10 Best Smartwatch With Cellular 2025 in the United States

The Apple Watch Series 10 (46mm, GPS + Cellular) is a strong pick if you want a smartwatch that works well without your iPhone nearby. Thanks to cellular connectivity, you can make calls, send texts, and stream music right from your wrist. Its battery life covers a full day with about 18 hours of normal use, and fast charging can get you back to 80% in just 30 minutes, which is convenient if you’re on the go.

This watch is designed to work smoothly with Apple devices, so if you have an iPhone (Xs or newer with iOS 18+), the compatibility is seamless.

The larger, brighter Always-On Retina display makes it easy to see your stats and notifications clearly.

Durability is solid with dust resistance (IP6X) and crack-resistant glass, making it a good companion for active or outdoor use. Safety features like fall detection and crash detection add peace of mind by automatically contacting emergency services if needed. While the battery life might require daily charging if many features are used extensively, this watch works best within the Apple ecosystem. Although the app selection is broad, it is primarily focused on Apple’s own apps and services, which might limit customization compared to some competitors.
