The embodiment of the invention discloses a radio frequency circuit control method, and belongs to the technical field of communication. The method is applied to a mobile terminal. The mobile terminal is provided with a plurality of clamping grooves for containing main and auxiliary user recognition cards. The method comprises the steps of controlling main and auxiliary user recognition cards to be registered to a network; if the main and auxiliary user recognition cards belong to the same network operator, and when the main and auxiliary recognition cards share the same radio frequency circuit, within a receiving period of the auxiliary user recognition card, controlling a receiving circuit of the shared radio frequency circuit to be closed; according to the main user recognition card, monitoring target system information sent by a base station to the auxiliary user recognition card; if the target system information is monitored, controlling the auxiliary user recognition card to return response information to the base station. The invention further discloses the mobile terminal and a computer readable storage medium, and power consumption of the multi-card multi-standby mobile terminal can be lowered.
