A method for operating a host device includes inserting a plug-in adapter, having a subscriber identity module (SIM) component disposed thereon, into a host receptacle of the host device. A memory card is inserted into a memory receptacle on the plug-in adapter. After inserting the plug-in adapter and the memory card, communications are conveyed between the host device and the SIM component via the adapter and the memory card.
