A service response method and apparatus, a terminal, and a storage medium, relating to the technical field of communications. The method is applied to a terminal equipped with at least two SIM cards, and the at least two SIM cards comprise a first SIM card and a second SIM card. The method comprises: when the second SIM card has a service need, releasing a target hardware resource occupied by the first SIM card, and allocating the target hardware resource to the second SIM card, wherein after the target hardware resource is released, at least one network connection between the first SIM card and at least one network device is kept connected (202); and responding to a service of the second SIM card by means of the target hardware resource, and responding to a service of the first SIM card by means of the remaining hardware resources (204). According to the solution provided in the embodiments of the present application, the problem that a service of a first SIM card is interrupted when a service of a second SIM card is responded to can be avoided, and the effect of simultaneously responding to services of the two SIM cards by using limited hardware resources is achieved.
