The invention relates to an SIM card electromagnetically controlled popup device, which structurally comprises an electromagnet base, a micro electromagnet, a rear ejecting mechanism, a card reader, a card reader clamping slot, an elastic piece buckle, an SIM card support and an SIM card support groove. The SIM card electromagnetically controlled popup device has the advantages that an SIM card mechanical withdrawing design at present is cancelled, and electromagnetically controlled popup is adopted. The SIM card electromagnetically controlled popup device adopts a mechanical-electrical integration design, is small in size, and does not affect normal designing and manufacturing of electronic equipment. The SIM card electromagnetically controlled popup device enables electronic equipment, such as a mobile phone, to be free of a card needle inserting hole beside the SIM card clamping slot, thereby realizing a seamless and integral design for the machine body. Popup of the SIM card support is controlled through electromagnetism, so that even if the electronic equipment is stolen, a stealer cannot control popup of the SIM card as long as the stealer cannot unlock the electronic device to acquire the system control authority under the premise that the equipment is not disassembled in a destructive manner. The stolen equipment is ensured to transmit and receive communication signals normally, and the possibility of finding back the electronic equipment after being lost is enhanced.
