A network access method includes: determining with a mobile communications terminal if a network identity of a visited public land mobile network (VPLMN) exists in an equivalent public land mobile network (EPLMN) list, obtaining a shared network information stored in an operator's server and searching for the network identity of the VPLMN from the shared network information upon a condition that the network identity of the VPLMN does not exist in the EPLMN list, adding the network identity of the VPLMN to the EPLMN list, and accessing a network based on the EPLMN list.
