The method comprises: determining a dual-SIM frequency band combination of a dual-SIM card device as a DSDS mode; determining that at least one of two SIM cards supports a VoWiFi service and a preference setting of the SIM card is mobile network priority or auto mode; and if the network signal strength of the current environment satisfies a WiFi switching threshold in a switching strategy (i.e., a second switching strategy) corresponding to WiFi priority, controlling the SIM card to switch to the VoWiFi service. In this way, the SIM card uses a WiFi network to carry a call service, without occupying radio frequency resources, and the other SIM card can normally use radio frequency resources.
