The invention relates to the field of communication, and provides a network registration method in a roaming scene and terminal equipment. In the method, a terminal device fails to register in a high-format first network (e.g., 4G network) of a PLMN of a first roaming place operator (e.g., mobile), and if a registration rejection message for indicating that a second network (e.g., 3G network or 2G network) of which the network format is lower than that of the first network is searched on the PLMN of the first roaming place operator is received, the terminal device performs registration in the first network (e.g., 4G network) of which the network format is lower than that of the second network (e.g., 3G network or 2G network). In response to the registration rejection message, the terminal device searches for a high-format first network on PLMNs of other roaming place operators of the roaming place, so that when the high-format first network is searched on a PLMN of a second roaming place operator (e.g., telecom) of the other roaming place operators, the terminal device is able to access the second roaming place operator of the other roaming place operators. The terminal equipment sends the registration request to request to register to the high-standard first network, so that the terminal equipment has more opportunities to register to the high-standard first network preferentially, and the user experience is improved.
