SIM selection
*************
The sim choice (eSIM or nano-SIM) can be configured in Devicetree by adjusting
the ``sim`` property in the ``sim_select`` node.

The Icarus boards provide the user with 2 options regarding SIM usage for
LTE-M/NB-IoT communication. Either using the on-board eSIM or using an
external nano-SIM. The SIM can be selected using the SIM select pin given by
the sim-gpios property by setting it to 0 (eSIM) or to 1 (external nano-SIM).
