Does Nintendo DS Have a Tracking Device? No — Here's Why

No. The Nintendo DS (all models) has no GPS, cellular, Wi-Fi triangulation, or any hardware capable of location tracking. It only communicates via local wireless (ad-hoc) and, on DSi/3DS, standard Wi-Fi for internet — no positioning capability.

If a DS is lost, recovery relies on honest finders or serial-number registration with Nintendo (for warranty), not tracking.
