I’ve been working on setting up my RPI 4 with the 3G-4G/LTE Base Shield and Quectel EC25 following the instructions found here https://sixfab.com/qmi-interface-with-3g-4g-lte-base-shield-v2/ .
I am using a Twilio SIM card. The card is activated and verified by using my phone.
Here is the script:
pi@raspberrypi:~ $ cd /home/pi/files/quectel-CM
pi@raspberrypi:~/files/quectel-CM $ sudo ./quectel-CM -s wireless.twilio.com

The SIM_ABSENT has me worried? I tried the SIM out of my phone and received the same message.
I’m fairly new to IoT projects, so make sure to dumb your answers down a hair for me!
Thank You
