Radian Screen 4G Kids GPS Tracker D40

Product Description


Overview

Introducing the 4G Radian Screen Kids GPS Tracker D40, a premium smart watch tailored for kids who value comfort, style, and safety. Featuring a sleek 1.72inch Curved IPS Screen, powerful 800mAh battery, and 1GB+16GB large memory, this device combines high-performance safety tools with engaging entertainment functions. Supported by 4G/LTE network and GPS+LBS+WiFi Positioning, the D40 lets parents monitor their child’s location in real time, while the IP67 waterproof design and durable build make it ideal for active kids. With dual camera, two-way video call, and popular social app support, the D40 is more than a tracker—it’s a smart companion for kids’ daily adventures.

Core Features

Advanced Real-Time Positioning

The D40 uses GPS+LBS+WiFi Hotspots Positioning to deliver accuracy of less than 5M, ensuring parents can track their child’s location via the Beesure GPS App anytime. The app also displays History Route, so you can review past movements, and supports up to 3 valid Geo-fence/Safety Zone alerts—triggering SMS notifications when your child leaves the set area. Real-time Google Map integration makes location checking intuitive and precise.

Crystal-Clear Two-Way Communication

Stay connected with Two-way Video Call and Voice Call features, powered by the 0.3M dual camera and built-in speaker/microphone. Kids can make emergency calls with the SOS Emergency Call button (3-second press) to pre-set contacts, while parents can use Voice Remote Monitoring to listen in on the child’s surroundings discreetly. The watch rejects unknown calls, ensuring safe communication with trusted contacts only.

Ergonomic Radian Screen Design

The 1.72inch Curved IPS Screen (320×380 pixels) offers a comfortable viewing experience with 2.5D high-definition display, reducing eye strain for long-term use. The radian design fits snugly on kids’ wrists, while the lightweight (54.5g) PC+ABS casing and soft strap ensure all-day comfort. The screen’s brightness and volume are adjustable, adapting to different environments.

Large Memory & Versatile Functions

With 1GB+16GB Memory, the D40 supports a Music Player, Video Player, and Voice Recorder, compatible with formats like MP3, MP4, and 3GP. Kids can enjoy favorite content or educational materials on the go. It also features Social App Support (WhatsApp, YouTube, TikTok, Spotify, etc.), Math Game, Stop Watch, and Google Translate, blending entertainment with learning. The Pedometer, Calorie Counter, and Sleep Monitoring tools help track kids’ health habits.

Parent-Friendly Control Tools

Class Mode (Do Not Disturb) mutes notifications during school hours, preventing distractions. Parents can manage the watch via the Beesure GPS App, including Remote Shutdown/Restart, Find the Watch, and Batch Sending Photos. The Night Power Saving Mode extends battery life, while low battery alerts ensure you never miss a chance to recharge.
