In a significant advancement for wearable technology and satellite connectivity, SpaceX's Starlink has expanded its Direct to Cell service to support select Apple Watch models. This development allows users in remote areas or regions with poor cellular coverage to send and receive text messages directly via satellite, marking a new era in always-connected wearables. The feature, which leverages SpaceX's growing constellation of low-Earth orbit satellites, is currently rolling out in Canada and Japan, with potential for broader global adoption in the near future.
How Starlink's Direct to Cell Works with Apple Watches
Starlink's Direct to Cell technology is designed to provide cellular-like connectivity without the need for traditional ground-based towers. By beaming signals directly from satellites to compatible devices, it ensures coverage in areas where conventional networks fall short, such as rural landscapes, oceans, or mountainous regions. Initially focused on smart phones, the service has now been extended to Apple's latest smartwatches.
Compatible models include the cellular versions of the Apple Watch Ultra 3, Series 11, and SE 3. These devices can connect to Starlink satellites to handle basic communication tasks. Users do not need any additional hardware modifications—the watches use their built-in Long-Term Evolution capabilities to interface with the satellite network.
In practice, when an Apple Watch detects no terrestrial cellular signal, it can automatically switch to satellite mode. The process involves pointing the watch toward a clear view of the sky, similar to how Apple's own Emergency Satellite Service functions on iPhones. However, Starlink's implementation is powered by SpaceX's advanced satellite infrastructure, which includes over six thousand satellites in orbit as of late 2025, with hundreds equipped for Direct to Cell operations.
Rollout Details: Availability in Canada and Japan
The service launched in Canada through a partnership with Rogers Communications, where it is offered as a free test version to all eligible users. This means Apple Watch owners on Rogers' network can test the feature without extra costs, providing valuable feedback to refine the technology.
In Japan, the rollout is tied to Au (KDDI), one of the country's major carriers, via their Starlink Direct service. Users must subscribe to this plan to access satellite connectivity on their watches. The integration highlights Starlink's strategy of collaborating with local telecommunications providers to comply with regional regulations and expand reach.
While the feature is limited to these two countries for now, SpaceX has hinted at broader availability. In the United States, T-Mobile—Starlink's primary partner—could introduce similar support soon, potentially bringing the capability to American users. Other regions, including Europe and Asia-Pacific, may follow as more satellites are deployed and partnerships are forged.
Supported Features and Limitations
At launch, the primary function enabled by Starlink on Apple Watches is text messaging through the native Messages application. This allows users to send and receive Short Message Service or iMessages even in complete cellular dead zones, which is particularly useful for hikers, sailors, or anyone venturing off the grid.
Some reports suggest the service may also support emergency messaging, enabling users to contact authorities in critical situations. However, full internet browsing, voice calls, or data-intensive applications are not yet supported on watches via this method. SpaceX emphasizes that the technology is optimized for low-bandwidth tasks to ensure reliability and efficiency.
Limitations include the need for a clear line of sight to the sky—obstructions like dense forests or buildings can hinder connectivity. Connection times may also be slower than traditional cellular, with messages taking up to a minute to send or receive. Battery life could be impacted during extended satellite use, though Apple has optimized its watches for such scenarios.
Broader Implications for Satellite Connectivity
This integration represents a convergence of wearable technology and space-based infrastructure, potentially reducing reliance on ground networks. For Apple, it complements their existing satellite features on iPhones, such as Emergency Satellite Service and roadside assistance, which currently rely on Globalstar's satellites. Rumors swirl about deeper collaborations between Apple and SpaceX, including premium paid tiers for advanced satellite services or even acquisitions that could merge technologies.
On a larger scale, Starlink's Direct to Cell aims to bridge the digital divide, connecting billions in underserved areas. With partnerships like T-Mobile in the United States and Boost Mobile expanding the service, SpaceX is positioning itself as a leader in hybrid satellite-cellular networks.
Looking Ahead
As SpaceX continues to launch more Direct to Cell-capable satellites—targeting full global coverage by the year 2026—the inclusion of devices like Apple Watches signals a future where connectivity is truly ubiquitous. Users in Canada and Japan can already experience this, and with Apple's ongoing satellite innovations, we may soon see even more features, such as image sharing or third-party application integration.
