The invention discloses an electric power information transmission method and transmission apparatus. The method comprises: when sending electrical power information to a background by a first network, a mobile terminal detects whether a second network exists in a preset range of the mobile terminal to obtain a first detection result; under the circumstance that the first detection result indicates that the second network exits, the second network is registered; when registration of the second network is done successfully, whether the mobile terminal meets a condition of switching from the first network to the second network is detected and a second detection result is obtained; and when the second detection result indicates that the mobile terminal meets the switching condition, switching from the first network to the second network is carried out and the electrical power information is sent by the second network. Therefore, a technical problem of poor stability during the remote electrical power information transmission process can be solved.
