# Apple Watch Ultra 3: Advancing into Satellite Connectivity and Enhanced Functions
When the Apple Watch was launched in 2015, it relied on the iPhone for data transfer. Fast forward to the present, the Apple Watch Ultra 3 has unveiled revolutionary features, including satellite connectivity, enabling it to communicate in remote locations without cellular service.
## Satellite Connectivity
The Apple Watch Ultra 3 is the inaugural model to feature satellite connectivity, a capability that was first introduced with the iPhone 14. This function empowers users to reach emergency services without a cellular link. The satellite service is offered at no additional cost for two years post-purchase, although Apple has not released any information regarding future fees for this service.
### Testing Satellite Features
Assessing satellite connectivity consists of four primary elements:
1. Establishing a link to a satellite.
2. Reaching emergency services through SOS.
3. Sharing location with a contact.
4. Sending messages to a contact.
While a valid cellular plan is needed for messaging and location sharing, Emergency SOS via Satellite functions separately from cellular service. Users can conduct a connection demonstration to get acquainted with the satellite features without being in a crisis.
The Apple Watch Ultra 3 can recommend initiating a satellite connection when outside cellular range, with the connection procedure necessitating a clear view of the sky. The watch will guide users to the closest satellite, although barriers like trees may impede connectivity.
## 5G Connectivity
Alongside satellite functions, the Apple Watch Ultra 3 now accommodates 5G cellular connectivity, marking a notable enhancement as 5G networks grow. This newly designed modem prioritizes power efficiency while providing enhanced internet speeds. The dual antenna system adjusts to signal strength, optimizing connectivity according to the surroundings.
## Display Enhancements
The Ultra 3 showcases a 24% decrease in bezel dimensions, reclaiming its status as having the largest display in an Apple Watch. This upgrade, in conjunction with innovative display technology that allows for second updates in always-on mode, significantly enhances the user experience.
## Battery Life Improvements
The Apple Watch Ultra 3 features the longest battery lifespan of any Apple Watch thus far, lasting up to 42 hours under typical usage. This enhancement is due to a 6% boost in battery capacity, a more efficient display, and the newest 5G modem. The fast charging capability allows for swift top-ups, making it convenient for daily functionality.
## watchOS 26 Features
The Ultra 3 operates on watchOS 26, introducing novel health features such as hypertension alerts and a sleep scoring system. These improvements grant users more profound insights into their health metrics, rendering the watch a more thorough health monitoring device.
## Conclusion
The Apple Watch Ultra 3 signifies a major step forward in wearable technology, incorporating satellite connectivity, 5G compatibility, alongside improved display and battery functions. Priced at $799, it provides significant value for those in search of a high-performance smartwatch. Whether upgrading from an earlier version or acquiring a smartwatch for the first time, the Ultra 3 presents a comprehensive range of features that enhance connectivity and health tracking.
The Apple Watch Series 11 and SE 3 also enter the lineup, delivering impressive enhancements and value for users at various price tiers, ensuring that Apple continues to address a broad spectrum of smartwatch enthusiasts.
