Problem	Possible Cause	Solution
Watch won’t turn on	Battery is discharged or faulty	Fully charge the watch, wait a few minutes, and try turning it on. If the watch still does not turn on, contact the warranty service center.
No network / cannot make calls	SIM card not inserted, no mobile data plan, weak signal	Check the SIM card and data plan; make sure there is 4G coverage in your area.
Inaccurate location information	GPS signal blocked, watch indoors, weak signal, or mobile data plan expired	Ensure the mobile data plan is active and not depleted. Make sure the watch battery is not empty or in power-saving mode. If the child is indoors without Wi-Fi, the location may be less accurate, as less precise methods are used.
Geo-Fence alerts not working	Geo-Fence zones not configured correctly in the app, permissions disabled	Check Geo-Fence zone settings in the app and ensure the app has permission to send notifications.
Chat / voice messages not working	Microphone or storage permissions not enabled	Enable microphone and storage permissions on your phone. If needed, reinstall the app and grant all requested permissions during installation. Also, enable pop-up permissions.
Short battery life	Frequent location updates, active additional functions (AI function Nio AI, video calls, camera, etc.)	Adjust the automatic location update interval and agree with the child to limit the use of additional watch functions when outside the home.
Watch shows as “offline” in the app	Watch turned off or no network	Check that the watch is not discharged. If the watch was turned off via the app, it can only be turned on manually. If the watch is on, check that the SIM is correctly inserted, there is a network signal, and mobile data is active. Without mobile data or with an expired plan, the watch cannot connect to the server, and the app will show it as offline.
