When a control section 8 of a mobile communication device detects a voltage drop of a battery during wireless data communication through packet transmission, the control section temporarily stops transmission in the state where reception is maintained. The mobile communication device receives power from a data terminal connected to the mobile communication device through a modem card. When an exchange of batteries is ended and a battery voltage is recovered, transmission is resumed. Transmission data during a period when the transmission is stopped, is stored in a RAM in the modem card. |
