Unlike a regular phone, the SDR hardware doesn't have a SIM (Subscriber Identity Module) slot. It's only possible to use virtual SIM-card feature of mobile application at the moment. This limitation prevents one from being able to use regular SIM-cards, hence from being able to interact with commercial GSM networks using the SDR PHY.

The idea of this task is to implement a PC/SC based interface to interact with a physical SIM-card.
