How do I activate or refill my U.S. SIM card?
Your LAGENIO U.S. kids smartwatch comes with a pre-installed Nio SIM card, with service provided by SpeedTalk.
Why can't I turn off the watch?
The "Prevent Shutdown" feature might be enabled in the app. You can disable it by going to [More] - [Watch Settings] in the app and turning off the "Prevent Shutdown" switch.
Why won't the watch charge?
Possible reasons include:
- The battery might be completely drained if the watch hasn't been used for a long time. Charge it for at least 15 minutes before checking.
- Ensure you are using the standard charging adapter.
- The charging contacts on the watch and the magnetic charging cable might be dirty. Clean them regularly.
- The magnetic charging cable might not be properly attached. Align the watch's charging contacts with the cable's metal contacts until they are fully attached. The charging animation should appear on the screen.
- Check the power source: ensure the power strip is on, the USB port is functioning, or the power adapter is not faulty. 6.If none of these solutions work, the watch might be faulty. Please contact customer service.
How long does it take to fully charge the watch?
It typically takes 2.5-3 hours to fully charge the watch.
How can I improve the watch's battery life?
Ensure the watch firmware is up to date. Then:
Enable "Scheduled On/Off" in the app's [More] section.
Set the location mode to "Power Saving Mode" in the app's [Location] section by clicking the top right "..." and selecting [Location Mode Settings].
Enable "Reserve Battery" in the app's [More] section.
How do I set the correct date and time on the watch?
The watch will automatically sync the time from the server once a SIM card is inserted. Alternatively, after binding the watch to the app, you can manually set the time zone in the app settings.
Why doesn't the watch ring for incoming calls? Why is there no sound?
Check the volume settings on the watch under [More] - [Settings] - [Volume Settings] to ensure the volume is not too low and that the silent mode is not enabled.
If there is no sound during calls, the watch might be faulty.
Please contact customer service.
Can the watch be worn while swimming, washing hands, or bathing?
The watch is water-resistant for daily activities like washing hands but is not suitable for swimming, diving, or activities involving high-speed water flow or submersion below diving depths.
Why does the watch display a high-temperature warning?
The watch will display a high-temperature warning when the NTC (Negative Temperature Coefficient) sensor detects that the battery temperature exceeds the set threshold.
NTC detection standards:
Charging state: 50°C triggers a high-temperature warning and stops charging. Charging resumes at 45°C, and the warning closes automatically. At 55°C, the device will shut down.
Non-charging state: 45°C triggers a high-temperature warning, and the warning closes at ≤42°C.
Why does the watch sometimes get hot?
Reasons for heating include:
The 4G network supports fast data transmission, which generates more heat.
The watch uses an Android-based system that requires powerful hardware, leading to heat generation.
The small size of the watch limits heat dissipation, causing noticeable warmth.
Video chatting increases the likelihood of heating.
4G-VoLTE high-definition calls consume more power and generate more heat compared to traditional voice calls.
Fast charging generates heat, which is common for all electronic devices.
What are the special modes (High-Temperature Warning Mode, Reserve Battery Mode)?
High-Temperature Warning Mode:
During video chats or charging, if the watch gets too hot, it will display "The watch is too hot, please take a break." Normal use can resume once the temperature drops.
Reserve Battery Mode:
Enable this mode in the app's [More] - [Reserve Battery] section. The watch will enter power-saving mode when the battery is low, retaining only call functions. The main screen will display "Reserve Battery Mode Enabled."
How many contacts can I add to the watch?
You can add up to 15 contacts, with a maximum of 3 emergency contacts.
How do I bind the watch to the app?
Insert a valid SIM card into the watch.
Once the watch connects to the server, go to the [Bind] menu on the watch, and a 10-digit binding code will appear.
Open the app and scan the QR code or enter the binding code manually.
Ensure the app's region matches the watch's default server IP.
Why can't I receive the verification code when registering with an email?
Check if the email address is correct.
Ensure your email settings do not block unknown senders and check your spam folder.
Why can't I log in to the app after registration?
Ensure the account details are entered correctly, paying attention to case sensitivity.
Accounts registered in different regions are not interchangeable.
For example, if you registered in the Asia region, you cannot log in with the same account in the Europe region.
How can I add other family members to manage the watch?
The admin can display a QR code in the app for other family members to scan and request access. The admin must approve the request before other members can use the app.
Why am I not receiving notifications?
Ensure you have granted all necessary permissions to the app, such as notifications, background running, and autostart.
Regularly open the app to prevent it from being killed by the phone system.
Why can't I record or hear audio in voice chat?
Ensure the app has microphone permissions enabled in your phone's settings. If the issue persists, reinstall the app and grant microphone permissions when prompted.
Why can't I see my child's chat history?
To protect children's privacy, chat histories between children are not accessible to parents. Third-party interfaces do not support viewing other people's chat records.
Why am I not receiving voice chat or video call notifications?
Ensure you have granted all necessary permissions to the app, such as notifications, background running, and autostart. Regularly open the app to prevent it from being killed by the phone system.
How long can video calls last?
Video calls are limited to 5 minutes to prevent the watch from overheating.
Why does the watch show as offline when trying to locate it?
Possible reasons include:
The watch is out of credit or turned off.
The watch's network is not connected. Check the connection status on the watch's main screen. If disconnected, restart the watch or connect to WiFi.
The watch is in a weak signal area (e.g., elevator, basement, subway, high-speed train).
Verify by calling the watch.
The watch is in reserve battery mode, with the network disabled.
Why is the location sometimes inaccurate?
The watch uses GPS, WiFi, and cellular towers for positioning. Accuracy varies based on the environment:
GPS: ~10 meters
WiFi: ~450 meters
LBS: ~550 meters (can be larger in practice)
The watch cannot be located when turned off or without a network connection
Can the watch be located during school hours when disabled?
Yes, location tracking remains active even when the watch is in school mode.
