When there is a lot of data to be downloaded from the external server while the selected game application is loaded in FIG. 8C, an item for receiving a user's selection to temporarily release the limit of automatic communication network switching may be added. For example, when the user installs and then executes a large game, there may be a large amount of data to be downloaded from an external server when loading the game. Accordingly, a large amount of used data may be burdensome to a user who uses a limited data plan, and thus a function of temporarily releasing automatic communication network switching may be added. Therefore, when the selected game application is loaded, if the loading is completed and the actual game starts after temporarily downloading data through the Wi-Fi network, the processor 120 may perform a control to execute the game through the mobile communication network.

Meanwhile, the processor 120 may determine whether a predetermined application (for example, the game application) is executed in operation 705. When the predetermined application is executed, it is assumed that both the first communication module and the second communication module are activated. When the predetermined application is executed, the processor 120 may determine whether the application is an application set to limit automatic communication network switching on the basis of mapping information stored in the memory 130 in operation 710. When the application is not an application set to limit automatic communication network switching in operation 710, the processor 120 may execute the corresponding operation according to execution of the predetermined application, and a detailed description thereof will be omitted.
