Abstract: A portable terminal including a QWERTY keypad is capable of converting alpha-numeric inputs into a numeric only phone number. The portable terminal includes a controller that processes a phone number of a combination of letters and numbers. The controller can identify whether the input phone number contains letters. When the input phone number contains letters, the controller refers to a table for converting letters to numbers and converts the alpha-numeric phone number into a numeric phone number by converting the identified letters into corresponding numbers.
