The SIM activation will never finish

[Ken Takahashi]

I followed the “Getting started with nRF9160 DK” page (docs.nordicsemi.com/.../nrf9160_gs.html) to activate my iBASIS, However, the process is still not finished with “Activate SIM Card”.

Select Quick Start in “nRF Connect for Desktop”.
Select “Asset Tracking” in “Select an application to program”.
Install Modem core Firmware v1.3.6, Application core Asset Tracker v2.
The message “Verification successful” is displayed.
Then, connect to nRF Cloud and start SIM activation.

For reference, if you enter “AT+CSQ” using AT commands, you will get +CSQ:99,99 back. Can't it be used with Japanese LTE?

Hi Ken,

I have reported this to the Cloud team and will get back to you as soon as I get a response.

The iBasis works in Japan on LTE-M. See https://ibasis.com/solutions/iot-connectivity/network-coverage/

Does the nRF Cloud SIM activation indicate that the activation was successful?

Do you have the correct SIM in the device, the activated one?

Please note that the "AT+CSQ" is G2 and G3 networks. For example in my test device, the cloud connection is working, the "AT+CSQ" gives the "99,99" indicating that there is no signal. 

If you keep the serial terminal open to see traces from the Asset Tracker v2 app, what does those traces say?

Are you connecting to nRF Cloud or your own service? If you are trying to connect to the nRF CLoud, did you "add Device" to your account?

Hi Tuomas, 

Thanks for your advice.

I just retry to continue the Exercise 1 on academy.nordicsemi.com/.../

But, i still cannot do "6. Activate the SIM card."

Then , it display below messages on Serial Terminal console:

[00:11:51.928,466] <wrn> location: Current cell ID not valid
[00:11:51.928,466] <wrn> location: No cellular neighbor cells or Wi-Fi access points found
[00:11:51.928,527] <err> location: Location acquisition failed and fallbacks are also done
[00:11:51.928,558] <wrn> location_module: Getting location failed

I am following the instructions in Exercise 1.
However, it seems that the actual display differs from the web instructions:

https://academy.nordicsemi.com/courses/cellular-iot-fundamentals/lessons/lesson-1-cellular-fundamentals/topic/lesson-1-exercise-1/.

Actual Display:

I just trid to add LTE Device.

The display was indicated "There was an error adding your device: No device found for this id. The device has not yet been just-in-time provisioned. Troubleshoot nRF Code 40412"
The Code 40412 is 
" No device found for this id. The device has not yet been provisioned."

I followed the resolution column to find out.
I determined that all ID, PIN number and other codes are fine.
I suspect that the LTE connection is not working.
In fact, I entered the AT+CESQ command and got the following response.
> AT+CESQ

+CESQ: 99,99,255,255,255,255
What is the problem with a strong signal but no connection?

[Ken Takahashi]

I was able to activate the SIM and register it on the device.
After investigating the cause, I found that the band lock status of the nRF9610DK's default settings was different from the LTE bands in Japan, so I was able to register it without any problems after making the correct settings.
Thank you for your cooperation.
