A new Samsung device with model number EI-T5900 has received certification from South Korea's National Radio Research Institute.
The filing describes it as a small wireless device without an official name, but the model number aligns with previous SmartTag generations.
The current Galaxy SmartTag 2 uses EI-T5600, while the original SmartTag was EI-T5300, making it highly likely this is the Galaxy SmartTag 3.
Rumors suggest a design shift to a squircle shape—a square with heavily rounded corners—departing from the pill-shaped SmartTag 2.
This new look would complement Samsung's rounded design language seen in One UI icons and recent Galaxy Watches.
Samsung has not officially confirmed the SmartTag 3, and details on pricing, features, battery life, and launch date remain undisclosed.
Radio certification is typically one of the final steps before a wireless product can be sold in South Korea, indicating progress.
More information could emerge in the coming weeks or months as Samsung prepares its next accessory lineup.
For reference, the Galaxy SmartTag 2 features Bluetooth Low Energy 5.3, ultra-wideband, a 120-meter range, IP67 rating, and a replaceable CR2032 battery lasting up to 500 days.
