A smartwatch with LTE (or 4G) connectivity allows users to stay connected even when away from their smartphones. Whether making calls, receiving messages, or accessing apps, these devices ensure seamless communication—ideal for workouts, emergencies, or simply leaving the phone behind.
Leading brands like Apple, Samsung, and Google integrate critical safety features that rely on LTE connectivity, making Bluetooth-only models significantly less functional. While cellular models come with higher upfront costs and monthly carrier fees, the added independence and security justify the investment.
Below, we explore the top LTE smartwatches available today and what to consider before purchasing.
Key Factors When Choosing an LTE Smartwatch
Price
LTE-enabled smartwatches typically cost more than their Bluetooth counterparts, and users must also factor in a monthly data plan. Assess whether the standalone connectivity aligns with your needs before committing.
Features
Beyond cellular support, prioritize features like accurate GPS, heart rate monitoring, emergency SOS, and health insights. A well-rounded smartwatch should enhance both convenience and safety.
Battery Life
Cellular connectivity drains battery faster than Bluetooth usage. If LTE is a priority, opt for models with extended battery life or power-saving modes.
Compatibility
Ensure the smartwatch works with your smartphone. Apple Watches pair exclusively with iPhones, while Wear OS (Google Pixel Watch, Samsung Galaxy Watch) and Huawei models are Android-compatible.
Top LTE Smartwatches in 2025
Apple Watch Series 10 (GPS + Cellular)
The Apple Watch Series 10 remains a top choice for iPhone users, offering seamless call, message, and app functionality via eSIM. Despite its premium price, its reliability and performance justify the cost.
Google Pixel Watch 3 LTE
Android users will appreciate the Pixel Watch 3’s smooth integration with Google services like Maps and Wallet. While the 45mm model offers multi-day battery life, LTE usage shortens endurance—especially on the smaller 42mm variant.
Samsung Galaxy Watch Ultra
Samsung’s flagship LTE smartwatch delivers robust connectivity and premium build quality. However, its battery life trails behind competitors like the Apple Watch Ultra 2.
Huawei Watch 5
Huawei’s LTE model excels in health tracking but lacks third-party app support. Its eSIM functionality enables calls and messages, though battery life dips with always-on display and LTE active.
Apple Watch SE (2nd Gen, GPS + Cellular)
A budget-friendly entry into Apple’s LTE lineup, the SE 2 handles calls, notifications, and music streaming. However, an upgrade is expected in late 2025.
Apple Watch Ultra 2
With LTE as standard, the Ultra 2 is ideal for outdoor enthusiasts. Its rugged design and 36-hour battery life (18 hours with LTE) make it a standout—though an Ultra 3 refresh is rumored.
Garmin Forerunner 945 LTE (US Only)
Garmin’s sole LTE model focuses on safety with LiveTrack and emergency alerts. While outdated compared to newer Forerunners, it remains an option for runners needing connectivity.
