Are there any known issues with the Apple Watch Ultra 2's GPS in areas with no cell service

GPS Functionality Without Cell Service

1. Independent GPS Operation: The Apple Watch Ultra 2 can track GPS routes and distances without needing a paired iPhone or cellular connection. Users have confirmed that the watch can successfully track runs and other activities while being completely disconnected from their phones and cellular networks[5].

2. Cached Satellite Data: The watch can cache satellite orbit predictions, allowing it to quickly acquire GPS signals even in remote areas. This feature is particularly beneficial when venturing into the wilderness where cellular service is unavailable[2].

Known Issues

1. Accuracy Concerns: Some users have reported issues with GPS accuracy in challenging environments, such as dense forests or urban canyons. While the dual-frequency GPS is intended to enhance accuracy, there are instances where users have experienced erratic location readings or discrepancies in distance tracking, especially when compared to dedicated GPS devices[6][3].

2. Erratic Readings: There are reports of the Ultra 2 displaying inconsistent GPS readings, such as jumping around in location data or showing inaccurate distances, particularly under difficult conditions. This has led some users to question the overall reliability of the GPS system in certain scenarios[6].

3. User Experiences: Feedback from users indicates that while the GPS generally works well, it may not always meet the accuracy standards set by specialized GPS devices. Some users have expressed frustration with the watch's performance in remote areas, noting that it can sometimes be less reliable than expected[6][3].

Conclusion

In summary, while the Apple Watch Ultra 2 can track GPS accurately without a phone connection, there are known issues related to accuracy and reliability in certain environments. Users should be aware of these potential limitations, especially when relying on the watch for navigation in remote or challenging conditions.
