A film layer for a mobile station that allows the appearance of the mobile station to be easily changed. The layer is thin enough to allow it to be positioned between the plungers on a plunger mat and the keys on a key mat of the mobile station. Flexibility of the film layer allows a key press to be transmitted through the film insert to one of the plungers, which in turn compresses a contact on a printed wiring board. Flexibility may be due to perforations around the keys of the key mat. Preferably, the film layer includes some visually detectable characteristic, such as a color, that is visible through openings or translucent portions of the key mat. The film layer may be constructed of various materials, such as paper, elastomer, polymer or electric luminescent materials which can be interchangeably inserted into the mobile station to change its appearance.
