摘要

The present disclosure relates to a SIM card sharing method and device, a communication device, and a storage medium. The SIM card sharing method applied to the first device may include: in response to the first device's requirement for obtaining cellular mobile communication, sending share request information to a second device through an interactive channel, where the interactive channel is established between the first device and the second device through a preset connection manner; receiving SIM card information that is returned by the second device based on the share request information; and establishing a cellular mobile communication connection with the base station according to the SIM card information.

說(shuō)明書

  • authentication information generated by the first device based on an authentication factor and a preset algorithm pre-negotiated with the second device.

    • In some examples, as shown in FIG. 2B, the step S133 may include:

      • S133A, transferring the authentication request to the second device based on the interactive channel;
      • S133B, receiving the authentication response returned by the second device based on the authentication request.

    For example, the SIM card information sent by the second device may be partial information of the SIM card of the second device. In this case, the authentication response still needs to be generated by the second device.

    Therefore, in the present example of the disclosure, after receiving the authentication request, the first device transfers the authentication request to the second device through the interactive channel. After receiving the authentication request, the second device calculates information required for the authentication response based on a part of the SIM card information of the second device that is not sent to the first device, and sends the generated authentication response to the first device through the interactive channel. In this way, the first device will obtain the authentication response generated by the second device by transferring the authentication request and receiving the authentication response.
