Abstract: An apparatus receives, from a user terminal of a user using a SIM provided by a carrier having a communication infrastructure, a diagnosis request with respect to the SIM. In accordance with the diagnosis request, the apparatus, with respect to one or a plurality of instances included in the communication infrastructure, transmits an acquisition request for condition information concerning the condition of a wireless communication service associated with the SIM to be diagnosed. Each of the instances that have received the acquisition request acquires the condition information with respect to the SIM to be diagnosed, and transmits the condition information to the apparatus. The apparatus performs a diagnostic process on the basis of the received condition information, and transmits to the user terminal display information for a diagnostic result display screen based on the condition information.
