"The SPOT X 2-Way Bluetooth Satellite Messenger helps you stay in touch when you're off the grid or beyond reliable cellular coverage. Connect the SPOT X 2-Way Bluetooth Satellite Messenger to your smartphone via Bluetooth through the SPOT X app to access your contacts and communicate easily with family, friends, or directly with search-and-rescue services in a life-threatening situation. If preferred or when necessary, SPOT X can be used as a standalone communication device. SPOT X has its own dedicated U.S. mobile number, so others can message you directly at any time. Unlike ordinary, basic wireless communicators, this SPOT X messenger sports a 2.7"" backlit display, IP67-rated high resistance to dust and water, and an illuminated Qwerty keyboard. It can run up to 240 hours in 10-minute tracking mode on the internal, rechargeable lithium battery.Manufacturer model #: SPOT-HD-X-B.
