Trackimo Slim GPS Tracker 3G Small, lightweight, high-precision, high-functionality GPS device with global roaming support. Also functions as an IoT gateway using communication features. Thank you for viewing. I purchased this on Amazon. It is used in conjunction with an app. The size is like a card, but it is a bit thick. The box has a small tear, but all accessories are included, and there is also a manual. This is a sale of the device only, so please make your own contract. There is some wear and tear, so please understand before purchasing.
