Sprint and Verizon both recently started offering standalone GPS tracker devices that can report their exact position using cellular networks. AT&T already offers such a device. The devices use the new LTE Cat-M1 technology designed specifically for small, low-power devices that only need to transmit small amounts of data. Unlike Bluetooth-based tracking tiles, they do not need to be near the phone viewing the location, although the tracker device does need to be within the coverage area of the cellular network it's associated with. All of the tracker devices are roughly the size of a matchbook, are water-resistant, include Wi-Fi for enhanced location accuracy and efficiency, and have multi-day battery life. They are designed for tracking kids, pets, vehicles, and luggage, for example. Sprint's Tracker is made by Coolpad and features a light sensor and speaker. Its battery lasts 3-10 days and it's rated IP67 for dust and water. Sprint is charging $60 for the tracker and $5/month for service. The Verizon Smart Locator has battery life up to five days and an IP67 rating. Verizon charges $100 for the tracker with one year of free service, after which service is $3/month. AT&T offers the Samsung SmartThings Tracker, which has battery life up to one week and an IP68 rating. AT&T charges $100 for the tracker which includes one year of service. After the first year, service on the AT&T network is offered through Samsung, and runs $5/month or $50/year.
