A schematic example could be:
5.7.4. SIMIN Detection
All the GPIO pins can be used as SIM DETECT input. The AT Command used to enable
the function is:
AT#SIMINCFG
Use the AT command AT#SIMDET=2 to enable the SIMIN detection
Use the AT command AT&W0 and AT&P0 to store the SIMIN detection in the common
profile.
NOTE:
Don’t use the SIM IN function on the same pin where the GPIO
function is enabled and viceversa.
