1. A method for data service transmission, the method comprising:

  • generating a first request when the mobile communication device is in a roaming state;

    the first request is used for the mobile communication equipment to acquire the card information of an identification card of a communication network corresponding to the current roaming place from a server which manages the identification cards of M communication networks corresponding to different roaming places;

    m is a positive integer;

    the identification card is a virtual user identification card of a roaming place;

    the mobile communication equipment establishes data connection with a communication network corresponding to a current roaming place based on the card information of the first preset card;

    the first preset card is a virtual subscriber identity card for international roaming;

    the mobile communication equipment sends the first request to the server based on the data connection to obtain the card information of the identification card;

    the mobile communication equipment unloads the card information of a first preset card in a communication subunit and loads the card information of the identification card to the communication subunit;

    the communication subunit reads the card information of the loaded identification card, and establishes data connection between the mobile communication equipment and a communication network corresponding to the current roaming place based on the card information of the identification card; and

    executing data service transmission under the communication network, wherein the card information of the identification card at least comprises identity identification information used for authenticating the identification card by the network and encryption information used for ensuring information encryption when the mobile communication equipment interacts with the network information.
