for g in 509 404 402 504; do echo $g > /sys/class/gpio/export 2>/dev/null; done

# match stock Android EXACTLY — direction first, then value
echo out > /sys/class/gpio/gpio509/direction; echo 1 > /sys/class/gpio/gpio509 ...

Get the reference from stock EDL Android.
Boot stock, insert a physical SIM, confirm it registers, then "cat /sys/kernel/debug/gpio".
That dump is the exact known-good state of esim1/2/3_en + sim_hotplug.
Replicate those states under Handsomes Mobian, then compare.

Under Mobian:
install gpiod ...

how did it worked?
do you still need any help?
