An electronic device and method are disclosed herein. The electronic device may include a housing, a socket disposed in the housing, a tray insertable into the socket, and into which at least one of a storage medium card and a subscriber identity module (SIM) card is insertable, a communication circuit disposed in the housing, a processor disposed in the housing and electrically coupled to the communication circuit and a memory electrically coupled to the processor. And the memory may store instructions executable by the processor to cause the processor to perform a communication through the communication circuit by using a first SIM card inserted in the tray, while the tray is inserted into the socket, in response to detecting removal of the tray from the socket, deactivate at least part of the communication circuit, in response to detecting re-insertion of the tray into the socket, detecting whether a particular SIM card inserted into the re-inserted tray matches the first SIM card and determine whether to perform initialization of the communication circuit based at least partially on whether the particular SIM card matches the first SIM card.
