1. A method comprising:

  • receiving, by a terminal device, an enabling request, wherein the enabling request is used for requesting simultaneous standby of a first subscriber identity module (SIM) card and a second SIM card in the terminal device, wherein the first SIM card is a software-implemented SiM card, and wherein the second SIM card is a hardware implemented SIM card;

    implementing, by the terminal device, a first SIM card network access process by interacting with a SIM card control module in the terminal device to complete a first network access process of the first SIM card using a data file of the first SIM card; and

    implementing, by the terminal device, a standby process by maintaining the first SIM card and the second SIM card in the standby state at a same time according to the enabling request, wherein the second subscriber identity module card has already accessed a network; and

    invoking, by the terminal device, a third-party invocation interface provided by an operating system of the terminal device, wherein the first SIM card interacts with the SIM card control module through the third-party invocation interface using a SIM mobile equipment (SIM-ME) function of the third-party invocation interface.
