An indication unit for use with a portable wireless device is provided. The indication unit senses, via a proximity detector, that the user has returned to the vicinity of the portable wireless device sometime after the device has been in a stationary position and reminds the user of some important pending message through the use of a predetermined user indication. The portable wireless device may be a wireless telephone unit, a personal digital assistant (PDA), a short message service (SMS) device, a pager, or any other portable wireless device capable of storing a message of such a nature that a user would want to be notified and/or reminded of its existence in quick fashion upon returning to the vicinity of the wireless device.
