Safe Technology for Kids – A Smart Alternative to a Smartphone
The STELIO Junior 4G smartwatch is a modern and well-designed solution created specifically for the youngest users.Instead of unrestricted access to the internet and social media, it offers carefully selected features that allow children to stay in touch with their families—in a safe, transparent, and age-appropriate way.It’s the perfect alternative to a smartphone, combining security with the convenience of everyday communication—without the risk of digital overload or online threats.
STELIO Focuses on Innovation – Unisoc W117 in Smartwatches for Kids
STELIO is introducing the Unisoc W117 chipset to the Polish market; this is the first time it has been used in children's smartwatches.Previously used in watches for adults by global brands, the W117 has been paired with a lightweight, energy-efficient RTOS, ideal for compact devices.The new chip significantly outperforms previous technological solutions used in this class of smartwatches and adds new features to them.
SMS Support and an Additional SOS Feature—Fast and Secure Communication
Thanks to the W117 chipset, the watch supports SMS messages—both receiving and replying using five predefined messages.With just one click, a child can send a message such as “I’m here” or “I’ll call you later” without having to type anything on the screen.In addition, the watch includes a special SOS message: “I need help.”!"which allows you to immediately notify a caregiver in an emergency and increases the caregiver's safety".
UCVS Technology: Smart Energy Management—Longer Run Time, Less Charging
The smartwatch with the Unisoc W117 chipset offers longer battery life thanks to UCVS (Ultra-low-power Comprehensive Voltage Scaling) technology—an intelligent power management system developed by Unisoc.UCVS automatically puts the watch into sleep mode or turns off data transmission when it is not needed, which significantly reduces power consumption.This is a next-generation solution, ideal for children's smartwatches.
Faster connectivity and a stable system—greater convenience in everyday use
RTOS smartwatches for children on the Polish market are based on the slower LTE Cat 1 standard.The Unisoc W117 chipset introduces support for LTE Cat 4+1, offering significantly faster data transfer speeds and smoother performance for key features such as video calls and data exchange with the Stelio Tracker app.It is the first in this category to support Wi-Fi connectivity, improving the stability of the internet connection where LTE fails.What's more, users can update the system themselves—via Wi-Fi or a cellular network—without having to contact customer service.

A crisp, durable display – 1.75" IPS with Gorilla Glass protection
The STELIO Junior 4G features a clear 1.75" IPS screen with a resolution of 240 × 298 px, perfectly suited to the watch's interface.The display is protected by Corning Gorilla Glass, which is resistant to minor impacts and drops—a rarity in this price range.As a result, the smartwatch retains its aesthetic appeal and functionality even with heavy use by a child.
Location and Safety Zones – Peace of Mind for Parents, Freedom for Children
STELIO Junior 4G lets you track your child's location in real time using a combination of GPS, Wi-Fi, and LBS, providing a precise overview in the Stelio Tracker app.The safety zones feature allows you to designate locations such as home or school—when a child leaves one of these locations, the parent receives an automatic notification.This is a practical solution that enhances a child's safety without restricting their freedom.

Video, voice, and phone calls—stay connected anytime, anywhere
The STELIO Junior 4G allows you to make phone calls, including voice and video calls, thanks to its support for 4G LTE networks.This allows parents to get in touch with their child at any time—to hear or see them—whether they're at home, at school, or out for a walk.Communication is reliable, fast, and secure, proving effective both in everyday interactions and in situations where a quick response is essential.
Camera and Video – Simple Photos and Video Calls for Everyday Use

Voice Messages and Emojis – A Convenient, Kid-Friendly Way to Communicate

Class Mode and Contact Protection – Peace of Mind for Parents, Focus for Children
The STELIO Junior 4G offers a practical "class mode" that automatically turns off most of the watch's functions during selected hours—such as during school hours—helping your child focus on their studies.In addition, the feature that blocks calls from unknown numbers ensures that only people saved in the phone book can contact the watch, providing your child with safe and controlled communication.
700 mA battery + UCVS technology = the most efficient RTOS smartwatch for kids
As mentioned earlier, UCVS technology intelligently manages the smartwatch's power consumption, significantly extending its battery life.In addition, the device is equipped with a 700 mAh battery, a power-saving mode that automatically locks the smartwatch when the battery is low, and an auto-on/off feature that adjusts the watch’s operation to the child’s daily routine.It's a complete solution that ensures long battery life, convenience, and peace of mind for both the child and the parent.

An Extra Layer of Protection – Advanced Tools for Parents
The STELIO Junior 4G is equipped with a range of tools that help parents keep an eye on their child's safety.Voice monitoring lets you discreetly check your surroundings, and the remote photo feature lets you take a photo with the watch's camera directly from the app.Parents also have access to call history and text messages, and thanks to the feature that blocks calls from unknown numbers, only people saved in the phone's contact list can contact the child.This ensures transparent and secure communication.
Keep Track of Your Child's Activity Every Day
