In certain embodiments, an electronic device may include a subscriber identification module (SIM) tray allowing at least one SIM card to be loaded in a row, a SIM detector detecting the at least one SIM card, and a processor operatively connected to the SIM detector. The processor may be configured to detect, through the SIM detector, an insertion of the SIM tray in which the at least one SIM card is loaded, to determine whether the insertion of the SIM tray is completed within a predetermined time, and to perform a SIM reset operation corresponding to the at least one SIM card in response to the completed insertion of the SIM tray. Other embodiments are possible.

An electronic device includes a card interface and a processing module. The card interface is electrically connected to the processing module, and a SIM card or a memory card may be inserted into the card interface. The card interface includes 8 springs, where N>1; when a memory card is inserted into the card interface, the memory card is electrically connected to the processing module; and when a SIM card is inserted into the card interface, the SIM card is electrically connected to the processing module, and one metal pin of the SIM card is electrically connected to a first spring in the N springs and one spring adjacent to the first spring. The processing module is configured to determine, based on at least a level of the first spring, that an inserted card is a SIM card or a memory card.

A button assembly includes a pressing element, a tray, and a locking structure fastened between the pressing element and the tray. One side surface of the pressing element is recessed inward to form an accommodating space. The pressing element opens at least one first upper fixing hole. A bottom surface of the pressing element is recessed upward to form a first accommodating slot. The first accommodating slot opens at least one first opening. The tray of which one side is connected with the pressing element. The one side of the tray has a base portion mounted in the accommodating space. The base portion opens at least one second opening. A bottom surface of a peripheral wall of the at least one second opening is recessed upward to form at least one locking slot. The locking structure includes at least one locking element and an elastic arm.

This Application describes efficient cellular service transfer mechanisms to move cellular services that are based on cellular service credentials, e.g., eSIMs, between accessory wireless devices under various scenarios, including in some embodiments transfer of multiple eSIMs. The first and second accessory wireless devices and the primary wireless device are associated with a common user account. Transfer of credentials for cellular service access can occur between two accessory wireless devices via the primary wireless device, where the primary wireless device and the accessory wireless devices interact with applicable network-based servers.
