Apple is set to revolutionize its smartwatch lineup with the upcoming Apple Watch Ultra 3, expected to launch in September 2025. According to Bloomberg’s Mark Gurman, the latest Ultra model will introduce satellite connectivity and a 5G cellular modem, significantly enhancing off-grid communication and overall user experience.
For years, Apple has dominated the smartwatch market, but competitors like Garmin, Suunto, and Coros have carved out a niche for extreme sports and adventure enthusiasts. With this latest innovation, Apple is not just keeping up—it’s setting a new benchmark for high-performance wearables.

Satellite Messaging Comes to Apple Watch: A Breakthrough in Communication
Apple first introduced satellite texting with the iPhone 14, allowing users to send emergency messages without cellular or Wi-Fi connectivity. The feature has since evolved, expanding in iOS 18 to support messages to any contact, not just emergency responders. Until now, however, this technology had not been integrated into the Apple Watch lineup.
Why Satellite Connectivity Matters
For adventurers, outdoor enthusiasts, and professionals who work in remote locations, connectivity is often a challenge. Satellite messaging in the Apple Watch Ultra 3 will enable users to:
✔ Send texts from anywhere – Whether trekking in the Himalayas, diving in the Pacific, or exploring the Amazon rainforest, users can stay connected. ✔ Enhance safety – Emergencies can arise at any time. With satellite connectivity, help is just a message away, even in cellular dead zones. ✔ Compete with Garmin and Others – Garmin has long been a leader in satellite-equipped gear. Apple’s move ensures the Ultra 3 is a formidable contender in this space.
This technology ensures that Apple Watch users are no longer dependent on traditional networks, providing a true sense of security and reliability.
Upgrading to 5G: A New Era for Apple Watch Connectivity
Beyond satellite messaging, the Apple Watch Ultra 3 will be Apple’s first smartwatch to support 5G connectivity. While iPhones adopted 5G years ago, Apple Watches have remained on 4G LTE—until now.
Apple’s decision to switch from Intel to MediaTek modems is a significant move. MediaTek’s 5G RedCap technology is specifically designed for wearables, offering low-power, mid-speed 5G that balances efficiency and speed. This means:
✔ Faster data speeds – Quicker app loading, smoother streaming, and improved call quality. ✔ Better battery performance – Unlike power-hungry 5G chips used in smartphones, RedCap ensures long-lasting battery life. ✔ More efficient connectivity – Seamless transitions between Wi-Fi, cellular, and satellite for an uninterrupted experience.
Apple’s shift to 5G in wearables is a significant step toward a more connected, high-performance smartwatch experience.
What to Expect from the Apple Watch Ultra 3
Apple’s Ultra series has always been designed for athletes, divers, and adventure seekers. The Ultra 3 is expected to continue this trend with several enhancements beyond just connectivity.
1. Rugged Design for Extreme Conditions
The Apple Watch Ultra series is already known for its titanium case, sapphire crystal display, and water resistance up to 100m. The Ultra 3 will likely maintain or improve upon these specs, ensuring durability in harsh environments.
2. Advanced Health and Fitness Tracking
Apple Watch has long been a leader in health tracking, and the Ultra 3 is expected to push the boundaries further. Potential features include:
- Blood pressure monitoring
- Improved sleep tracking
- Better altitude acclimation features for hikers and mountaineers
- Enhanced dive metrics for underwater explorers
3. Extended Battery Life
Battery life is a crucial factor for adventurers. With power-efficient 5G RedCap modems and Apple’s ongoing battery optimizations, the Ultra 3 could see longer battery life, possibly exceeding 36 hours on a single charge.
4. Enhanced Navigation & GPS Features
With Apple’s Precision Finding and Dual-frequency GPS, the Ultra 3 may introduce even better navigation tools for hikers, runners, and sailors. This could include:
- Improved topographic mapping
- Enhanced route tracking with real-time elevation changes
- Integration with satellite imagery
Apple vs. Garmin: Can Ultra 3 Compete?
Apple’s biggest competition in the adventure smartwatch segment remains Garmin, which has dominated the rugged GPS smartwatch market for years.
