A system and method for communicating wirelessly from a mobile device to a remote receiver station is disclosed. The system includes a controller configured to monitor a status of the mobile device and, upon an initiation event, initiate a data transfer process to wirelessly communicate data to the remote receiver station. The system also includes a voice-band modem that, upon initiation of the data transfer process. The voice-band modem is configured to receive data for transfer to the remote receiver station, encode the data to form a series of encoded packets, and transmit the encoded packets to the remote receiver station using a first modulation scheme. Thereafter, unless an indication that the series of packets has been received by at the receiving station is provided, the voice-band modem automatically retransmit the encoded packets to the remote receiver station using a second modulation scheme.
