TickTalk 5 - Best Premium Features
Check current price on Amazon →
The TickTalk 5 is the feature rich pick for kids smartwatches. 1.4 inch touchscreen, 5 megapixel front camera for video calls, voice calls and text messages, GPS plus WiFi location, 4G LTE works on AT&T and T Mobile networks (unlocked), 700 mAh battery, curated kids app store with parent approval, and step counter.
Real use: setup requires buying a separate SIM card (Red Pocket Mobile, Speedtalk, or similar offer plans starting at $10 per month). The watch handles video calls, voice calls, and group chats with approved contacts. The curated app store offers vetted educational and game apps with parent approval per app. Battery covers a full school day plus evening with active use.
Trade off: BYOSIM setup is more work than carrier branded watches. Price runs $200 to $250 plus monthly service. Some curated apps are paid. The TickTalk parent app interface, while feature rich, has a learning curve.
Best for: families willing to handle BYOSIM, kids who use video calls and limited apps, ages 6 to 11.
Verizon GizmoWatch 3 - Best Verizon Families
Check current price on Amazon →
The Verizon GizmoWatch 3 is the easiest setup for Verizon customers. 1.3 inch touchscreen, 5 megapixel front camera, video and voice calls, GPS with safe zone alerts, step counter, and $10 per month line on a Verizon family plan.
Real use: setup through the Verizon My GizmoHub app takes 15 minutes. Verizon coverage is among the best in many US areas. Parents can call the watch directly from their Verizon phone like a regular phone number. Approved contacts (up to 20) can call and message the watch. Safe zones (home, school, grandparents) trigger parent alerts on entry and exit.
Trade off: Verizon only; no carrier flexibility. 500 mAh battery requires daily charging with active use. Smaller display than Cosmo and Apple Watch SE.
Best for: existing Verizon customers, areas with strong Verizon coverage, parents who want simple one bill setup.
T Mobile SyncUp Kids Watch - Best T Mobile Families
Check current price on Amazon →
The T Mobile SyncUp Kids Watch is the T Mobile equivalent. 1.4 inch touchscreen, 5 megapixel front camera, video and voice calls, GPS plus WiFi positioning, step counter, music storage for offline play, and $10 per month line on a T Mobile family plan.
Real use: setup through the SyncUp Kids app is straightforward. T Mobile band 71 (600 MHz) coverage means strong reach in rural areas. Music sync from the parent's iTunes or Google Play lets kids listen on the watch. School mode silences notifications during class hours. SOS button calls a designated emergency contact.
Trade off: T Mobile only. 500 mAh battery requires daily charging with active use. SOS button does not call 911 directly; it calls a designated emergency contact (parent) who then calls 911 if needed.
Best for: T Mobile family plan customers, kids who like offline music, ages 6 to 11.
Cosmo JrTrack 3 - Best Largest Screen
Check current price on Amazon →
The Cosmo JrTrack 3 is the larger display pick. 1.7 inch touchscreen (largest in the kids category), 5 megapixel front camera, video and voice calls, GPS, 850 mAh battery, comprehensive parent app, and dedicated Cosmo Connect cellular service starting at $15 per month.
Real use: the larger screen makes typing and video calls feel more present. Battery life is the best in this category; kids often go 2 days between charges. Cosmo Connect bundles cellular with the watch purchase for simpler billing. Parent app handles location, contacts, school mode, and SOS settings.
Trade off: Cosmo Connect service is the recommended path; BYOSIM is supported but requires more setup work. Watch is slightly larger and heavier than the Verizon GizmoWatch. App ecosystem is smaller than TickTalk.
Best for: kids who want a clearer screen, families wanting bundled service, longest battery life needs.
Xplora X6 Play - Best Step Rewards
Check current price on Amazon →
The Xplora X6 Play is the activity rewards pick. 1.52 inch touchscreen, 5 megapixel front camera, video and voice calls, GPS, 800 mAh battery, and the Xplora Goplay program that converts kids steps into virtual coins for store items or charity donations.
Real use: the step rewards system motivates movement. Coins from step counts buy small Xplora store items or contribute to charitable donations the kid chooses. Video calling and voice calling work as expected. The parent app handles contacts, location, and school hours.
Trade off: Goplay rewards are a marketing hook with modest actual rewards. Carrier setup requires BYOSIM. Some parents find the rewards system confusing or feel uncomfortable with the gamification.
Best for: active kids, parents who want activity motivation built in, ages 7 to 12.
Spacetalk Adventurer 2 - Best Waterproof
Check current price on Amazon →
The Spacetalk Adventurer 2 is the waterproof pick for active kids. 1.45 inch touchscreen, 5 megapixel front camera, video and voice calls, GPS, IP68 water resistance for swimming and rain, 4G LTE BYOSIM, 750 mAh battery, and swappable straps for color customization.
Real use: the IP68 rating handles pool, ocean, and rainy outdoor play. Video and voice calling work over LTE or WiFi. GPS accuracy outdoors is solid. The build holds up to rough handling better than non waterproof competitors. Swappable straps in different colors let kids personalize.
Trade off: video calls do not work while submerged in water. BYOSIM carrier setup required. The companion app is functional but lacks some of the TickTalk curated features.
Best for: swimmers, beach families, outdoor active kids, anyone who needs water resistance.
Apple Watch SE Family Setup - Best iPhone Families
Check current price on Amazon →
The Apple Watch SE in Family Setup mode is the upmarket pick for iPhone households. 1.78 inch Retina display, fall detection, GPS plus cellular, voice and video FaceTime, Apple's Schooltime mode for class hours, and a parent managed iCloud account that controls contacts and apps without an iPhone for the child.
Real use: Family Setup lets a parent's iPhone manage the child's Apple Watch without giving the child their own iPhone. The watch makes FaceTime calls, sends iMessages, and tracks location through Find My. Schooltime mode hides notifications and shows a simple watch face during designated hours.
Trade off: Apple Watch is significantly more expensive at $250 to $350 plus the $10 per month cellular plan. iPhone required for setup and management. Apple Watch is targeted at older kids (9 plus) who can manage the touchscreen interface; not designed for younger kids.
Best for: iPhone family households, ages 9 to 12, families with the budget for Apple ecosystem.
How to choose a 4G smartwatch for kids
Match the carrier to coverage. Verizon and T Mobile both offer dedicated kids watch plans at $10 to $15 per month. Verizon has broad national coverage. T Mobile is strong in rural areas via band 71. AT&T does not have a dedicated kids watch but supports unlocked models like TickTalk and Spacetalk. Check coverage at home, school, and activities first.
Pick a watch that fits the kid's age and habits. Ages 5 to 7 need simpler interfaces; TickTalk and GizmoWatch work well. Ages 8 to 11 can handle most watches including the Apple Watch SE. Pre teens 11 plus may want phones instead; the Apple Watch SE Family Setup is a delay tactic before phone purchase.
Confirm video calling needs. All seven watches support video calling. If video is daily, the TickTalk 5 produces the best image quality. If video is occasional, any 5 MP camera watch suffices. The Apple Watch SE uses FaceTime which is excellent for iPhone family video.
Budget realistically. Watch hardware is $150 to $350. Monthly service is $10 to $20 per watch. Annual service runs $120 to $240 in addition to hardware. Family plan add ons (Verizon, T Mobile, Apple) are usually cheaper than separate MVNO plans for BYOSIM watches.
Parental controls and safety
All seven watches use a paired parent app on iPhone or Android. The app controls the approved contact whitelist (only those numbers can call or message), school hours mode, location settings and geofence alerts, SOS button configuration, and any app installation (where applicable).
The SOS button typically calls a designated parent or guardian, not 911 directly. Confirm the SOS path in the parent app before relying on it. Teach the child to use SOS only for emergencies; misuse can dilute parental response time.
What is not on this list and why
Generic Amazon kids watches under $100 from unbranded sellers often use older 2G or 3G modems that no longer work on US networks (3G shutdown completed in 2022). They also have weak parental controls and inconsistent GPS accuracy.
Fitness trackers without cellular (Fitbit Ace, Garmin vivofit jr) are good for activity tracking but offer no parent contact or location tracking beyond Bluetooth range. They complement but do not replace a 4G smartwatch for safety needs.

For most families the TickTalk 5 is the right pick. For Verizon families the GizmoWatch 3. For T Mobile families the SyncUp Kids Watch. For largest screen the Cosmo JrTrack 3. For waterproof the Spacetalk Adventurer 2. For iPhone families the Apple Watch SE Family Setup. All seven do the core job: keep parents and kids connected with location, voice, and video without giving the kid a full phone.
Frequently asked questions
Why pick a 4G smartwatch instead of giving the kid a phone?+
A smartwatch gives parents direct contact and location tracking without the social media, web browsing, and screen time concerns of a phone. The kid cannot install random apps, browse YouTube, or message strangers; only approved contacts in the parent app can reach them. Schools that ban phones often allow watches. The watch stays on the wrist and rarely gets lost. For ages 5 to 10 a watch covers the safety and communication needs without exposing the child to the wider internet.
What carrier should I use for a kids 4G smartwatch?+
Verizon and T Mobile both offer dedicated kids watch plans at $10 to $15 per month. Verizon GizmoWatch uses Verizon; T Mobile SyncUp Kids Watch uses T Mobile. Unlocked watches (TickTalk, Cosmo, Xplora) work with either carrier via a SIM card. AT&T does not currently sell a branded kids watch but supports unlocked models. Pick the carrier based on coverage at home, school, and activity locations. T Mobile band 71 (600 MHz) is strong in rural areas; Verizon has the broadest overall coverage.
Can kids smartwatches be tracked or hacked by strangers?+
Modern certified kids watches use carrier networks (not open WiFi) for cellular which is encrypted and not easily hacked. The parent app uses TLS encryption and requires login credentials. Location data is stored on company servers; pick a brand with US data storage if privacy matters. Approved contact whitelisting means strangers cannot call or message the watch. The main risks are weak parent app passwords (use strong passwords and 2FA) and physical theft of the watch which is rare.
What if the kid loses or breaks the watch?+
Most kids watches survive normal wear, drops, and weather; the Spacetalk Adventurer and TickTalk 5 specifically design for ruggedness. For pool and ocean use IP68 rated watches like Spacetalk Adventurer and Cosmo JrTrack are needed. Replacement bands are usually available and inexpensive. Insurance plans through carriers add $5 to $10 per month and cover loss and damage; useful for younger or rougher kids. Most watches have GPS so a lost watch can usually be located via the parent app.
Is GPS accurate enough to find a kid in real time?+
Yes within 10 to 50 feet outdoors with clear sky. GPS combined with LTE tower triangulation and WiFi positioning provides good accuracy in most situations. Indoor accuracy is worse (50 to 200 feet) since GPS signals are weakened by walls. Updates happen every 1 to 5 minutes depending on battery saving settings; live tracking mode updates every 10 to 30 seconds but drains battery faster. Geofence alerts notify parents when the kid enters or leaves designated zones like home, school, or grandma's house.
