Abstract
A mobile phone has a display and a keypad which comprises a plurality of keys. Each key has associated with it a plurality of different symbols. The keypad is used to enter symbols in the form of Pinyin strings (25) into the display which are then used to determine a candidate list (26) of Chinese characters which are presented in the display. Symbols are entered into the display by pressing respective keys once or more than one times in rapid succession. Selection of a symbol is only permitted if it corresponds to a valid Pinyin string (25), either in isolation or in combination with one or more symbols entered in a previous selection. Characters chosen from the candidate list are entered into a message (24) in the display.
