Kids Smart Watch 4G LTE with GPS, Video Call, SOS and Geofence (Black)
The Emojikidz Kids Smart Watch is designed for parents who prioritize a walled garden over open internet access. Like the SmartPro, it offers 4G LTE two-way calling and GPS tracking, but its interface is even more restricted. There is no open internet or social media access, meaning children can only communicate with pre-approved contacts. This is a significant advantage over the Samsung Galaxy Watch Ultra, which allows app downloads, but it is comparable to the SmartPro in terms of security philosophy. The SOS button automatically dials multiple contacts, providing a safety net in emergencies.
Compared to the SmartPro, the Emojikidz model has slightly lower water resistance (39 inches), making it less suitable for active play in wet conditions. The internal storage is limited to 128 MB, which is enough for basic data and photos but not for storing media. The parental control app is straightforward, allowing you to manage contacts and set classroom modes easily. This watch is ideal for younger children who do not need the advanced features of a smartphone yet. It delivers on the promise of independent calling by ensuring that the only calls made are those explicitly permitted by the parent, reducing anxiety about unknown callers.
Pros:- No open internet or social media access for enhanced safety

- Water Resistance:Water Resistant (39 inches)
- Storage:128 MB
- Key Features:GPS, Video Call, SOS, Geofence, Activity Tracker
- Compatibility:Android, iPhone
- Age Range:4-12 Years
- Band Material:Resin
Our verdict“This watch is the safest option for young children, prioritizing strict contact control over feature richness.”
Kids Smart Watch – Safe First Phone, GPS Tracker, Video & Voice Calling (Blue)
The Safe First Phone Kids Watch is the most simplified option in this lineup, targeting children as young as three years old. It provides the core benefits of independent calling: 4G LTE voice and video calls and GPS tracking. Unlike the more complex Samsung or even the feature-rich SmartPro, this device removes almost all extraneous functions. There is no open internet, no app store, and no unknown caller capability. This simplicity is its greatest strength for the youngest demographic. The parental control app allows you to manage contacts and activate classroom mode, ensuring the watch does not distract during school hours.
Compared to the Emojikidz and SmartPro models, the Safe First Phone offers fewer advanced health or activity metrics. It is purely a communication and safety tool. The design is lightweight and the interface is minimal, reducing the chance of accidental inputs by small hands. However, this minimalism means fewer features for older children who might grow out of it quickly. It requires the same monthly cellular subscription as its competitors, which is a consistent cost barrier. For parents who want a “just-in-case” communication device without the learning curve of a smartphone, this is the most direct path to independent calling for toddlers.
Pros:- Extremely simple interface for young children
- Real-time GPS tracking with geofence alerts
- SOS emergency button for instant contact
- No open internet or social media access
Cons:- Requires a monthly subscription for connectivity

- Only pre-approved contacts can call
Best for: Parents of toddlers and preschoolers who need a basic, no-frills communication device with location tracking.
Not ideal for: School-age children who want to play games or use educational apps, or parents wanting advanced health tracking.
- Connectivity:4G LTE
- Age Range:3-12 Years
- Key Features:GPS, Video Call, SOS, Parental Controls
- Subscription:Required ($11/month)
- Color:Blue
- Internet Access:None (Closed System)
- Contact Control:Pre-approved only
Our verdict“The simplest and most age-appropriate choice for the youngest children needing independent calling.”
How We Picked
To curate this list, I filtered devices based on a strict criterion: independent cellular connectivity. I excluded any smartwatch that relies solely on Bluetooth tethering to a smartphone for calls. I prioritized devices with LTE or 4G capabilities that allow for voice and data transmission directly from the wrist. For the adult category, I focused on build quality, display visibility, and battery efficiency during LTE usage. For the kids’ category, I evaluated the reliability of GPS tracking, the clarity of two-way video calling, and the robustness of parental control apps. I also considered the ease of setup for cellular plans, as complex carrier configurations can be a barrier to entry. Devices that required obscure carriers or lacked clear coverage maps were excluded. The final selection balances durability, communication quality, and specific use-case suitability, ensuring that every recommended watch delivers on the promise of phone-free independence.

Factors to Consider When Choosing Smartwatch With Two Way Calling Independent
Choosing a smartwatch with independent calling requires understanding the difference between Bluetooth tethering and cellular autonomy. Here is what you need to know before buying.Understanding Cellular Connectivity (eSIM vs. SIM)
Most adult smartwatches use eSIM technology, which is embedded in the device. You activate a plan through your carrier’s app, and the watch shares your phone number. This is convenient but requires a compatible carrier and a monthly fee. Kids’ watches often use physical Nano SIM cards or proprietary eSIMs that require specific subscription plans from third-party providers. Unlike Bluetooth watches, these devices cannot make calls if the SIM is inactive or if there is no cellular signal. I recommend checking coverage maps in your area before purchasing, as rural areas may have limited 4G LTE coverage for these specific devices.
Battery Life and LTE Usage
Independent calling consumes significant power. The GPS and LTE radios are the primary battery drains. When a watch is searching for a signal or maintaining a data connection, the battery depletes much faster than when connected via Bluetooth. For adults, the Samsung Galaxy Watch Ultra manages this well with power-saving modes, but you should expect to charge daily if you rely heavily on LTE. For kids, the SmartPro offers about three days of life, but this assumes moderate usage. If you use video calling frequently, expect to charge the kids’ watch every other day. Always prioritize devices with at least 500 mAh batteries if you plan to use independent features regularly.
Parental Controls and Safety Features
For kids’ watches, the software ecosystem is just as important as the hardware. Look for watches with dedicated parental control apps that allow you to whitelist contacts. This prevents unknown numbers from reaching your child. Features like geofencing (alerts when the child leaves a designated area) and SOS buttons are standard. The Emojikidz and Safe First Phone models excel here by blocking open internet access, creating a safe digital environment. In contrast, adult watches like the Samsung offer open app access, which requires self-discipline rather than parental oversight.
Frequently Asked Questions
Do I need a separate phone number for a smartwatch with independent calling?
It depends on the device. For adult watches like the Samsung Galaxy Watch Ultra, you typically use a “number share” feature where the watch shares your existing phone number via eSIM. This allows calls to ring on both devices. For many kids’ watches, you may need a separate number or a dedicated plan linked to a parent’s account, depending on the carrier’s policy. Always verify with your provider whether they support “number share” for smartwatches or if they require a separate line.Can I use a smartwatch with independent calling without a smartphone?
Yes, that is the primary purpose of these devices. Once the cellular plan is activated, the watch can make and receive calls, send messages, and use data independently. However, most watches require a smartphone for the initial setup, firmware updates, and syncing health data. You cannot completely eliminate the smartphone from your life; you just eliminate the need to carry it during specific activities like running or school hours.How does GPS accuracy compare between kids’ watches and adult watches?
Adult watches like the Samsung Galaxy Watch Ultra generally have more precise GPS chips optimized for fitness tracking and route mapping. Kids’ watches use GPS primarily for location safety, so the accuracy is sufficient for determining which street or neighborhood a child is in, but it may not be precise enough for turn-by-turn navigation. For safety purposes, the SmartPro and Emojikidz models are accurate enough to trigger geofence alerts reliably.Are there smartwatches with good battery life that support independent calling?
Battery life is always a compromise with LTE models. The Samsung Galaxy Watch Ultra is one of the better performers, offering up to 40 hours of standard use and 100 hours in power-saving mode. Kids’ watches like the SmartPro offer around three days, but this drops significantly with video calls. If battery is your priority, look for devices with larger mAh ratings (500+ for adults, 700+ for kids) and consider using power-saving modes when independent connectivity is not critical.Can kids’ smartwatches access the internet or social media?
Most dedicated kids’ smartwatches, such as the Emojikidz and Safe First Phone models, explicitly block open internet and social media access. They operate on closed systems where children can only communicate with pre-approved contacts. This is a key differentiator from adult smartwatches, which often allow app downloads and web browsing. Parents should choose closed-system watches if they want to ensure their child cannot access inappropriate content.Conclusion
Choosing the right smartwatch with two-way calling independent of a phone depends entirely on who is wearing it. For adults, the Samsung Galaxy Watch Ultra is the clear winner. Its titanium build, LTE connectivity, and advanced health tracking make it a capable companion for those who want to leave their phone behind. It is the best option for hikers, runners, and professionals who need reliable, standalone communication.
For parents, the decision rests on the child’s age and your comfort level with technology. The SmartPro Smart Watch is the best overall choice for school-age children, offering the best balance of video call quality and GPS accuracy. If you have a younger child or want to strictly limit their digital exposure, the Emojikidz Kids Smart Watch provides a safer, closed system. For the youngest children, the Safe First Phone model is the simplest entry point. All kids’ watches require a monthly cellular subscription, so factor that into your long-term costs. Ultimately, the best watch is the one that fits your lifestyle while providing the peace of mind that comes with staying connected, no matter where you are.
