An electronic device is provided. The electronic device includes a touchscreen display; first communication circuitry to establish a short-range communication connection; second communication circuitry to establish a cellular communication connection; and a processor. The processor is adapted to establish, using the first communication circuitry, the short-range communication connection with a wearable device based at least in part on a graphical code being displayed on a display of the wearable device; based at least in part on a determination that an embedded subscription identity module (eSIM) profile is not installed on the wearable device, display, via the touchscreen display, a user interface (UI) to install the eSIM profile on the wearable device, the UI including one or more contract options associated with a cellular network service for the wearable device; receive, via the touchscreen display, a user input to select at least one contract option from the one or more contract options; and transmit, using the second communication circuitry, a service subscription request corresponding to the at least one contract option to a first server associated with the cellular network service, such that the eSIM profile corresponding to the at least one contract option is installed on the wearable device based at least in part on the service subscription request.
