10 Best Smartwatch With Cellular 2026 in the United States

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 Fitbit Sense 2 is an advanced health and fitness smartwatch featuring an array of tools to help manage stress and sleep, along with extensive health monitoring capabilities. One of its major strengths is the comprehensive health tracking system, which includes stress detection, ECG app, SpO2 monitoring, 24/7 heart rate, and a personalized sleep profile. The built-in GPS and over 40 exercise modes make it a strong contender for fitness enthusiasts. Additionally, its water resistance up to 50 meters adds to its durability and suitability for various activities.

Design-wise, it offers a comfortable silicone band and customizable clock faces for everyday wear. The inclusion of both small and large bands ensures a good fit for different wrist sizes. With a battery life of over 6 days, users won't have to worry about frequent recharging. However, the lack of direct cellular connectivity may be a drawback for those looking for a truly independent smartwatch experience. It can handle on-wrist Bluetooth calls, texts, and phone notifications, but it must be paired with a smartphone for these features to work.

Compatibility with both iOS and Android devices is a plus, though some features like Google Maps are currently limited to Android. The app ecosystem, featuring Amazon Alexa and upcoming Google Wallet integration, is robust but may not match the extensive options available on other platforms. In summary, the Fitbit Sense 2 excels in health and fitness tracking, design, and battery life, but those seeking full cellular functionality might need to look elsewhere.

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.
