Compact LTE smartwatch for standalone connectivity

The Samsung Galaxy Watch4 combines a 44mm aluminum case with built-in LTE so you can leave your phone behind and still take calls, stream music or receive notifications. Its 16GB of onboard storage holds apps and offline playlists for workouts or travel. The fluoroelastomer sport band secures the 30.3g body comfortably during daily wear.

Thermals noise and power in everyday use

The watch runs cool against the wrist during typical activity tracking and LTE sessions, with no audible fan or moving parts to generate noise. Power draw scales with cellular use; expect a full day of mixed Bluetooth and LTE connectivity before the magnetic charger is needed. The 9.8mm profile keeps the sensor array close to the skin for consistent heart-rate and SpO₂ readings.

Included band and grade impact on experience

The supplied black fluoroelastomer sport band is sweat-resistant and quick to swap using the standard spring-bar mechanism. Because this unit is graded B, the aluminum bezel may show dents, chips or scuffs, and the screen may carry hairline scratches that do not affect touch response. Non-OEM accessories may be present in the box.

Questions about this item

How do I activate the LTE service on the 44 mm model?

Insert a compatible nano-SIM or activate an eSIM profile through your carrier app, then pair the watch with the Galaxy Wearable app on your phone to complete the standalone connection setup.

What maintenance will the fluoroelastomer sport band need over time?

Rinse the band with fresh water after sweat or salt exposure, dry it thoroughly, and replace it if cracks or permanent deformation appear from prolonged UV or chemical contact.

What is the first limit I will hit during a long GPS-plus-LTE workout?

The 30.3 g aluminum case houses a battery that typically depletes after several hours of continuous GPS and LTE use, so endurance sessions will hit the power limit first.
