+CME ERROR: SIM PIN required

NB-IoT

Hi,

I’m getting the error: +CME ERROR: SIM PIN required
after the next commands from: http://support.sodaq.com/sodaq-one/sodaq-sara-r410m/
AT+URAT=8
AT+URAT?
AT+CMEE=2
AT+CGDCONT=1,“IP”,“cdp.iot.t-mobile.nl”

Any idea how to enter a pin?

AT+CIMI also fails, earlier this command responded with a number.

I would recommend putting the sim in a phone and entering the pin.
You will then be able to set the SIM so that it does not require the PIN to be entered.
Then it should work fine for the above.
