Hi,

I I am stuck in my project, I have to activate the physical sim card.

the documentation says you need "Set pin Sim_select0 to low to select the plastic SIM" but I don't know how to do it.

Sim_Select0 is Pin#19, Sim_Select1 is Pin#9 of the STMOD+ connector, configure and set the pins appropriately on the host board. PB12 and PD3 respectively
