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 Apple Watch Series 10 is a strong contender in the smartwatch-with-cellular category, offering a blend of advanced health tracking, fitness features, and seamless connectivity. One of its standout strengths is the cellular capability, allowing users to make calls, send texts, and stream music even without their iPhone close by. This is particularly beneficial for those who want to stay connected while exercising or on the go.

The health and fitness features are impressive, with capabilities such as an ECG app, heart rate notifications, and sleep tracking. The watch can also monitor menstrual cycles, making it a useful tool for overall wellness. The Activity Rings encourage users to stay active throughout the day and the variety of workout modes cater to a wide range of physical activities.

In terms of design, the Apple Watch Series 10 boasts a larger and brighter display, which is easy to read in various lighting conditions. Its lightweight and comfortable feel is ideal for all-day wear. The watch is also durable, with IP6X dust resistance and a water resistance rating of 50 meters, making it suitable for swimming and outdoor activities.

However, there are a few drawbacks to consider. The battery life, while decent, only lasts up to 18 hours with regular use, which may require frequent charging for heavy users. Additionally, it is primarily designed to work with iPhones, so users with other smartphone brands won't be able to take full advantage of its features.

Customization options are a plus, allowing users to personalize their watch with different bands and faces. It's also worth noting that the environmental commitment of Apple, with the Series 10 being carbon neutral when paired with select bands, adds a socially responsible touch.

For anyone looking for an all-in-one health and fitness tool that offers cellular connectivity, the Apple Watch Series 10 is an excellent choice, especially for existing Apple ecosystem users.

The Apple Watch Ultra 2 is a top choice for those seeking a rugged, feature-packed smartwatch with cellular capability that functions well even without an iPhone nearby. Its 49mm titanium case is tough and corrosion-resistant, with water resistance up to 100 meters, making it ideal for outdoor activities like swimming, diving, and hiking. The super bright Always-On Retina display ensures easy visibility of stats in any lighting condition. Cellular connectivity enables calls, texts, music streaming, and navigation without a phone, adding significant convenience.

Battery life impresses for a smartwatch with such features, lasting up to 36 hours on a single charge and extending to 72 hours in Low Power Mode, reducing the need for daily charging during long trips or workouts. The watch supports the latest watchOS, providing access to a rich app ecosystem and smooth compatibility with iPhones. Advanced health and fitness tracking include precise heart rate monitoring, ECG, sleep tracking, and irregular rhythm notifications. Specialized metrics cater to runners, cyclists, hikers, swimmers, and divers, with features like dual-frequency GPS, offline maps, automatic workout detection, and dive computer functionality.

A notable consideration is the watch’s large size, which may feel bulky on smaller wrists. It is primarily designed for iPhone users, making it less suitable for Android phone owners. While priced higher than many other smartwatches, the cost reflects its durability, detailed fitness tracking, and seamless cellular functions. For active individuals seeking a rugged, reliable smartwatch with cellular freedom and robust health features, the Apple Watch Ultra 2 stands out as an excellent option that blends toughness with smart technology, especially beneficial for sports enthusiasts and outdoor adventurers.
