Thingy91 LTE connection to nRF Cloud

[GlenT]

I updated the firmware according to the video "https://www.youtube.com/watch?v=xQ7hDzRULJQ&t=314s&ab_channel=NordicSemiconductor"

File for "update modem" : mfw_nrf9160_1.3.0.zip
File for "Add HEX file" : img_fota_dfu_hex --> thingy91_asset_tracker_ltem_2021-06-28_7a076c22.hex.

All the files were found on Nordic and are the latest release.

I created an account on the nRF cloud and activated the iBasis eSim to my account. 

When looking in the nRF connect toolchain app I have 2 bars on the signal indication but the LTE won't connect and are switching between yellow and red in the nRF Connect software, while the thingy91 is only pulsating/blinking blue light. It has been searching for 4 hours now and nothing seems to be happening. According to other similar posts, the issue often seems to be the sim card. 

Any suggestions?

regards Glen

*Edit*
The eSim was added with the SIM ICCID and puk code. I have also verified that the numbers are correct on my profile on nRF Cloud. I am living in Norway

Dear GlenT,

I learned myself some weeks ago - that the I-Basis SIM Cards wre delivered with an limited validity. Caused me some headaches, but was relatively quick solved by I-Basis by an mail to  Support iBasis <[email protected]> .  Describe your problem stating the Thingy Sr. No. and date of manufacture and the data of your SIM card. 2 weeks later I received a new card from I-Basis - it worked immediately. In the meantime, I-Basis has recognized the problem with this limited validity and has certainly found a solution -> it should go faster. Whenever there is really a SIM card problem. Stay healthy

Thank you for the reply cegre :) 

I have now sent a mail to the Support iBasis as suggested and I'm hopeful this will do the trick! 
I am able to get readings from the LTE Link Monitor in the toolchain application. Do you know if there is some type of commands I can post that will give me some feedback that the thingy91 is running correctly? I would like to see some kind of verification or status indicating that the thingy har the correct setup 

best regards Glen

Sorry, I'm still a beginner  in this NRF9160-Topic -  but maybe you can check the screenshots  within my ticket " Thingy91 - start-up problem will not connect to LTE - please help :-)"  two months ago - if you see a similar behaviour.  According to my first experience  your updated files should be the right ones. 

There exists an AT-Command Doc  https://infocenter.nordicsemi.com/pdf/nrf91_at_commands_v1.0.pdf

or Youtube Video: https://www.youtube.com/watch?v=1jgImp7FBy8   starting with 27:03  will give you an impression how these commands works.    An easy command is   AT+CIMI  (  SIM Card No.) .

Hope this will help and greetings from Germany and maybe in the next autumn/winter season I will have time to improve my Thingy/Nrf9160 knowledge.
