Why parents choose the KN25
Between the school gates, football practice and walking home with friends, children aged 5–12 start building a world of their own. KN25 keeps you part of it.
They can call or video call you whenever they need to. You can see where they are in the SeTracker2 app and set safe zones that let you know if they leave. And the SOS button is always there for the moments that matter.
More freedom for them. More reassurance for you.

Why parents choose KidNavi
A KidNavi watch gives children the freedom to explore, with a simple way to stay in touch.
Calls, video calls and location with family come first, rather than the open web, social media and app stores of a typical smartphone.
See where they are in the SeTracker2 app and get an alert if they leave a safe zone. GPS accuracy depends on signal and can be lower indoors.
A step towards walking to school, staying at a friend's or going to clubs, with a simple way to stay in touch.
A small wrist screen built around calls, messages and safety, so there's less temptation to scroll for hours.
No device can remove every risk. A KidNavi watch is one helpful tool alongside the conversations and boundaries you already have as a family.

SIM & setup
Calls, GPS location and the app all run over mobile data, so the watch needs a nano-SIM with a data and calling plan.
A SIM isn't included, so you can pick a pay-monthly or pay-as-you-go plan that suits your family and budget.
Use a 4G nano-SIM from a UK network. If you're unsure about yours, message us on WhatsApp before you order.
Make sure the SIM is activated, has data and calling, and doesn't ask for a PIN. Test it in a phone if you're not sure.
Charge the watch fully with the magnetic charger in the box before you start.
With the watch switched off, insert an activated nano-SIM with data, then switch it back on.
On your phone, download the SeTracker2 app, scan the watch's code and follow the quick-start guide to add contacts and safe zones.
