How to Fix Error Code 8

  1. Step Outside and Check Your Environment

  2. Restart Your Apple Watch

  3. Enable Location Services on Your iPhone

  4. Check Apple Watch Location Permissions

  5. Reset Location & Privacy Settings on iPhone

    This reset will clear all saved location permissions for every app on your iPhone. You will need to grant location access again to apps that request it.

  6. Update watchOS and iOS to the Latest Version

    Ensure your Apple Watch has at least 50% battery before starting a software update to avoid interruption.

  7. Unpair and Re-Pair Your Apple Watch

When to Call a Professional

If you have completed all software troubleshooting steps — including resetting location settings, updating both devices, and unpairing/re-pairing the watch — and GPS still does not function during outdoor workouts, the GPS antenna or GPS module inside the Apple Watch may be physically damaged or defective. In this case, contact Apple Support or visit an Apple Store for hardware diagnostics. If your Apple Watch is within its one-year limited warranty or covered by AppleCare+, repair or replacement may be covered at no cost to you.

Frequently Asked Questions

Why does my Apple Watch say GPS not available during a workout?
This usually means the watch cannot lock onto satellite signals. Common causes include being indoors or near tall buildings, having Location Services turned off on your iPhone, outdated watchOS software, or a temporary software glitch. Start by moving to an open outdoor area, then follow the troubleshooting steps above if the problem persists.
Does Apple Watch GPS work without iPhone nearby?
Yes — Apple Watch Series 2 and later models have built-in GPS and can track workouts without your iPhone nearby. However, for the fastest GPS lock, carry your iPhone with you for the first few workouts after a reset, as the iPhone provides assisted GPS (A-GPS) satellite data that speeds up acquisition.
How long should it take for Apple Watch to find GPS signal?
Under normal conditions outdoors, Apple Watch should acquire a GPS signal within 30–60 seconds. If it is taking longer than 2–3 minutes in an open area, there is likely a software or hardware problem that needs troubleshooting.
Will unpairing my Apple Watch delete my workout history?
No — when you unpair your Apple Watch using the iPhone Watch app, your iPhone automatically creates a full backup of your watch data, including workouts and health data synced to Apple Health. When you re-pair the watch, you can restore from that backup and retain your history.
Can a software update fix Apple Watch GPS problems?
Yes, software updates frequently include GPS performance improvements and bug fixes. Apple has released several watchOS updates specifically addressing GPS signal acquisition issues. Always keep both your Apple Watch and iPhone updated to the latest software versions to benefit from these fixes.
