I want to enable internet on my Raspberry Pi, so I ordered Raspberry Pi 3G-4G/LTE Base Shield V2 and Quectel UC20-G Mini PCle 3G Module.
I followed the instructions from https://sixfab.com/ppp-installer-for-sixfab-shield/ and edited the /etc/chatscripts/chat-connect script to add the AT+CPIN command.
After I entered
sudo pon, I get
+CME ERROR: SIM not inserted^M.
The whole chat-connect script is:12345678910111213141516171819# /etc/chatscripts/chat-connectABORT "BUSY"ABORT "NO CARRIER"ABORT "NO DIALTONE"# ABORT "ERROR"ABORT "NO ANSWER"TIMEOUT 10"" ATZOK AT+CMEE=2OK AT+CPIN?OK AT+CPIN="4231"OK ATE0OK ATI;+CSUB;+CSQ;+COPS?;+CGREG?;&D2# OK "at+cgdcont=1,\042IP\042,\042*A1*.net\042OK AT+CGDCONT=1,"IP","\T",,0,0OK ATD*99#CONNECT
The SIM-card is, of course, inserted.
It would be great, if you could help me.

Could you please remove the pin from the sim and try?

thanks for the quick reply!
I’m not able to do that.
But it works now. After I removed the shield from the Raspberry Pi, restarted, put it on again, do
sudo pon, the connection is established!
But I got another problem. Everytime I restart the Raspberry, the interface is not comming up when the pin header and USB is connected. I need to remove everything again, restart it and then, sometimes, it works. If the shield is only connected via USB, everything works fine. Hence I think there is a problem with the pin header connection in combination with USB. Do I need to turn something off?

Is there anything that is keeping the GPIO busy behind? Could you please check it?7 February 2019 at 7:47 AM #36472
I just use SPI in addition to the Shield. Which GPIOs are crucial?11 February 2019 at 3:27 PM #36531
Here is the pinout diagram of the shield.
