Yes, but only some older Samsung watches. The original Galaxy Watch, Galaxy Watch Active and Active2 are listed by Samsung as compatible with iPhone; Galaxy Watch4 and newer models are not officially compatible with iOS. Galaxy Watch3 is a regional edge case: Samsung’s UK and Canadian support pages list it, while its U.S. page does not. If you’re buying a new watch for an iPhone, don’t buy a current Galaxy Watch expecting it to pair.
Compatibility information below reflects Samsung’s support documentation checked August 18, 2026. Check your exact model and region before buying or trying setup: “Galaxy Watch” covers several generations with different operating systems and phone support.

Samsung’s U.S. compatibility guidance lists the original Galaxy Watch, Galaxy Watch Active and Active2 for iPhone 5 or later running iOS 9 or later. That is a published minimum, not a guarantee that an old watch will still set up reliably with every current iPhone, app version or regional App Store. Samsung also says iPad and iPod touch are not supported for these connections.

Why Watch4 and newer do not pair
The dividing line is the watch’s platform, not just its age or price. Current Galaxy Watch models use Wear OS and rely on Google Play services; Samsung says those services are not supported on iOS. As a result, the official Galaxy Wearable setup and companion experience required by these watches is not available for iPhone. See Samsung’s explanation of iOS compatibility.

Bluetooth by itself does not make a watch compatible. A device might show up as a Bluetooth signal or expose an isolated function through an unofficial method, but that is not the same as supported setup, app management, notifications, health syncing and updates. An LTE version does not change the operating-system requirement: cellular service does not replace the companion-phone setup.
What iPhone do you need for an older compatible watch?
Samsung’s stated baseline for the legacy models it lists is iPhone 5 or later with iOS 9 or later. Samsung warns that connections involving iPhone 6S or 6S Plus on iOS 10 or later may be unstable. Because those requirements date from an earlier software era, check these points before relying on a used watch:

How to pair a compatible older Galaxy Watch with an iPhone
This general flow is for models Samsung lists as iPhone-compatible. It does not make Watch4 or a newer Galaxy Watch compatible; app availability alone is not proof that a particular watch can pair.
- Charge and turn on the watch. If it was previously paired with another phone, back up anything important and be prepared to reset it; a reset can erase watch content.
- Install Galaxy Wearable from the Apple App Store, as Samsung directs for compatible models.
- Turn on Bluetooth on the iPhone and keep the devices close together.
- Open Galaxy Wearable and select the relevant watch model. Follow the app’s prompts rather than starting with a manual Bluetooth pairing in iPhone Settings.
- Choose the watch when it appears, then check that the pairing code shown on both devices matches.
- Grant only the permissions you want to use, such as Bluetooth, notifications, contacts or health-related access, when prompted.
- Sign in to or create a Samsung account if the app requests it, then let setup and any available updates finish.
App labels and available steps can vary by version, country and watch. If your exact model is absent from the app or setup stops, do not assume that a different Bluetooth pairing route will provide full compatibility.

What works—and what may be limited—on iPhone
Samsung’s published feature information does not provide a complete, model-by-model iPhone feature matrix. Treat a successful pairing as a starting point, not a promise of Android-level functionality. The experience may be more limited for app installation and watch-face management, Samsung Health synchronization, message replies, calls and call history, music transfer, payments, firmware updates and voice-assistant functions. Exact support can depend on the watch, iPhone, app version and region, so verify any feature you consider essential before buying.
Health features deserve particular care. Samsung says Samsung Health Monitor features—including ECG, irregular-heart-rhythm notifications and sleep-apnea features—are restricted to Samsung phones; its documentation also ties ECG and blood-pressure features to Samsung Health Monitor and a Samsung Galaxy device. Do not buy an older watch expecting those features to work through an iPhone. These functions are device- and platform-dependent and should not be treated as a diagnosis.

If your watch is already paired to an Android phone
An older iPhone-compatible model may need to be reset before it can pair with an iPhone. Back up important data first and follow the watch’s reset instructions, since resetting can erase stored content. A Galaxy Watch4 or newer remains incompatible with iPhone even after you switch phones or reset it.

Troubleshooting an older compatible watch
- Check model support first. Confirm the watch is on Samsung’s iPhone-compatible list for your country, especially if it is a Watch3.
- Use the companion app. Install the current Galaxy Wearable app available for that model and start setup there, not from iPhone Bluetooth settings.
- Refresh the connection. Restart both devices, toggle Bluetooth off and on, and keep them close during setup.
- Clear old pairings. Remove stale Bluetooth pairings and make sure the watch is not still connected to another phone.
- Reset only if needed. If the watch was used with Android, back up what you can and reset it before trying again.
- Check app and firmware availability. If the app cannot find the device or no longer offers setup for it, a static compatibility page may not reflect a smooth current setup path.
- For iPhone 6S/6S Plus instability, Samsung’s UK guidance suggests unpairing other Bluetooth devices and toggling Bluetooth.
Are unofficial workarounds worth it?
There is an important difference between official pairing and an unofficial Bluetooth or third-party bridge. A bridge app may claim to pass selected notifications or data, but that does not establish dependable support for setup, calls, health syncing, app installation or updates. App availability, permissions and reliability can change, so do not treat an unverified bridge as a reason to buy an incompatible watch.
Better smartwatch choices for iPhone owners
- For the simplest iPhone experience: An Apple Watch is designed to work with iPhone and offers the strongest integration for notifications, calls, messaging and Apple services. Apple’s current U.S. buying information says Apple Watch SE 3, Series 11 and Ultra 3 require iPhone 11 or later with iOS 26 or later; confirm requirements for the specific model before purchase. The SE line is the more budget-conscious option, while Series and Ultra models target different feature and outdoor-use priorities. Check Apple’s current watch compatibility and buying details.
- For training and cross-platform fitness: Garmin watches can pair with iPhone for smart notifications. The Forerunner 570 is aimed at performance-focused runners and triathletes, with training and GPS priorities rather than Apple-level iMessage, Siri or app integration. See Garmin’s product announcement and check the exact feature list that matters to you.
- If you already own an old Galaxy Watch: Trying to pair it may be reasonable, but treat it as a legacy device and verify app support and essential features first. It is a risky default purchase for someone who wants long-term support or Samsung Health Monitor features on iPhone.
Compatibility and product requirements can change. The links above lead to manufacturer guidance; check them for your country and exact model before purchase.
