Abstract: A device management method, is disclosed in which available features on a slave mobile device are managed (monitored or controlled) by a slave manager module commanded by a master device through secure messages exchanged between the two devices using respective electronic messaging capabilities on the two devices. Selection of the features of the slave mobile device to be controlled or monitored is facilitated on the master device through a master manager module resident thereon. The features that are controlled or monitored may comprise any user-accessible feature incorporated or installed on the slave mobile device and user access to the feature may be prevented according to at least one criterion, such as: date of use, time of day of use, number of times of use, originator and recipient. User access to the feature may be prevented access to the user-accessible feature when usage limitations for the feature have been reached.
