Hi, I'll need more information to figure out your issue.

First, please download nRF Connect for Desktop and open the application LTE Link Monitor to view the output from the DK. Then press this button in the red square to get an actual output file and attach it in your next comment. This will make it much easier for me to see what's going on. 

Also, please answer a few questions.

1. Which provider are you using? (which company did you get the SIM card from)

2. Are you using NB-IoT or LTE-M?

Best regards,

Heidi

Device is in filed testing we can not flash the program. 

Could you please help us when will get rejection reason 8.(refer sanp attached in the post)

Hi, I'm sorry but I can't help you without more information. I don't know what you mean by "Device is in filed testing", but you don't need to flash a program. I want you to download a program on to your computer and use this to retrieve the complete output log from the device.

Where in the image is there an error 8? Which function is returning error code 8?
