UBSCRIBER IDENTITY MODULE (SIM) CARD
Each Subscriber Identity Module is programmed with specific identification features for a unique
user, allowing the device that contains a module to be used for such things as online banking and
purchasing that require a secure means of identification. They can be swapped between other
GSM devices, so the Subscriber Identity Module owner isn't confined to a single device.
Teletrac will use the SIM Cards as a quick way to move specific programming information from
one location unit to another. The SIM Card will contain information such as location schedules,
landmarks, service reminders etc. When the hardware of a locator unit goes bad an installer will
replace the hardware and take the SIM Card from the broken device and place it in the new
device. This will move all the programmed information and alleviate the need to reprogram units.
