Abstract: A portable communication device includes a subscriber identity module (SIM) card having a memory and a processor, a device-activity SIM application toolkit (SAT) application stored on the memory. When the device-activity SAT application is accessed by the processor and executed, the device-activity SAT application causes the SIM card to interface with the portable communication track device communication activity and/or device location, store device-activity data representative of the tracked device communication activity and/or device location, and upload the device-activity data to a remote device-activity server. The device-activity SAT application facilitates access to instantaneous device-activity data via device-activity data collection and uploading to a remote server accessible via the Internet.
