Description This item is a practical and multi functional smartwatch, which adopts quality shell and silicone band. It is not only a watch which can display the time and date, but also can act as a GPS to mark its location. It also has SOS/ Anti-drop off alarm function. Specially designed for children and students to wear. Feature - Equipped with GPS global positioning system, it will show its location at any time to monitor the child position. - It supports micro SIM card so it supports making calls at any time, and it features a SOS button which is designed for emergency. It will ring the reserved phone number until it gets through. - You can set some creation areas for your kids on the APP maps, once kids leave these areas, the APP will alarm to remind you automatically. - The waistband is made of soft flexible silicone, easy to be folded to secure kids wirst without squeezing and breaking. - Note: There is no SIM card on the case so you need to take the battery out to settle the SIM card and this is not a difficult thing if you have some basic tools.
