Network use method using virtual SIM and apparatus therefor

An electronic device, comprising:

• a processor configured to execute a roaming application;
• a communication circuit configured to enable a first subscriber identity module (SIM) and to communicate with a network based on the first SIM and to communicate with a plurality of networks based on a third SIM which provides a network service different from the first SIM and a second SIM;
• and
• a memory configured to store data associated with the roaming application,
• wherein the processor is further configured to:
• download the second SIM corresponding to the roaming service product from a server when a roaming service product is selected in the roaming application, wherein the first SIM is a SIM card and the second SIM is a virtual SIM to be stored in memory of the electronic device after the download;
• enable an activation menu of the roaming service product included in the roaming application, based on a mobile country code (MCC) obtained by a network search being identical to an MCC included in the second SIM;
• allow the communication circuit to enable the second SIM if purchase of the roaming service product through the enabled activation menu is completed;
• allow both the first SIM and the second SIM to be active simultaneously for different functions, so as to allow performance of a voice call based on the first SIM and data communication based on the second SIM;
• provide a selection screen for the first SIM and the third SIM;
• control to disable a SIM selected between the first SIM and the third SIM and to enable the second SIM;
• receive information about at least one of a residual time and residual data usage of the roaming service product from at least one server;
• and
• provide a menu for updating or extending the roaming service product in the roaming application if one or more of the residual time or the residual data usage meets a predetermined condition.
