A fold-type cellular phone has a top unit, a bottom unit and a hinge coupling together the top unit and the bottom unit while allowing the top unit to turn and swivel with respect to the bottom unit. The top unit is first unfolded from a first folded position to an attitude angle of 160 to 170 degrees, and swiveled by 180 degrees to be folded onto the bottom unit in a second folded position at an attitude angle of 180 degrees. The swivel movement of the top unit causes a cam assembly to turn the top unit from the attitude angle of 160-170 degrees to an attitude angle of 180 degrees in the second folded position, thereby allowing the top unit to assume a suitable attitude with respect to the bottom unit.
