For the mobile phone with the Micro-SIM card slot as the SIM card slot, by using the technical scheme provided by the present invention, the structure of the IC card reader/writer conversion device 110 can be made into a card sleeve structure matched with the Micro-SIM card slot, and the shape and size of the groove in the IC card reader/writer conversion device 110 of the card sleeve structure can be made into the shape and size capable of being embedded with the Nano-SIM card.
