Thank you Jan for your quick response. I tried the code you recommended in https://vodafoneiot.sodaq.com/quick-start/next-steps/ and entered the AT commands in the serial monitor but the command AT+COPS=1,2,“27201” hung so I tried AT+COPS=0 as you advised in:
NB-IOT in Germany with Vodafone SIM
I could proceed further until I got to command: AT+USOCR=17 Response:
+CME ERROR: No connection to phone
If you have any advice on how to troubleshoot this, or if you have any other useful tutorials for complete beginners I would be very grateful. It would be super to be able to get a message out and start the fun stuff.
