10 Best Smartwatch With Cellular 2025 in the United States

The Apple Watch Ultra 2 is designed as a high-end, rugged smartwatch with cellular capabilities, ideal for active users who want a durable device for sports and outdoor adventures. Its cellular feature lets you make calls, send texts, and stream music without needing your iPhone nearby, providing strong independence. The battery life is impressive for this category, lasting up to 36 hours in normal use and extending to 72 hours in a low power mode, which is great for longer trips or intense activities.

Compatibility is seamless if you use an iPhone, thanks to watchOS 10 and a broad app ecosystem supporting fitness, navigation, and health monitoring. Health and fitness features are advanced, offering detailed metrics for runners, cyclists, swimmers, and hikers, along with safety tools like fall detection and emergency SOS. The display is bright and easy to read even in sunlight, with a large 49mm titanium case and scratch-resistant sapphire crystal enhancing durability. Water resistance up to 100 meters and military standard testing add to its toughness.

The watch is quite large and may feel bulky for some users, especially those with smaller wrists. It is primarily designed for iPhone users, limiting compatibility with Android devices. While it offers many advanced features, the price reflects its premium positioning, which might be a consideration for those seeking a more budget-friendly cellular smartwatch. This model is well suited for outdoor enthusiasts and athletes looking for a reliable, feature-rich smartwatch that can handle demanding environments and provide strong health, safety, and connectivity support.

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.
