Samsung's Galaxy SmartTag3 will go on sale in the U.S. by early November, and the company is pitching it as the first SmartTag that works with both Galaxy phones and iPhones. A single tag costs $29.99, while a four-pack runs $99.99, and buyers can pick White or Black. The tracker keeps the IP67 water and dust resistance of earlier models.
The headline change is cross-OS support. Samsung says SmartThings Find lets users see a tag's location, share it with others, and run Search Nearby on supported devices. That said, three features do not carry over to iOS: Compass View, Ring Phone, and Left Behind Alert. Samsung says feature availability may vary by platform, and it points buyers to the SmartThings website for the compatible device list.

Compass View is the marquee locating tool. Samsung says it shows distance and direction at a range of up to 60 meters, roughly three times what the previous generation managed. Bluetooth 6.0 Channel Sounding drives that distance and direction readout, while ultra-wideband adds precision when the tag is close by. Samsung does not name a specific UWB chip or version.
Finding a lost tag leans on the Galaxy Find Network, which Samsung says includes more than 900 million participating Galaxy devices. The company claims location updates arrive faster after a tag disconnects. New software features include Place Notification, which alerts you when the tag enters or leaves an area you define, Location History, which shows where a tag has been, and Movement Detection Alert, which fires when the tag moves. Left Behind Alert warns when your phone loses its connection to the tag.
A few practical extras round out the package. Lost Mode uses NFC so anyone who scans a found tag can see your contact details or a message. The tag's button can trigger SmartThings routines. Location data is encrypted, according to Samsung. The company also introduced two official accessories, a Silicone Case with a keyring and a Loop Case, sold separately with color and availability varying by carrier and retailer.
Samsung's safety guidance is worth repeating. A detached tag can be a swallowing hazard for children and pets, so the company advises inspecting it regularly and stopping use if it is damaged, deformed, or detached, and contacting emergency medical services or a veterinarian immediately if it is swallowed. Samsung also notes that battery life figures come from simulated internal lab tests.
The launch lands in a busy stretch of Galaxy announcements. Samsung recently began its One UI 9 rollout, starting with the Galaxy S26, S26+, and S26 Ultra, and it unveiled the Galaxy Tab S12 series, including the Tab S12 Ultra and Tab S12+. The company has also been promoting Smart Switch, which moves contacts, photos, videos, messages, apps, and settings from an iPhone or Android phone to a Galaxy device.
Several details remain unannounced. Samsung gave no exact on-sale date beyond early November, named no carrier or retail partners, and offered no preorder window or preorder pricing. It also did not publish the tag's weight or dimensions in absolute units.
