Detailed Reviews
Emojikidz Smartwatch for Kids with 4G LTE GPS Tracker
Best for: Families considering this exact model or bundle
Ages: Ages 3+
If your household has never set up a kids’ smartwatch before, the Emojikidz 4G LTE model stands out for one important reason: it runs on the brand’s own cellular plan rather than requiring you to source a compatible SIM from a separate carrier. According to the seller, the plan starts at around $9 per month, and the watch is not compatible with other carriers — so what you see is what you get, for better or worse. On the feature side, the watch offers 4G LTE real-time GPS tracking, two-way calling and texting with parent-approved contacts, an SOS emergency button, school/classroom mode, an alarm clock, pedometer, and built-in games. It is listed as IP67 splash resistant, which offers some reassurance for active kids, though IP67 is not the same as fully waterproof. The locked-in carrier means setup is more straightforward than hunting for SIM compatibility, but it also means you cannot switch plans if pricing or coverage disappoints. If you travel internationally or want carrier flexibility, look elsewhere.
Buy this if you want a clear, guided path to getting a GPS watch up and running without sourcing your own SIM.
Skip this if you want carrier choice, video calling, or international coverage.
Kids Smart Watch with GPS Tracker Video Call SOS Alerts Preinstalled SIM
Best for: Families considering this exact model or bundle
Ages: Ages 3+
The second Emojikidz entry solves a pain point that frustrates many first-time buyers: the SIM card is already installed in the watch. That removes one of the trickier setup steps, though you will still need to activate a cellular plan subscription before GPS tracking and calling work. This model adds video calling and an HD camera on top of the audio-call-and-text foundation, which is a meaningful upgrade for kids who want to see a parent’s face when they check in. School mode and SOS alerts round out the safety-focused features, and the parental control app gives you oversight of contacts and settings. The seller notes that carrier and plan costs should be confirmed on the listing before purchase, because those details can change. If preinstalled hardware convenience plus video calling is your priority, this Emojikidz version has a clear edge over the base model.
Buy this if you want video calling and the convenience of a SIM already in the box.
Skip this if you need carrier flexibility or want to avoid any subscription commitment.
4G Kids Smart Watch GPS Tracker with Video Calling Voice Chat Class Mode
Best for: Families considering this exact model or bundle
Ages: Ages 4+
The Lurkir watch puts video calling at the center of its pitch, and its HD touchscreen supports both video and voice chat. Real-time 4G GPS tracking, class mode, SOS button, pedometer, and alarm cover the expected safety and school-day bases. The critical difference from the Emojikidz models: the SIM card is not included and must be purchased separately. That gives you more carrier flexibility — useful if you already have a family plan you want to add a line to — but it also means one more step before the watch works. Confirm your carrier is compatible before ordering. The seller describes the watch as suited for ages 4–12 boys and girls. If your family already knows which carrier you want to use and video calling is the feature your child will use most, this is a strong contender.
Buy this if video calling is the top priority and you are comfortable activating your own SIM from a compatible carrier.
Skip this if you want everything ready to go out of the box, or if you are unsure about carrier compatibility.
4G Kids Smart Watch GPS Tracker Two Way Call Video Calling SOS Games
Best for: Families considering this exact model or bundle
Ages: Ages 3+
The tykjszgs watch aims to cover every feature a parent might want in a single device: 4G real-time GPS, two-way audio calling, video calling, voice chat, SOS, class mode, stopwatch, pedometer, games, alarm clock, and — notably — Wi-Fi support in addition to cellular. That Wi-Fi connectivity means the watch can stay partially functional on home or school networks even if cellular coverage is weak, which is a practical advantage other options on this list don’t explicitly offer. A SIM card is required; confirm the current details on the listing before purchasing. A parental app is required for setup and controls. The breadth of features makes this watch appealing for families who want maximum functionality, though more features also means more settings to manage and more for a child to get distracted by during school hours.
Buy this if you want the widest range of features — especially Wi-Fi as a backup to cellular — and don’t mind a slightly more involved setup.
Skip this if you prefer a simpler watch with fewer distractions, or if SIM sourcing is a dealbreaker.
Wonlex Kids Smart Watch with SIM Card 4G GPS Tracker
Best for: Families considering this exact model or bundle
Ages: Ages 4+
Most kids’ GPS watches on the market do not support WhatsApp, which is still the dominant messaging app for families with relatives abroad or parents who travel internationally. The Wonlex watch explicitly supports both WhatsApp and Line, which is a meaningful differentiator if your family communicates through those platforms. It includes real-time 4G GPS tracking, calling, voice messages, an SOS button, and an HD camera. A SIM card is included in the box, but a cellular plan is still required, and you should check carrier compatibility before purchasing. The seller notes international use is supported. The listing describes it as suitable for ages 4–16. If your extended family relies on WhatsApp or you need a watch that can function across borders, this is the only option in this group that directly addresses that need.
Buy this if your family uses WhatsApp or Line, or if you need international messaging support built into the watch.
Skip this if you have no need for international app support and prefer a more domestically focused setup.
How to Choose
Before buying any GPS tracker for kids, answer these four questions:
- SIM included or not? Some watches include a SIM card; others require you to source one. Neither is automatically better, but knowing in advance prevents a frustrating unboxing experience.
- What is the ongoing cost? Every watch on this list requires a cellular plan subscription. Budget for that monthly expense before you decide the upfront price is affordable.
- Is your carrier compatible? The Emojikidz 4G LTE model (B0F7FSXT6D) only works on its own plan. The Lurkir requires you to bring your own SIM. Others include a SIM but may have carrier restrictions. Always check the listing before ordering.
- Which features will actually get used? Video calling, games, and pedometers sound appealing, but more features mean more complexity — and more potential classroom distractions. Match the feature set to your child’s age and your family’s habits.
Frequently Asked Questions
Do all kids’ GPS watches require a monthly subscription?
Every watch in this guide requires a cellular plan to enable GPS tracking and calling. The cost and carrier vary by product, so check each listing for current plan details before purchasing.
Is a preinstalled SIM the same as a ready-to-use plan?
No. A preinstalled SIM means the hardware is already in the watch, but you still need to activate and pay for a cellular plan separately before the watch can connect to a network.
How accurate is GPS tracking on these watches?
GPS location accuracy depends on signal environment, network coverage, and the watch’s firmware. Urban areas with strong 4G coverage generally perform better than rural or indoor settings. No GPS tracker for kids offers guaranteed real-time pinpoint accuracy in all conditions.
Can my child use the watch at school?
All five watches include a school or class mode that restricts features during school hours. Check your school’s specific policy on smartwatches before purchasing.
Final Recommendations
If you are brand new to kids’ smartwatches and want the simplest possible setup, the Emojikidz 4G LTE GPS Smartwatch offers a guided subscription path without SIM shopping. For families who want video calling and a SIM already in the device, the Emojikidz Preinstalled SIM model adds that capability. The Lurkir is the right fit if video calling matters and you want to choose your own carrier. The tykjszgs watch stands out if you want the broadest feature set — especially its Wi-Fi support. And if WhatsApp or international messaging is a household staple, the Wonlex is the only watch here that directly addresses that need. Whichever you choose, confirm the current SIM situation, plan cost, and carrier compatibility on the Amazon listing before adding to cart.
