D39B Kids Smart Watch

The D39B is a Plaspy compatible kids smart watch built for reliable communication, safety monitoring, and clear location tracking. With 4G voice and data connectivity, a 1.85-inch IPS display, and Android 8.1 under the hood, the D39B delivers real-time tracking and secure contact management in a durable, child-friendly form factor.

Designed for parents and guardians who want constant situational awareness without sacrificing ease of use, the D39B pairs its GPS, AGPS, LBS and Wi‑Fi positioning with secure voice and video calling so approved contacts can stay connected. When integrated with the Plaspy platform, the D39B becomes part of a single telemetry ecosystem—providing real-time tracking, alerts and reporting alongside other Plaspy compatible devices.

  • Accurate multi-source positioning using GPS, AGPS, LBS and Wi‑Fi for dependable real-time tracking.
  • 4G voice and data plus video calling for clear, immediate communication with approved contacts.
  • Child-friendly hardware: 1.85" IPS display and durable construction for everyday wear and visibility.
  • Smart features such as SOS emergency calling, class mode, pedometer and remote voice monitoring (feature availability depends on software configuration).
  • Runs Android 8.1 with 1GB RAM and 8GB ROM to support essential apps and secure messaging where permitted (e.g., WhatsApp).

How It Works with Plaspy

When the D39B is connected to the Plaspy platform, its location and communications updates are sent to Plaspy’s real-time tracking engine so parents and administrators can view position, status and events on a single map. Plaspy normalizes the device’s telemetry and presents it alongside other compatible trackers—helping you manage personal safety devices and larger fleets from the same interface.

  • Voice and video call session indicators and approved-contact lists for secure communication
  • Activity data such as pedometer steps and basic status notifications (subject to configuration)
  • Remote monitoring events (remote voice monitoring and class mode notifications where enabled)

Why Choose This Tracker with Plaspy

Choosing the D39B as a Plaspy compatible device delivers a straightforward path to centralized, real-time tracking and communications. The D39B’s multi-source positioning (GPS/AGPS/LBS/Wi‑Fi) and 4G connectivity ensure location and status updates arrive quickly on the Plaspy dashboard, while Android 8.1 and built-in calling/video features allow familiar communication options. For organizations that already use Plaspy for telemetry, fleet management or larger asset tracking, adding D39B watches lets you manage personal safety devices alongside vehicle and equipment telemetry—without fragmenting your monitoring workflow.

While the D39B is optimized for child safety rather than vehicle telemetry, integrating it into a Plaspy ecosystem provides consistent alerts, consolidated logs and unified reporting. This makes it easier to maintain secure communications, support rapid responses to SOS events, and consolidate data across device types—whether you are tracking people, assets or managing broader telemetry for fleet operations. For families and care teams seeking reliable, Plaspy compatible GPS tracker capabilities with modern communication features, the D39B provides a pragmatic, easy-to-deploy option.
