Hi,

Please create a new thread instead of posting in a 8 month old thread.

According to the GMSA map, there is one provider in your area: https://www.gsma.com/iot/deployment-map/

If you use the at_client, you can issue at command "AT%XSYSTEMMODE=0,1,0,0" prior to enabling the modem with AT+CFUN=1 to enable NB1 mode. If you still do not get a connection, please check with your local provider to see if there is coverage in your area.

Kind regards,

Håkon

I am glad to hear that it is working now.

If you send me a direct message with your location, I can provide you with the contact info to the regional sales manager for your area.

Kind regards,

Hi Håkon,

Thank You,

It's working now with at_client sample project.

I wanted NB-IoT firmware for nRF9160-DK, currently public released version is for Cat-M.

Where can I get NB-IoT firmware? atleast alpha or beta verison.

Best Regards,

Vinod

Hi,

1. Is the modem updated? You can download the latest modem version from here: https://www.nordicsemi.com/Products/Low-power-cellular-IoT/nRF9160/Download#infotabs

2. Could you try flashing this .hex file and see if it works better afterwards?

"nrfjprog --program uicr_tcxo.hex --sectorerase -f nrf91"

devzone.nordicsemi.com/.../uicr_5F00_tcxo.hex

3. Could you post the output from LTE Link Monitor if the above suggestions still fails?

Kind regards,

Håkon
