I have set up the Development Kit according to the following instructions and successfully activated the SIM card.
Unfortunately the LED4 still does not blink after three minutes. Therefore I cannot complete the setup process as described in the video.
My location is in Berlin, Germany.
I am grateful for any advice!
Remember that the nRF91 kit comes with the LTE-M version of the Modem firmware, and that Germany generally only have nb-iot coverage as far as I know.
Could you send me an personal message on Devzone then I can direct you to the Regional Sales Manager so you may receive a pre-release version of the nb-iot firmware.
