and if it is determined that it is impossible to perform the video communication with the external device, adapt the indication. ### Claim 4 (depends on 1) The electronic device of claim 1, wherein the processor is further configured to: if it is determined that it is possible to perform the video communication with the external device, control the display to display the indication such that the indication is activated; and if it is determined that it is impossible to perform the video communication with the external device, control the display to display the indication such that the indication is deactivated. ### Claim 5 (depends on 1) The electronic device of claim 1, wherein the processor is further configured to: perform the voice call with the external device via a first communication; in response to a service execution request during the voice call, determine whether a service connection can be established based at least in part on data communication quality and a result of whether it is possible to perform data communication with the external device via a second communication; and if the service connection is determined to a connection that can be established, control the display to display an image acquired through a camera and control the at least one communication circuit to transmit the acquired image to the external device via the second communication. ### Claim 6 (depends on 5) The electronic device of claim 5, wherein the processor is further configured to determine, during the voice call, whether the external device is affiliated with a service. ### Claim 7 (depends on 6) The electronic device of claim 6, wherein the processor is further configured to: determine whether the external device is affiliated with the service based on service subscription information of the electronic device; and if it cannot be determined whether the external device is affiliated with the service based on the service subscription information of the electronic device, request a server to identify whether the external device is affiliated with the service. ### Claim 8 (depends on 6) The electronic device of claim 6, wherein the processor is further configured to, in response to the service execution request, perform a data communication connection for executing the service with the external device. ### Claim 9 (depends on 6) The electronic device of claim 6, wherein the processor is further configured to: in response to the service execution request, control the at least one communication circuit to transmit a connection request message; wait for a reception of a connection response message corresponding to the connection request message, for a maximum waiting time; if the connection response message is not received within the maximum waiting time, terminate the voice call; and establish a voice and data communication connection via the second communication. ### Claim 10 (depends on 9) The electronic device of claim 9, wherein the processor is further configured to: if the external device is affiliated with the service, control the at least one communication circuit to transmit the connection request message; and if the external device is not affiliated with the service, terminate an execution of the service connection. ### Claim 11 (depends on 9) The electronic device of claim 9, wherein the processor is further configured to, in response to the reception of the connection response message, wait for a reception of a participation message for a designated maximum waiting time. ### Claim 12 (depends on 11) The electronic device of claim 11, wherein the processor is further configured to: if the participation message is not received within the designated maximum waiting time, determine that the service connection fails; and process a termination of the service connection. ### Claim 13 An operating method of an electronic device, the operating method comprising: performing a voice call with an external device via a first communication; in response to a service execution request being initiated based on a user input applied to an icon displayed on a display of the electronic device during the voice call, determining whether a service connection can be established with the external device based at least in part on data communication quality and a result of a determination of whether it is possible to perform data communication with the external device via a second communication;
