Hello Espen,

Have you installed the nRF Command Line Tools and JLink drivers? What version of the Thingy:91 do you have? What operating system are you using? 

Kind regards,
Øyvind

Hi Øyvind.

Thank you for your ansers, they brought me quite a bit ferther.

However, i am facing a new problem when trying to avtivate the simcard via nrf connect. 

After several attempts, using the IMEI and PIN on the Thingy 91 product, i get the following error.

(There was an error adding your device: No device found for this id. The device has not yet been provisioned. Troubleshoot nRF Code 40412)

Do you have any sollution on that error?

Best regards
