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.

Methods, systems, and devices for recovery techniques for subscriber identification module (SIM) detection error are described. A user equipment (UE) may determine an operating mode for the UE based on a SIM card switch occasion. The SIM card switch occasion may be a “hotswap” occasion of a SIM card while the UE is powered on. The UE may power a SIM card associated with the UE based on the operating mode for the UE and a previous status of a SIM slot associated with the UE. The UE may detect a presence of the SIM card in the SIM slot based on powering the SIM card. The UE may set a SIM sensing operation at the UE based on the detected presence of the SIM card.

According to various embodiments disclosed in the present document, an electronic device may comprise: a housing comprising an insertion hole formed through one side thereof, a first tray for containing, among a subscriber identity module (SIM) and a memory card, at least the subscriber identity module, the first tray being inserted into the housing through the insertion hole and contained therein in an attachable/detachable manner; and a second tray for containing, among the subscriber identity module and the memory card, at least the memory card, the second tray being inserted into the housing through the insertion hole and contained therein in an attachable/detachable manner. While being contained in the housing, the first tray and the second tray may be at least partially positioned on the same plane, and at least a part of the second tray may be exposed to the outer surface of the housing while closing the insertion hole. The electronic device described above may vary according to embodiments.

A portable electronic device is provided. The portable electronic device includes a front glass cover that forms the front of the electronic device, a back cover that forms the back of the electronic device, a bezel that surrounds the space formed between the front and back covers and is formed integrally with, or separately from, the back cover, wherein the bezel has a first opening with a first size and a second opening with a second size smaller than the first size, the second opening being disposed adjacent to the first opening, a display device that is located in the space and has a screen area exposed through the front cover, a tray structure that is inserted into the space through the first opening and is detachably mounted, the tray structure having a recess in which a memory card and/or a subscriber identification module (SIM) card is received, a first member that holds the tray structure when the tray structure is inserted into the space and a second member that allows a first member to release the tray structure by the press of an external member that is inserted through the second opening, and a waterproof structure that includes a first portion that is movably inserted into the second opening, a first end portion that makes contact with the second member by the press of the external member, and a second end portion that is pressed by the external member.

A mobile terminal is provided, which includes: a housing, having a tray installation hole; a circuit board, disposed inside the housing; a tray retention portion, disposed inside the housing, where the tray retention portion faces toward the circuit board; a card holder, disposed on the circuit board; a tray, movably disposed in the tray installation hole and movably mating with the tray retention portion, at least the tray or the housing is provided with an ejection hole; and a toggle piece, rotatably disposed at the tray retention portion and located between the card holder and the ejection hole, one end of the toggle piece is an ejector pin action receiving end, the other end of the toggle piece is a tray ejection end, and the tray ejection end is used to apply an ejection force to the tray after a force is applied to the ejector pin action receiving end.

A waterproof card holder includes a card holder frame and a cover plate located at top of the card holder frame. The waterproof card holder includes a sleeve integrated with and extending from an inner side of the cover plate and a through-hole penetrating through the sleeve and the cover plate. A waterproof mechanism is accommodated in the sleeve. The waterproof mechanism includes a main body, a first end portion located inside the sleeve, a second end portion protruding from the sleeve, and a waterproof ring located on a periphery of the main body and close to the first end portion. The waterproof ring and the sleeve form a sliding sealing structure therebetween.
