An embodiment of the present disclosure discloses a processing method and a system of a mobile terminal. The method comprises: receiving a card slot ejecting command when determining that the card slot is dosed; generating a control message according to a card slot ejecting command, and sending the control message to a mechanical device; and ejecting the card slot out through a first sensor of the mechanical device. The mechanical device automatically controls the ejecting of the card slot, and it is not needed to manually take out the card slot by using a card pin. The operation is convenient, and time is saved.

A packaged cellular modem system includes a capacitor for receiving power from a DC power source, a DC-to-DC converter coupled to capacitor electrodes, a cellular modem coupled to the converter output and to an antenna, and an IS barrier circuit coupled to a modem output. A microcontroller coupled to a boost regulator has its output coupled to electrodes. A metrology jumper is between the microcontroller and ground. An encapsulation material provides a potted area for the capacitor, converter, modem, IS barrier circuit and microcontroller. A SIM card is coupled to the modem by the IS barrier circuit. LED's are coupled to the microcontroller. The SIM card and LEDs are in a non-potted area. A transparent SIM card access cover over the SIM card and LEDs enables exposing the SIM card.
