Abstract: In a network handover method disclosed in this application, when an electronic device accesses a first mobile network by using the first SIM card, the electronic device obtains network information of the first mobile network in a process in which the electronic device moves along a first route. When the electronic device predicts, according to the obtained network information of the first mobile network, that an exception is going to occur in the first mobile network, the electronic device accesses the second mobile network by using the second SIM card. In this technical solution, an electronic device having a dual SIM card can be handed over from a first mobile network to a second mobile network in advance when it is predicted that an exception is going to occur in the first mobile network, thereby reducing the possibility of frame freezing or network disconnecting when a user accesses the Internet.
