The Cosmo JrTrack 5 SE is a standalone kids smartwatch from Cosmo, priced at $129.99 for the device plus a required Cosmo Mobile membership. Built for children ages 6–12, it pairs real calling and texting with precision GPS tracking and strict parental controls, all without internet browsing or social media. If you want to give your child a first phone that keeps them connected while keeping you in control, this is one of the more complete options available.
What It Is
The JrTrack 5 SE is a cellular kids smartwatch, not a companion device that leans on your phone. It ships with its own eSIM and phone number, so your child can call and message approved contacts over Cosmo’s 4G LTE network without carrying a smartphone.
The “SE” distinguishes it with the same proven JrTrack 5 hardware now running Cosmo’s rebuilt parent app, which adds Routines and the new School-Fi focus system. It comes with a charging clip, two screen covers, both silicone and Velcro band options, and a wall adapter. What sets it apart is the combination of a locked-down, parent-approved ecosystem with real messaging and a camera, something many competing watches skip.
Key Features
HaloGPS and Active Tracking give you precise, real-time location. Active Tracking refreshes your child’s location every 10 to 15 seconds, and you can set SafeZones around home, school, or practice to get automatic alerts when they arrive or leave.
School-Fi is the standout here. Search your school, set the time and location, and the watch automatically switches into a distraction-free mode during class hours while your child is on campus. Paired with the Explorer Clip design, it also doubles as a backpack clip for “away for the day” school policies.
Real Texting and Calling cover true SMS and MMS with parent-approved contacts, including text, picture, video, and audio messaging, group chats, and voice-to-text. The watch is firewalled against unknown numbers, so spam and strangers can’t get through.
SafeCORE Safety Tools bundle SafeZone alerts, optional 911 calling you can toggle on or off, an SOS mode triggered by double-tapping the power button, and the trusted contact list. Together they give you a four-part safety net on your child’s wrist.
Parental Controls run through the redesigned Cosmo app, where you approve contacts, review message transcripts in the Parent Insights Dashboard, set daily app time limits, and adjust focus settings. You decide how much the watch can do and when.
Durable, Everyday Hardware includes an IP68 rating against dust and water up to 1.5 meters, all-day battery life, a photo and video camera, and changeable wrist bands. Cosmo backs it with a 3-year warranty and a 30-day money-back guarantee.
Optional extras round things out, including kid-safe apps and music through the App Station with Spotify, Spotify Kids, and iHeartRadio, plus games, learning tools, and wellness apps like Calm and GoNoodle.
Who It’s For
This watch is aimed squarely at parents of kids ages 6–12 who want connection without handing over a full smartphone. If your child is walking to school, heading to sports practice, or spending the night at a friend’s house, the GPS tracking and SafeZone alerts are built for exactly those moments.
It’s also a strong fit for families navigating school phone bans, since School-Fi and the Explorer Clip were designed with classroom policies in mind. Because it grows with your child, you can start with the basics and unlock more features as they’re ready, making it a sensible choice for a first device.
Keep in mind the device requires a Cosmo Mobile membership to activate. Plans start at $9.99/mo on the 2-year prepaid option ($239.76 upfront), with a popular 1-year plan at $12.99/mo ($155.88), a 6-month plan at $14.99/mo ($89.94), and a no-commitment pay-as-you-go plan at $19.99/mo. A one-time $14.99 activation fee applies to new lines.
If you’re weighing a first phone for your child, the Cosmo JrTrack 5 SE packs real communication, serious location tracking, and genuine parental control into one durable package for $129.99.
