The electronic device includes a display, a memory configured to store virtual reality content, a processor configured to play back binocular image data based on the virtual reality content on the display, and a communication circuit configured to communicate with an external device. At this time, the processor is configured to determine whether the virtual reality content is stored in the external device and to determine data to be transmitted to the external device based on the determined result.
