An operator network switching method, wherein the method is performed by an electronic device, the electronic device stores a plurality of profiles including a first profile, the first profile is a currently activated profile, and the method comprises: accessing, by the electronic device, a first operator network based on the first profile; detecting, by the electronic device, a first operation, wherein the first operation is used to disconnect a network connection; disconnecting, by the electronic device, a connection to the first operator network in response to the first operation; detecting, by the electronic device, a second operation, wherein the second operation is used to restore a network connection; searching, by the electronic device, for a network based on at least two profiles in the plurality of stored profiles in response to the second operation, to obtain a network search result corresponding to the at least two profiles; selecting a second profile from the at least two profiles based on the network search results corresponding to the at least two profiles; and when the second profile is different from the first profile, activating, by the electronic device, the second profile, and accessing a second operator network based on the second profile; wherein the method further comprises: sending, by the electronic device, a request to subscribe to a call transfer service to the first operator network, wherein the request to subscribe to the call transfer service is used to transfer an incoming call for a first telephone number to a second telephone number, the first telephone number is a telephone number comprised in the first profile, and the second telephone number is a telephone number comprised in the second profile; and notifying, by the electronic device, a user that an incoming call for the first telephone number is to be transferred to the second telephone number when receiving a first response for subscribing to the call transfer service, wherein the first response is used to indicate that the call transfer service is successfully subscribed to, and the first response is returned for the request to subscribe to the call transfer service. accessing, by the electronic device, a first operator network based on the first profile;
