1. A method for network registration, comprising:
obtaining, by a multi-SIM terminal upon registering a Subscriber Identification Module (SIM) card of the multi-SIM terminal to a network, an International Mobile Equipment Identity (IMEI) and multiple International Mobile Subscriber Identities (IMSIs) of multiple SIM cards in the multi-SIM terminal;
sending, by the multi-SIM terminal, the IMEI and the multiple IMSIs to a network device in the network, wherein the IMEI and the multiple IMSIs are configured for the network device to generate an authentication result based on stored mapping relations, each of the mapping relations being configured for indicating a correspondence between an IMEI and multiple IMSIs; and
receiving, by the multi-SIM terminal, the authentication result fed back from the network device, wherein the authentication result is used for indicating whether the SIM card is allowed to reside in the network.
