How to add nrf cloud LTE modem

Hi All! 

I am using a hologram NB-IoT sim card in nrf9160DK. And want to connect it /send data to nrf cloud. I have activated the sim from the hologram website. When I tried to add the nrf9160Dk in nrf cloud as an LTE device it gives me a 40412 error.LED # 3 is continuously blinking. I read all the related issues but still fail to add the LTE device. The only issue I assume is about the NB-IOT hologram sim. Is it supported by the nrf9160DK modem?. The country I am using this hardware is Pakistan.

Thanks & Regards,

Muhammad Usman
