ABSTRACT:
A recyclable cellular telephone is disclosed having an inner rigid cellular electronics supporting frame member surrounded by a replaceable outer cover. The telephone is acquired having a limited period of use. The electronics of the telephone operate to disable the telephone following expiration of the period of use. Following expiration of the period of use, the telephone is returned for refurbishment where the outer cover is stripped and replaced and the electronics tested before being recycled with a new period of use for an another acquisition. The cellular network supporting telephone operation also monitors the period of use, disabling telephone access to the network following expiration. Directory numbers are selectively assigned to the recyclable telephones from a pool of available numbers, with assigned numbers returned to the pool after expiration of a predetermined period or telephone deactivation for re-use by another recyclable telephone. The recyclable telephones are activated and deactivated in a number of ways, including through the use of a separate activation and deactivation station which communicates with the telephones over a radio frequency communications link.
