Abstract: An electronic device includes a display, communication circuitry performing wireless connection with an external electronic device, a processor operatively coupled with the display and the communication circuitry, and a memory operatively connected with the processor. Based on executing instructions stored in the memory, the processor is configured to control the electronic device to receive information on a first notification message generated within the external electronic device using the communication circuitry. Based on instructions stored in the memory being executed, the processor controls the electronic device to display the first notification message through the display. Based on the instructions stored in the memory being executed, the processor is configured to control the electronic device to receive one or more second notification messages which have been generated within the external electronic device prior to the first notification message. Based on instructions stored in the memory being executed, the processor is configured to control the electronic device to display, in response to an input, the second notification message in at least a portion of the display.
