LT21 4G Kids GPS Smartwatch – Video Call, SOS, IP67 Waterproof & Location Tracker

Stay Connected. Stay Safe. Stay in Control.

Every parent knows the feeling — that moment when your child is out of sight and you wish you could just check in. The LT21 4G Kids GPS Smartwatch is designed to give you that reassurance, every single day. With real-time GPS location tracking, two-way video calling, and a dedicated SOS emergency button, this watch keeps your child connected to you and you connected to them — wherever they are.

The 4G LTE SIM card slot means this watch operates as a standalone phone on your child's wrist. They can make and receive calls, send messages, and video call you directly from the watch — no smartphone required. The Setracker app on your phone gives you a real-time view of your child's location at all times, with geofencing alerts that notify you the moment they leave a designated safe zone.

The SOS button is the feature that matters most in an emergency. With a single press, your child can send an immediate alert to pre-set emergency contacts, triggering a call and sharing their GPS location instantly. It's a simple, reliable safety net that gives both parent and child the confidence to navigate the world more independently.

The 1.4-inch IPS touchscreen with 240x240 resolution is bright, clear, and easy for small hands to navigate. The cute, child-friendly design makes it something kids actually want to wear, while the silica gel band is soft, comfortable, and durable enough to handle the rigours of an active childhood. The IP67 waterproof rating means splashes, rain, and the occasional puddle are simply not a concern.

Built-in WiFi connectivity supplements the 4G connection, ensuring your child stays reachable even in areas with strong WiFi coverage. The 0.3MP camera lets them capture and share moments with you, and the built-in flashlight adds a practical safety feature for low-light situations. The alarm clock and step counter add everyday utility, and the watch supports 14 languages for global families.

CE certified, powered by a MediaTek 8521E processor with 2GB RAM and 4GB storage, and compatible with all networks. This is the smartwatch that gives your child independence and gives you peace of mind — the perfect balance for modern family life.
