ES478S is a 4G&D2C (LTE Cat.1) personal GPS tracker based on Starlink Direct-to-Cell (D2C) satellite technology, which allows the device to connect directly to the satellite in remote areas where terrestrial networks are unavailable or unreliable. Yet, in areas with terrestrial network coverage, the device can still communicate via ground-based cell towers. It is suitable for people who like outdoor activities such as hiking, climing, skiing, camping and traveling etc. ES478S also supports voice call for emergency situations.
