A communication control method and apparatus, a terminal, and a network platform, where after generating a virtual subscriber identity module (SIM) card application request, the terminal sends the virtual SIM card application request to the network platform, then receives target virtual SIM card data returned by the network platform, and configures a target virtual SIM card in a baseband chip such that a user can conveniently change a SIM card only by downloading virtual SIM card data from the network platform using a network, regardless of a location of the user and time. In addition, according to the method, the user can conveniently select, with reference to displayed information about baseband chips, a baseband chip in which the target virtual SIM card data is configured, and does not need to repeatedly detach and mount a SIM card slot of the terminal for confirmation.
