The invention relates to a terminal, a subscriber identity module card releasing method and a computer readable memory medium. A first card slot (1), a Bluetooth card write module (2) and a master control board (3) are arranged on the terminal. The first card slot (1) is used for mounting a to-be-released SIM card. The master control board (3) is used for establishing Bluetooth communication connection with the Bluetooth card write module (2) through a Bluetooth communication module built in the terminal. The Bluetooth card write module (2) is also connected with the first card slot (1). The master control board (3) and the first card slot (1) are directly connected. Through application of the technical scheme, a release process of the to-be-released SIM card can be realized in the same terminal, the release process of the to-be-released SIM card is simplified, and the release efficiency is improved. Moreover, the occupation to the internal space of the terminal can be reduced, the change strength of the hardware is reduced, the adaptability of the Bluetooth card write module is expanded, and the use experience of a user is further improved.
