1
AT+CNEC=24
AT%CESQ=1

Turn on the modem AT+CFUN=1

Run AT+CFUN?

If these sequence does not work for you, please open, save and upload the log. Log file can be opened by clicking on Open Log File in LTE Link Monitor application.

Best regards,
Dejan

Hello dejans

Thanks for your reply.
I have attached the log file.
I used the NB Mode and the Hologram SIM card.
I guess Error #13 means the network did not allow roaming ?

0 dejans over 2 years ago in reply to MuhammadTharwat

Hi,

Error cause number 13 is related to roaming not being allowed in a specific tracking area.
It seems that there is no support for NB IoT in iBasis and Hologram cards. It might be similar for Vodafone.

I suggest that you contact your network operator and check with them which cards, if any, can be used in your case.

Best regards,

Dejan

Hi, Vodafone provide NB-IoT coverage in the UK.

You will need an LPWA specific SIM to connect to the network (not an off-the-shelf PAYG SIM) and configure the correct APN name on the device.

Hi,

Are there any updates with regard to connectivity issue that you had experienced?

Have you tried any other SIM card?
