if you have picocom installed you can check the output of the following AT command "AT+CGDCONT?" (should look like this):
AT+CGDCONT?
+CGDCONT: 1,"IPV4V6","internet",...
+CGDCONT: 2,"IPV4V6","ims",...
+CGDCONT: 3,"IPV4V6","sos",...
and i can advise you to remove the pin from the SIM and try again (if possible) just insert it into a mobile phone and remove the pin request ...
