10 Best Smartwatch With Cellular 2025 in the United States

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.

The Apple Watch SE (2nd Gen) offers robust cellular connectivity, allowing you to stay connected, send texts, make calls, and stream content without needing your iPhone nearby. This makes it convenient for those who are often on the move. With a battery life that typically lasts up to 18 hours, it may require daily charging, which might be a bit inconvenient for some users.

Compatibility is seamless with Apple devices, enhancing connectivity and usability for Apple users. Health and fitness features are strong points, including heart rate monitoring, fitness tracking, sleep analysis, and safety features like Fall Detection and Crash Detection. The Retina display ensures clear and sharp visuals, though the 40mm size may be too small for some users preferring larger screens.

Durability is impressive with 50m water resistance and a Midnight Aluminum Case, making it suitable for everyday wear and swimming. The app ecosystem is extensive, given Apple's vast range of apps and services. One drawback is its reliance on the Apple ecosystem, which might not appeal to Android users. Additionally, while it's customizable with various bands, it comes in only three finishes, limiting personalization options slightly. The Apple Watch SE (2nd Gen) is ideal for individuals seeking an efficient, health-focused smartwatch with robust connectivity, especially those already invested in the Apple ecosystem.
