Abstract
In accordance with some embodiments, an apparatus for privacy protection is provided. The apparatus includes a housing arranged to hold a personal communication device, a first subscriber identity module (SIM) interface, a second SIM interface, a personal communication device interface, and a controller. A portion of the personal communication device interface is shaped to mate with a SIM slot of the personal communication device, and the personal communication device interface includes a SIM emulator operable to couple the second SIM interface to the SIM slot of the personal communication device. Through operation of the personal communication device interface, the controller is operable to selectively couple one of the first SIM interface and the second SIM interface to the SIM slot of the personal communication device.
