The K11 works with a compatible physical 4G Nano SIM that supports both voice calling and mobile data. eSIM is not supported, and data-only SIM cards are not recommended.

For the most reliable experience, we recommend using a SIM issued directly by the mobile network operator itself, rather than an MVNO using the same network. Some MVNO SIMs may also work, but compatibility can vary.

The K11 is rated for 2ATM water resistance and is suitable for normal swimming in a pool and other shallow freshwater activities.

2ATM means the watch is tested to withstand water pressure equivalent to approximately 20 meters of static water depth under test conditions. It does not mean the watch is suitable for all activities at a depth of 20 meters.

Water resistance is not permanent and can decrease over time or after drops, impacts, chemical exposure or damage to the watch’s water-resistant structure.

To help maintain water resistance, avoid the following:

• Showers with soap or body wash, diving, hot springs, saunas, seawater activities, high-pressure or fast-flowing water, and jumping or diving into water from a height.
• Sudden temperature changes of more than 5°C, such as heating the watch with hot air.
• Operating the watch or removing the SIM card while the watch is wet.
• Leaving the watch in clothing that may be put into a washing machine, or allowing the watch to be dropped or hit.
• Continuous immersion in water for more than 2 hours.
• Contact with alcohol, solvents, hand sanitizer, soap, detergents, perfume, lotion, sunscreen, oils, hair dye, bubble solution or other chemicals.

In simple terms: K11 is designed for normal swimming and shallow-water activities, but avoid diving, hot water, seawater, high-pressure water and prolonged immersion.

After handwashing, water play or swimming, remove the watch and dry it with a clean, soft cloth.

Allow water in the speaker and microphone openings to drain or air-dry naturally. Do not use heat, compressed air or insert objects into the openings, as this may damage the water-resistant structure.

If the watch comes into contact with seawater or another liquid besides fresh water, gently rinse it with fresh water and dry it thoroughly.

After exercise or heavy sweating, clean and dry the watch, strap and skin. The touchscreen and some functions may not operate normally while the watch is underwater or wet.

K11 combines a built-in 5MP HD camera, AI vision recognition and voice interaction to help children explore and learn about the world around them.

Kids can photograph something they do not recognize — such as an animal, plant, landmark or everyday object — and use AI vision recognition to learn more about it.

They can also ask questions by voice and receive spoken answers and follow-up explanations, making everyday discovery more natural without typing or using an open web browser.

For example, if a child sees an unfamiliar animal outdoors, they can take a photo, identify it with NIO AI and continue asking questions by voice.

Yes. K11 supports 100+ wide selection of watch faces, including dynamic watch faces, giving children more ways to match the watch to their mood and style.

Dynamic designs, smooth animations and responsive touch controls make everyday interactions feel more playful and personal — helping K11 become a watch kids actually enjoy wearing.

K11 combines 16GB of built-in storage with 2GB of RAM, providing plenty of room for photos, videos, learning content and watch faces while keeping everyday use smooth and responsive.

The watch can store about 1,000+ photos, giving kids plenty of space to capture family moments, outdoor adventures and everyday discoveries without constantly worrying about storage.

Note: Actual photo capacity varies depending on image size, file format, system storage and other content saved on the watch.

Parents manage contacts through the LAGENIO App. The K11 supports up to 50 contacts, giving families more flexibility to add parents, grandparents and other trusted people.

Parent-managed contacts help keep communication centered around family and trusted connections rather than unknown callers.

The K11 also includes an SOS function so children can quickly reach designated emergency contacts when they need help.

No. The K11 does not support third-party messaging or social media apps such as WhatsApp, and it does not provide an open app store or unrestricted web browsing.

The K11 does include Nio AI features and a few simple built-in puzzle games, giving children useful features and a little room for fun without the endless apps, social feeds and online distractions of a regular smartphone.

Class Mode helps reduce distractions during scheduled school hours. The K11 supports up to 10 Class Mode schedules, giving parents more flexibility to match different lessons and school routines.

When Class Mode is active, distracting watch functions are restricted so children can stay focused during class, while important functions such as location tracking remain available to parents.

Normal watch functions return automatically when the scheduled Class Mode period ends.

The K11 supports 4G Voice Call, Video Call and NIO Call, giving families several ways to stay connected.

4G Voice Call uses a compatible Nano SIM and the carrier’s voice service. NIO Call works over Wi-Fi or 4G mobile data, while Video Call supports face-to-face family check-ins.

K11 also supports Micro Chat and picture sharing. Micro Chat messages can contain up to 128 English characters, so children can send short text messages and share pictures with family.

The K11 supports up to 8 alarms, giving families more flexibility to create reminders for waking up, school routines, activities and other parts of the day.

The K11 has an 800mAh battery designed to support everyday routines such as school, after-school activities, family check-ins, calls and location updates.

Actual battery life varies with use. GPS update frequency, video calls, screen brightness, mobile signal strength, AI use and other connected features can all affect how long a charge lasts.

For the most reliable day-to-day experience, we recommend making charging part of your child’s evening routine, similar to charging a smartphone, so the K11 is ready with a full battery for the next day.

Because usage patterns and network conditions differ, actual battery life can vary from one family to another.

Lagenio prioritizes data security and privacy. Access to manage the K11 through the LAGENIO App is parent-controlled, and additional family members must request access and be approved by the administrator.

We use encrypted servers, GDPR-compliant standards, and no third-party data sharing, ensuring your child's information remains protected.

LAGENIO offers a 30-day return period for eligible purchases. If the K11 isn’t right for your family, you can request a return or exchange within 30 days of receiving your order, provided it meets the conditions of our Return Policy.

Please contact LAGENIO Support before sending the watch back so we can guide you through the return process.
