Provided is a network access method and the method includes the follows. Information of a user identification card pre-stored by the mobile terminal is obtained from a specified storage space, and all network types supported by the mobile terminal based on the pre-stored information of the user identification card are determined. Network identifiers (IDs) of public land mobile networks (PLMNs) of all the network types supported by the mobile terminal are determined and added to an equivalent home public land mobile network (EHPLMN) list. If it finds a target PLMN that matches a network ID in the EHPLMN list when the mobile terminal arrives at a place of visit from a designated location and begins to search for networks, a communications connection is established between the mobile terminal and the target PLMN.
