A mobile station including a cover assembly and a wireless telecommunications signal receiving and generating assembly. Included in the cover assembly is a belt that substantially extends around the signal receiving and generating assembly, and a connector to hold the belt closed about the signal receiving and generating assembly. The belt includes a pair of side edges which define side openings through which the signal receiving and generating assembly can be accessed. Advantageously, the belt is easily exchanged with other belts so as to vary the appearance of the mobile station. Further, the side edges are easily gripped by a user holding the mobile station. In another aspect, the belt includes an integrated key pad which overlies a plurality of key contacts of the signal receiving and generating assembly.
