Abstract
A mobile communication terminal device such as a cellular telephone is provided with a preliminary identifier stored in memory. The identifier allows access to a cellular network for verification and provides essentially unique identification by the network, but is insufficient to allow further use of the network. During verification, the identifier is analyzed by a cellular network processor and a determination is made whether the cellular telephone should have restricted access to the network. Upon favorable completion of the identifier analysis, a signal may be transmitted to the cellular telephone that allows the cellular telephone to have less restricted access to the network.
