Abstract: A method for transmitting a dual tone multi frequency (DTMF) and an electronic device thereof. In the method, a number input event is detected during communication. When the number input event is detected, a numerical keypad is displayed. At least one number is received via the numerical keypad. The received at least one number is stored in a buffer. When a transmission event is detected, at least one DTMF corresponding to the number stored in the buffer is transmitted to a base station.
