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 Apple Watch Ultra 3 is a robust smartwatch designed especially for sports and outdoor adventures, featuring a rugged titanium case and sapphire crystal display that holds up well to tough conditions and water activities up to 100 meters deep. Its cellular connectivity supports fast 5G, allowing you to make calls, stream music, and send texts without needing your iPhone nearby, which is great for staying connected on the go. The battery life is strong, lasting up to 42 hours under normal use and extending to 72 hours with power-saving mode, enough to cover several days of activities without frequent recharging.

The watch offers advanced health monitoring, including heart rate, blood oxygen, ECG, sleep tracking, and alerts for issues like irregular heart rhythms and hypertension, making it a great companion for health-conscious users. Its bright, always-on Retina display is easy to read even in bright sunlight and can be used as a flashlight, adding practical convenience. The built-in GPS is precise with dual-frequency support, helping with accurate tracking during runs, hikes, and other workouts. Apple’s ecosystem brings a wide array of apps and seamless integration with iPhones, enhancing user experience.

One consideration is that the watch is quite large and may feel bulky for some wrists, and it only works with newer iPhones (iPhone Xs or later), limiting compatibility. Also, the premium price and titanium build reflect a high-end product that may be more than casual users need. For those seeking a durable, feature-packed smartwatch that keeps you connected anywhere while providing in-depth fitness and health insights, the Apple Watch Ultra 3 stands out as a strong choice.

The Apple Watch SE 3 with GPS + Cellular offers a strong package for anyone looking for a smartwatch that can keep you connected on the go without needing your phone nearby. Its 5G and LTE cellular connectivity means you can send texts, make calls, and access emergency services independently. The battery life supports up to 18 hours of regular use, which comfortably covers a full day, and it charges quickly—up to 8 hours of use in just 15 minutes—making it convenient for daily wear.

This model is packed with health and fitness features such as heart rate monitoring, temperature sensing, sleep tracking with detailed sleep scores, and alerts for irregular heart rhythms or sleep apnea. These tools give you useful insights about your wellbeing without extra effort. The always-on Retina display is bright and clear, letting you check the time and notifications without lifting your wrist. The screen is also tough, with a front glass designed to resist cracks.

Durability is decent with water resistance suitable for everyday activities including swimming. The watch also offers safety features like fall detection and crash detection that can automatically call for help if needed, which adds peace of mind. Compatibility with iPhones is seamless, and the watch supports Apple's extensive app ecosystem, allowing you to customize watch faces and download various apps to enhance your experience. It also includes features geared toward kids, like allowing calls and location sharing without their own iPhone. While the battery life is solid for a day, it is shorter than some other smartwatches that can last multiple days without charging. Additionally, it is designed mainly for iPhone users, so it isn’t an ideal choice if you use Android. This makes the Apple Watch SE 3 a well-rounded option for those who want a stylish, health-focused smartwatch with reliable cellular connectivity and a vibrant app ecosystem, especially if you’re already in the Apple ecosystem.
