A method and an apparatus for displaying a network name are provided. By using a combined attach procedure or a combined tracking area update procedure, a user equipment UE registers with a long term evolution network and a first circuit switched domain network, and acquires a public land mobile network identity PLMN ID of the long term evolution network and a PLMN ID of the circuit switched domain network. The UE displays a first network name corresponding to a predetermined PLMN ID before a to-be-displayed second network name sent by a first network device on the long term evolution network is received. The predetermined PLMN ID is one of the PLMN ID of the long term evolution network and the PLMN ID of the circuit switched domain network.
