A predictive data entry method permits a user of a device to efficiently enter data using a keypad where each of a plurality of keys represents a plurality of different characters. When the user presses one of the keys representing multiple characters, the predictive data entry method determines the character within the multiple characters most likely desired by the user. Thus, in most instances, a single key stroke is sufficient to select the desired character.
