Abstract: A method and an apparatus for displaying a network name are provided. A first mobility management device in a first network acquires first network name information, where the first network name information is a network name currently displayed on a user equipment UE, and/or a public land mobile network identity PLMN ID corresponding to the network name that is currently displayed on the UE, and the first network is a network with which the UE currently registers or a network of two networks with which the UE currently jointly register. If the UE switches over to a second network during a process of executing a service, the first mobility management device sends the first network name information to a second mobility management device in the second network, so that the second mobility management device sends, to the UE for displaying, a network name corresponding to the first network name information.
