E8T not use by SIM7600 4G module. E8T use by "EC200U-EU" version 4G module.
you need to write your own arduino code to ESP32 board firstly.
there are some E8T 4G module document , you can check at here: https://www.kincony.com/forum/forumdisplay.php?fid=36

I actually just posted my thread here randomly because I didn't know how to create one my apologies, I am not using the E8T module, I am just having an error when it comes to my sim on the SIM7600 module. Is your sim in the video 4G?

you should add exend power supply, there is pins for power and GND. USB port current is low.
