Abstract: A data transmission method and a terminal include multiple operating systems, and each operating system corresponds to a transmission module. The terminal determines a target transmission mode for data of the terminal when a data transmission command for transmitting the data of the terminal to a target terminal is received, and the target transmission mode includes a normal transmission mode and a secure transmission mode. The terminal switches to a designated operating system of the multiple operating systems when the target transmission mode is the secure transmission mode, establishes a connection with the target terminal via the designated operating system, determines whether the target terminal supports secure transmission, and transmits the data to the target terminal via the secure transmission mode when the determination result is that the target terminal supports the secure transmission.

Abstract: The present invention provides a data processing method, which is used for a terminal comprising a plurality of operating systems, and the method comprises: determining a first operating system currently used by the terminal when a command to store data in a Subscriber Identity Module (SIM) card in the terminal is received; storing the data in a first storage area of the SIM card when the first operating system currently in use is a designated operating system amongst the plurality of operating systems of the terminal, and storing the data in a second storage area of the SIM card when the first operating system currently in use is a non-designated operating system amongst the plurality of operating systems of the terminal. Correspondingly, the present invention also provides a data processing apparatus and a terminal.
