Abstract

The embodiment of the invention provides an SIM (Subscriber Identity Module) card control method and terminal equipment, relates to the technical field of communication, and aims to solve the problemthat the service continuity of an SIM card in the current terminal equipment is relatively poor. The method comprises the following steps: determining that terminal equipment transmits a first servicethrough a first SIM card of the terminal equipment; when the first service satisfies a preset condition, controlling a second SIM card of the terminal device to switch to a first state, wherein the first state is one of the following states: a CSFB mode, a CS domain priority mode and a deregistration state in the network. The method is applied to the scene that the terminal equipment transmits the service through the SIM card.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method for controlling a SIM card and a terminal device. Background technique [0002] With the rapid development of communication technology, terminal equipment is more and more widely used, and users have higher and higher performance requirements for terminal equipment. [0003] At present, terminal equipment usually uses a set of radio frequency devices to realize the dual card dual standby function of the terminal equipment, because a set of radio frequency devices can only provide radio frequency resources for one Subscriber Identity Module (SIM) card in the terminal equipment at a time , so at a certain moment the terminal equipment has only one SIM card that can be in service state. Taking SIM card 1 and SIM card 2 as an example, when SIM card 1 is in service state (that is, SIM card 1 is processing a certain service, hereinafter ref...
