and in response to the reception of the end command, returning, by the mobile communication device, the voice input unit to the inactive state;

the method further comprising:

determining, by the mobile communication device, whether or not the first voice command received from the user has been input to the voice input unit within a predetermined time;

if the voice command is determined not to have been input within the predetermined time, repeatedly outputting an audible signal or a visual display or a vibration to notify the user that the message has been received.

receive a message and display a message reception indicator,

in response to the reception of the message, activate the voice input unit from the inactive state to allow the user to input voice commands therethrough,

replace message reception indicator with a voice input activation indicator to indicate that the voice input unit has been activated,

receive a first voice command from the user through the voice input unit, the first voice command being one of a plurality of voice commands stored in a memory,

in response to the reception of the first voice command, establish a phone call to a sender of the received message,

receive a second voice command from the user through the voice input unit, wherein the second voice command is an end command, and

in response to the reception of the end command, return the voice input unit to the inactive state;

wherein the controller is further configured to determine whether or not the first voice command received from the user has been input to the voice input unit within a predetermined time;

wherein, if the voice command is determined not to have been input within the predetermined time, the controller is configured to repeatedly output an audible signal or a visual display or a vibration to notify the user that the message has been received.
