Downloading of number assignment module designation parameters into a memory circuit of a mobile data telephone set utilizes the built-in voice band modem of the set so that service authorization codes and activation can be entered remotely into the subscriber's set thereby initiating cellular service or changing the type of service provided. As described, a cellular mobile subscriber first calls a remote cellular service provider center to establish a voice communication channel between the set and the center. Next, the modem of the set is selectively bridged onto the voice communication channel to achieve data transfer between a source of data located at the remote center and the subscriber's modem. The foregoing enables the remote programming of subscriber's authorization and information into the memory circuit of the mobile data telephone set.
