10 Best Smartwatch With Cellular 2025 in the United States

The Apple Watch Series 10 (46mm, GPS + Cellular) is a strong pick if you want a smartwatch that works well without your iPhone nearby. Thanks to cellular connectivity, you can make calls, send texts, and stream music right from your wrist. Its battery life covers a full day with about 18 hours of normal use, and fast charging can get you back to 80% in just 30 minutes, which is convenient if you’re on the go.

This watch is designed to work smoothly with Apple devices, so if you have an iPhone (Xs or newer with iOS 18+), the compatibility is seamless. For health and fitness, it offers advanced features like ECG for heart monitoring, sleep tracking including sleep apnea alerts, cycle tracking, and detailed workout metrics for many activities, even swimming, thanks to its 50-meter water resistance. The larger, brighter Always-On Retina display makes it easy to see your stats and notifications clearly.

Durability is solid with dust resistance (IP6X) and crack-resistant glass, making it a good companion for active or outdoor use. Safety features like fall detection and crash detection add peace of mind by automatically contacting emergency services if needed. While the battery life might require daily charging if many features are used extensively, this watch works best within the Apple ecosystem. Although the app selection is broad, it is primarily focused on Apple’s own apps and services, which might limit customization compared to some competitors. The Apple Watch Series 10 is an excellent choice for anyone invested in Apple products looking for a cellular smartwatch that offers comprehensive health monitoring, reliable connectivity, a bright display, and strong durability.

The Apple Watch Series 10 (GPS + Cellular, 42mm) is a strong choice if you want a smartwatch that works independently from your iPhone thanks to its cellular connectivity. You can make calls, send texts, and stream music without carrying your phone, which is great for staying connected on the go. The display is bigger and brighter than before, making it easy to see your stats and notifications even outdoors. It’s also very durable, with water resistance up to 50 meters and dust resistance, so it can handle swims and outdoor activities well.

For health and fitness, it offers advanced features like ECG readings, heart rate alerts, sleep tracking including signs of sleep apnea, and detailed workout metrics for a wide range of exercises, including swimming and cycling. The safety features such as fall and crash detection add peace of mind by automatically calling for help if something serious happens. Battery life typically lasts about 18 hours with normal use, which means you’ll likely need to charge it daily, but fast charging can get you up to 80% in just 30 minutes.

Compatibility is limited to newer iPhones (iPhone Xs and later) running iOS 18 or higher, so it works best if you’re already in the Apple ecosystem. The watch supports a rich app ecosystem and customizations, allowing you to tailor it to your style and needs. If you don’t use an iPhone or prefer longer battery life without daily charging, this may not be the ideal pick.

The Samsung Galaxy Watch 7 40mm LTE is a strong choice if you want a smartwatch that works independently with cellular connectivity, letting you stay connected without your phone nearby. It shines in health and fitness with features like advanced heart rate tracking, sleep monitoring (including sleep apnea detection), and personalized wellness tips powered by AI, helping you understand and improve your daily energy and workout performance. The touchscreen display is clear and lightweight, making it comfortable to wear throughout the day.

Its durability and water resistance make it suitable for everyday use and workouts. Compatibility with Samsung phones is seamless, though users of other Android or iPhones might find some features limited compared to Samsung devices. Battery life is decent for a watch with always-on LTE but expect to recharge it daily or every other day depending on use.

The app ecosystem is solid, offering plenty of health and fitness apps, but it’s not as extensive as some competitors like Apple Watch. If you want a smartwatch with reliable cellular service, accurate health tracking, and helpful AI-driven insights, this watch covers those well. However, if you prioritize longer battery life or broader app options, you may want to consider alternatives.
