Abstract: A method and an electronic device for operator network switching are provided and relate to the field of terminal technologies. A currently activated profile in an electronic device is a first profile. Specifically, the method includes: accessing, by the electronic device, a first operator network based on the first profile; detecting a second operation after disconnecting a connection to the first operator network in response to a first operation; searching for a network based on stored profiles in response to the second operation, to obtain network search results corresponding to the stored profiles; activating a second profile based on the network search results corresponding to the stored profiles; and accessing a second operator network based on the second profile. In this way, operator network switching is implemented.

Abstract: A network search method for SA 5G service auto-provisioning is disclosed, including: user equipment sends a registration request to a network side device to request to register the user equipment with a 5G network, and a networking mode of the 5G network is standalone networking SA; the user equipment receives a registration reject response from the network side device when no available 5G subscription data of the user equipment is obtained through query, where the registration reject response is used to notify the user equipment that the registration with the 5G network fails; the user equipment receives a notification short message from the network side device after the network side device provisions a 5G service for the user equipment; and the user equipment sends the registration request to the network side device again in response to the notification short message.

Abstract: This application provides a method for returning from a low-standard network to a high-standard network, to resolve a problem that a primary card of a terminal device in dual SIM dual standby single pass mode cannot return to the high-standard network after falling back from the high-standard network to the low-standard network during a data service. The method includes: detecting that a first subscriber identification module SIM card of the terminal device falls back from a first-standard network to a second-standard network; obtaining a registration status of a second SIM card, where the registration status includes an operator of the second SIM card and a network on which the second SIM card camps, and the first SIM card and the second SIM card enable the terminal device to work in the dual SIM dual standby single pass mode; obtaining a target standard network based on the registration status of the second SIM card; and registering the first SIM card with the target standard network.
