- SIM card not detected: Verify the Nano SIM card is correctly inserted and activated with a 4G plan. Restart the watch.
- Inaccurate location tracking: Ensure the watch has a clear view of the sky for GPS. Indoor positioning relies on Wi-Fi and LBS, which may be less precise. Check app settings for location services.

- App connectivity issues: Ensure your smartphone has a stable internet connection. Restart both the watch and the app.

- Monitor Health Features: The heart rate and blood oxygen monitoring features are for general wellness and fitness purposes. They are not medical devices and should not be used for diagnostic or treatment purposes.
- App Permissions: Ensure the 'Setracker' app has all necessary permissions on your smartphone (location, contacts, notifications) for optimal performance.
