Invoxia Cellular GPS Tracker uses the brand new LTE-M (or LTE Cat M1) network, supported by AT&T in the USA. Your GPS Tracker will thus work anywhere where there is AT&T 4G coverage, except in the five territories (Puerto Rico, the U.S. Virgin Islands, Guam, the Northern Mariana Islands, and American Samoa).
☝️ Please note that the product might not work where there is typically no cellphone coverage: in the mountains, in underground parking lots, within very thick walls etc.
💡 Contrary to Bluetooth-only trackers, Invoxia Cellular GPS Tracker is completely standalone and will work even where there are no smartphones around.
