MKR NB 1500 connection problems

[teapote]

Hi everyone,

I'm trying to connect my MKR NB 1500 board to my Azure IOT hub, following this tutorial: https://create.arduino.cc/projecthub/Arduino_Genuino/securely-connecting-an-arduino-nb-1500-to-azure-iot-hub-af6470.

Everything works well until the moment I upload the code on my board.
I have the following messages :
"Attempting to connect to the cellular network
AT
OK
AT+CMEE=0
OK
AT+CFUN=0
OK
AT+CPIN?
ERROR
AT+CPIN?
ERROR
AT+CPIN?
..."

And repeating "AT+CPIN?ERROR" indefinitely...
I'm sure that my code PIN is ok... could it provide from another issue?

PS: I'm using my personal phone SIM, which is a french SFR.

Thank you in advance for your answers !!

Regards,

Hello Everyone,

Could anybody help me with this topic?
I've noticed that even if SIM is not inserted, I still have the "AT+CPIN?ERROR" issue.

Should I insert my SIM in a different manner?

Thank you!
