Initial setup of 3g/4g base hat with Twilio

yes, buster, RPi3B+ or 4?
the hat is being recognized on boot then being removed.
would you be comfortable uploading your config.txt file & a fresh dmesg boot log?
config.txt location == /boot/config.txt
for dmesg >

  1. sudo dmesg -C, then reboot.
  2. at terminal session: sudo su
  3. dmesg -T > /var/log/dmesglog.txt (or whatever path & file name you like)
  4. exit (gets you out of root)
