There comes a moment in every family when a child wants a little more independence — walking to a friend's house, staying late at football, exploring the park while you sit on the bench — and you want a simple way to stay in touch without handing over a full smartphone. A kids' smartwatch is the answer a lot of UK parents land on. The best ones let your child call and message a short, locked-down list of approved contacts, share their location, and tap an SOS button if they need you — all while blocking the open internet, app stores and social media that make a phone such a worry for younger children.

The timing is good, too. With the summer holidays here and a new school year in September, a watch is the kind of gift that buys a child a sense of freedom and buys you a little peace of mind. If you'd rather keep things screen-light, there's a second family of watches that skips the SIM card altogether: no-SIM fitness and play watches that count steps, set alarms, run games and snap photos, with no calling, no tracking and no monthly bill.

This guide covers both. We've sorted the UK market into eleven picks for 2026 — seven 4G "watch-phones" with GPS and calling, and four budget no-SIM watches for younger children — spanning a £12.89 first watch to a £189 flagship. Every pick below was confirmed in stock on Amazon UK at the time of writing, with prices correct as of 29 June 2026. Looking for something for a grown-up's wrist instead?

1. XPLORA X6 Play — Best Overall

XPLORA is the brand most UK parents end up trusting, and the XPLORA X6 Play shows why. It's a proper 4G watch-phone — your child can make and take voice and video calls, send text and voice messages, and tap an SOS alert, all to a contact list you approve from the parent app. There is no open web browser, no app store and no social media, which is exactly the point: it does the jobs you want and nothing you don't.

Location tracking and a "safe zone" geofence let you see where your child is and get an alert if they leave school or the park. A standout feature is School Mode, which silences everything but the clock during lesson times, and XPLORA's Goplay app turns steps into in-app rewards, nudging kids to stay active. The body is water-resistant for hand-washing and rainy walks, and there's a camera for the inevitable selfies.

Who it's for: Children roughly 5–11 making their first solo trips who need calling, GPS and a strong parental app from a well-supported UK brand.

Pros:

• Calls, video, messaging and SOS to approved contacts only
• Excellent parent app with geofencing and School Mode
• No internet, app store or social media

Cons:

• Needs a nano-SIM and a monthly plan (sold separately)
• Premium price for the category

2. imoo Watch Phone Z7 — Best for Video Calls

If staying face-to-face matters, the imoo Watch Phone Z7 is the pick. imoo built its reputation on the smoothest video calling in the category, and the Z7 pairs a clear display with dual cameras so grandparents and parents can actually see a beaming face rather than a blurry ceiling. It's a flagship 4G watch-phone with multi-source positioning (GPS plus Wi-Fi and base-station data) for more reliable location fixes in town, where a single GPS chip can struggle.

You also get the safety essentials done well: approved-contacts-only calling and messaging, an SOS button, a class-disable mode for school hours, and a sturdy, splash-friendly build. Battery life is strong for a watch doing this much, comfortably seeing most children through a full school day and the journey home.

Who it's for: Families who video-call a lot and want the most polished calling experience, for children around 6–12.

Pros:

• Best-in-class HD video calling with dual cameras
• Reliable hybrid GPS + Wi-Fi location
• Robust battery and build

Cons:

• The most expensive watch here
• Like all 4G watches, needs its own SIM and plan

Around £189.00 — Check price on Amazon UK →

3. XPLORA XGO 3 — Best Value 4G

The XPLORA XGO 3 keeps almost everything that makes the X6 Play great, trims a few extras, and lands at a friendlier price. You still get 4G calling and messaging to approved contacts, GPS location with safe zones, an SOS alert, a step counter and the same well-regarded XPLORA parent app — including School Mode for lesson times. It's lighter and a touch simpler than the flagship, which actually suits smaller wrists and younger children very well.

What you give up versus the X6 Play is mostly screen polish and camera quality, neither of which is essential when the core job is "let me reach my child and know they're safe." For a lot of families, the XGO 3 is the sweet spot of the whole range.

Who it's for: Parents who want the trusted XPLORA app and safety features without paying flagship money, for children around 5–10.

Pros:

• Full XPLORA safety suite at a mid-range price
• Light and comfortable for smaller wrists
• Same parent app, geofencing and School Mode

Cons:

• Lower-resolution camera than the X6 Play
• Requires a SIM and monthly plan

Around £139.99 — Check price on Amazon UK →

4. imoo Watch Phone Z3 — Best for Ages 6–9

The imoo Watch Phone Z3 is imoo's well-judged middle child: most of the Z7's smarts in a chunkier, knock-resistant body that suits busy younger kids. It handles 4G voice and video calling, messaging and an SOS button, with GPS location feeding back to the parent app, and a class mode to keep it quiet at school. imoo's video calling is again the highlight at this price, and the friendly interface is easy for a six- or seven-year-old to navigate without help.

Build quality is the other reason it lands in this slot — the Z3 is designed to shrug off the drops, splashes and scrapes that come with primary-school life, so it should survive a playground or two.

Who it's for: Newly independent children around 6–9 who'll give a watch a hard life and video-call family often.

Pros:

• Smooth video calls and simple, child-friendly interface
• Durable, splash-friendly design
• Strong value against the flagship Z7

Cons:

• Single rear camera and a plainer screen
• SIM and plan needed (sold separately)

Around £129.00 — Check price on Amazon UK →

5. XPLORA Kidzi — Best Budget Brand-Name 4G

Want a recognised, well-supported brand without the flagship outlay? The XPLORA Kidzi is XPLORA's value entry into 4G watch-phones, slipping under the £100 mark while keeping the features that matter. Your child can call and message approved contacts, send a video call, share their location and fire an SOS, and you get the same dependable XPLORA parent app with safe zones and School Mode behind it all.

It's a sensible "first proper watch" — cheaper than the XGO 3 and X6 Play, but from a brand you can actually get help from if something goes wrong, with regular software updates rather than a no-name watch that's abandoned the day after it ships.

Who it's for: Budget-minded parents who still want a trusted brand and app, for children around 5–10.

Pros:

• Genuine XPLORA app and safety features under £100
• Calling, video, GPS and SOS all present
• Ongoing updates and UK support

Cons:

• Simpler screen and camera than pricier XPLORAs
• SIM and monthly plan required

Around £99.99 — Check price on Amazon UK →

6. imoo Watch Phone Z1 — Best Battery Life

The imoo Watch Phone Z1 is the long-runner of the group. It's an older imoo model, but it has earned a loyal following for stamina — many families report it lasting noticeably longer between charges than flashier rivals, which matters when a child forgets to charge it three nights running. You still get the imoo staples: 4G voice and video calling to approved contacts, messaging, GPS location and an SOS button, plus a class-disable mode for school.

The trade-off for that price and battery life is an older interface and a more modest camera, but if your priority is "it just works and it's still alive at home time," the Z1 delivers — and at £99 it's one of the better-value true watch-phones here.

Who it's for: Forgetful chargers and parents who value reliability over the latest screen, for children around 6–11.

Pros:

• Excellent battery life for a 4G watch
• Proven, durable design with a big following
• Keenly priced video-calling watch-phone

Cons:

• Older interface and camera
• Needs a SIM and plan like all 4G watches

Around £99.00 — Check price on Amazon UK →

7. Blackview 4G Kids Watch — Best Cheap 4G GPS

Here's the surprise of the round-up. The Blackview 4G Kids Watch delivers a genuine 4G GPS watch-phone — calls, two-way video, voice chat, location tracking via GPS, LBS and Wi-Fi, plus an SOS button — for well under fifty pounds. For families who want the safety of calling and location but balk at spending £150–£190, it makes the whole category accessible.

You should temper expectations: the companion app and software polish aren't on XPLORA or imoo's level, video quality is basic, and long-term updates are less certain from a smaller brand. But the core promise — "I can ring my child and see roughly where they are" — is intact, and there's a camera and a few games to keep the watch fun. As a low-risk way to test whether your child will actually wear and use a smartwatch, it's hard to beat.

Who it's for: Cost-conscious parents who want real 4G calling and GPS without a big commitment, for children around 5–10.

Pros:

• True 4G calling, video and GPS at a budget price
• GPS + LBS + Wi-Fi location for better fixes
• Low-risk way to try the category

Cons:

• App and software less refined than the big brands
• Updates and long-term support less certain

8. BIGGERFIVE Kids Smart Watch — Best No-SIM Fitness Watch

Not every family wants calling, location and a monthly bill — and for younger children, many don't. The BIGGERFIVE Kids Smart Watch is our pick of the no-SIM crowd: a self-contained fitness and activity watch with a bright 1.8-inch screen, a pedometer, heart-rate and sleep tracking, an alarm, a handful of games, a camera and a music player. There's no SIM card, no GPS and no calling, so there's nothing to track, no contacts to manage and no running cost — it does everything on the watch itself.

It's rugged and IP68 water-resistant, so it survives puddles and hand-washing, and the activity features genuinely encourage younger kids to get moving. Think of it as a first "grown-up-feeling" watch that builds the habit of wearing one, without any of the connectivity worries.

Who it's for: Children around 4–10 who want a real smartwatch experience — steps, alarms, games — with zero subscription and nothing to track.

Pros:

• No SIM, no GPS, no monthly cost — fully self-contained
• Step, heart-rate and sleep tracking plus games and camera
• IP68 water-resistant and child-tough

Cons:

• No calling or location (by design)
• Games can be a mild classroom distraction

Around £35.99 — Check price on Amazon UK →

9. LODIMEKE Kids Smart Watch — Best Activity Play Watch

The LODIMEKE Kids Smart Watch is another no-SIM option, but it leans into activity and play. The big 1.8-inch touchscreen drives a pedometer with 100-plus "sports modes," a clutch of built-in games, a camera, a music player, alarms and a calendar — plenty to keep a child busy on a long car journey or a wet afternoon without any connectivity at all. As with all the no-SIM watches here, there's no calling, no GPS and no monthly fee.

It's a sensible step down in price from the BIGGERFIVE while keeping the features kids actually play with. The build is plastic and cheerful rather than premium, and battery life is everyday-fine; the appeal is a fun, fuss-free watch that costs less than a video game and needs nothing more than the box.

Who it's for: Active, playful children around 4–10 who want games, a camera and step-counting on a tight budget.

Pros:

• 100+ activity modes, games, camera and music
• Large, responsive touchscreen
• No SIM, no subscription, low price

Cons:

• No calling or location features
• Basic plastic build

Around £23.59 — Check price on Amazon UK →

10. YEDASAH Kids Smart Watch — Best for Games & Camera

If the watch is really about fun, the YEDASAH Kids Smart Watch leans furthest into play. It bundles a stack of puzzle games, a camera for photos and video, a music player, a pedometer and alarms into a colourful, kid-friendly watch aimed squarely at four- to twelve-year-olds. There's no SIM and no GPS, so it's purely an on-wrist toy — which, for a lot of children (and parents), is exactly the right amount of technology.

It makes a brilliant birthday or stocking gift: low cost, instantly entertaining, and nothing for you to set up or pay for each month. Just be aware that the games are the main event here, so it's worth agreeing some "watch away at homework time" rules early on.

Who it's for: Children around 4–12 who mainly want a fun gadget with games and a camera, no strings attached.

Pros:

• Lots of games plus a dual camera and music
• No SIM, no GPS, no running costs
• Fun, affordable gift that needs no setup

Cons:

• Games-first focus can distract from school
• No safety or location features

Around £22.99 — Check price on Amazon UK →

11. kaacly Kids Smart Watch — Best First Watch on a Budget

At well under fifteen pounds, the kaacly Kids Smart Watch is the cheapest way onto the smartwatch ladder. It's a no-SIM play watch with the expected toy-tier mix — simple games, a camera, a music player, a pedometer and alarms — wrapped in a bright, comfortable band sized for small wrists. There's no calling and no location tracking; this is firmly a "first watch" for a young child who mostly wants to feel grown-up and take a few photos.

Set expectations accordingly: the screen and camera are basic, and it won't survive being treated like a sports watch. But as a low-stakes introduction — a party gift, a reward, or a way to see whether your child will even wear a watch before you spend £150 on a 4G one — it does the job for pocket-money money.

Who it's for: Younger children (around 3–8) and anyone wanting the cheapest possible first watch.

Pros:

• Lowest price in the round-up
• Games, camera and step-counting included
• Comfortable, small-wrist-friendly fit

Cons:

• Basic screen, camera and build
• No calling, GPS or durability claims

Around £12.89 — Check price on Amazon UK →

How to Choose a Kids' Smartwatch

The single biggest decision is 4G watch-phone or no-SIM watch — get that right and the rest falls into place.

Do you actually need calling and location? A 4G watch-phone (XPLORA, imoo, Blackview here) lets your child call, message and be located, with an SOS button — ideal once they start travelling without you. A no-SIM watch (BIGGERFIVE, LODIMEKE, YEDASAH, kaacly) does steps, games, a camera and alarms with no tracking and no bill — perfect for younger children or families who simply don't want the connectivity.

Budget for the SIM, not just the watch. Every 4G watch needs its own nano-SIM and a small monthly plan. In the UK you don't need a fancy tariff — a low-cost SIM-only or smartwatch plan (a few pounds a month, often £3–£10) with a little data is plenty. Some networks offer dedicated kids'-watch SIMs. Factor this running cost in before you choose.

Look for the safety basics: approved-contacts-only calling (so strangers can't get through), an SOS button, GPS location with a "safe zone" geofence alert, and a school or class mode that silences the watch during lessons. Crucially, the best kids' watches have no open web browser, no app store and no social media — that absence is a feature, not a limitation.

Mind battery, durability and water resistance. Aim for a watch that lasts a full school day and the trip home, with a water-resistance rating (IP67/IP68) that survives rain and hand-washing. Younger children are hard on hardware, so a chunky, knock-resistant body pays off.

Match it to the age. As a rough guide: no-SIM play and fitness watches suit roughly 3–8, while 4G watch-phones come into their own from about 5–6 upwards as independence grows. If your child is closer to needing a real device, our guide to the best kids' learning tablets UK 2026 and our age-by-age picks for 6–8 year-olds and 9–12 year-olds are worth a look.

Think about data and privacy. A location-tracking watch collects sensitive data about your child, so choose an established brand with a clear privacy policy and servers/processing you're comfortable with. XPLORA and imoo are the most transparent and best-supported brands in the UK market, which is a big part of why they top this list. Cheaper watches can be brilliant value but tend to come with vaguer privacy terms — read them before you buy.

Frequently Asked Questions

Do kids' smartwatches need a SIM card? The 4G "watch-phones" do — calling, messaging and live location all run over a mobile network, so they need their own nano-SIM and a small monthly plan. The no-SIM fitness and play watches (BIGGERFIVE, LODIMEKE, YEDASAH, kaacly) need nothing extra; everything runs on the watch itself with no ongoing cost.

How much does a kids' watch SIM plan cost in the UK? Not much. A basic SIM-only or dedicated smartwatch plan with a little data is usually somewhere around £3–£10 a month — you don't need a full phone tariff. Shop around the major networks and the smaller MVNOs, and look for ones that specifically support smartwatch SIMs.

What age is a kids' smartwatch for? Broadly, no-SIM play and fitness watches suit children from about 3–8, while 4G watch-phones with calling and GPS make most sense from around 5–6 upwards, as a child starts spending time away from you. There's no hard rule — match the watch to your child's independence and how they'll use it.

Can I track my child's location with these watches? Yes, with the 4G models. They use GPS (often combined with Wi-Fi and mobile-network positioning) to show your child's location in the parent app, and most let you set a "safe zone" that alerts you if they leave it. The no-SIM watches do not track location at all.

Are kids' smartwatches safe and private? The reputable 4G watches are designed around child safety: calls and messages are limited to a contact list you approve, there's an SOS button, and there's no open internet, app store or social media. Because location watches do collect personal data, stick to established brands such as XPLORA and imoo with clear, UK-friendly privacy policies, and review the terms before buying.

What about Garmin Bounce, Spacetalk or TickTalk? They're all well-regarded kids' watches. We didn't feature the Garmin Bounce and vívofit Jr.3 here because their Amazon UK stock was thin and prices were inflated at the time of writing — and an affiliate link to a near-out-of-stock product helps nobody. The Garmin vívofit Jr.3 is an excellent no-SIM fitness/chores watch if you can find it well-priced, while Spacetalk and TickTalk are often bought direct from the brand rather than Amazon. If you specifically want one of those, check availability directly.

Do these watches work without the parent's phone nearby? The 4G watches work independently once set up — your child can call and be located whether or not your phone is with them, because the watch has its own connection. The no-SIM watches are entirely standalone and never needed a phone in the first place.

The Verdict

For most UK families in 2026, the XPLORA X6 Play is the best all-round kids' smartwatch — a trusted brand, a genuinely good parent app, and all the safety features that matter, with none of the smartphone worries. If video calling is your priority, the imoo Watch Phone Z7 is the one to beat, while the XPLORA XGO 3 hits the value sweet spot for the same peace of mind for less.

On a tighter budget, the Blackview 4G Kids Watch brings real calling and GPS under £45, and if you'd rather skip SIMs and subscriptions entirely, the BIGGERFIVE is a brilliant no-strings fitness watch for younger children — with the playful YEDASAH and pocket-money kaacly rounding out the fun, fuss-free end.

Whichever you choose, a kids' smartwatch is one of those rare gifts that gives a child a taste of independence and gives you a little reassurance at the same time. For more ways to keep curious minds busy this summer, browse our guide to the best STEM toys UK 2026.
