Galaxy Watch 4 40mm LTE Black

The Samsung Galaxy Watch 4 is a 40mm smartwatch with LTE connectivity designed for adults who want comprehensive health tracking on the wrist. It pairs with a compatible smartphone to deliver notifications, messaging and fitness insights throughout the day.

Setup and common issues

Pairing the watch with the companion app on your phone is straightforward and activates the LTE service. The main friction point is ensuring the paired smartphone meets the compatibility requirements so that ECG, sleep analysis and fall detection data sync correctly.

Questions about this item

How can I verify the ECG monitor is working correctly after pairing the watch with my phone?

Open the Samsung Health Monitor app on your compatible Galaxy phone and follow the on-screen guide to record an ECG; a successful reading confirms the sensor is functioning as intended.

Which accessories are included with the 40mm LTE model and what must I purchase separately?

The box contains the watch and a charging cable; a compatible Galaxy smartphone is required for setup and LTE service must be activated through your carrier.

Should I choose the 40mm LTE version or a non-LTE model for standalone calls and data?

Select the LTE version if you want to make calls, stream music, and receive notifications without your phone nearby; choose a non-LTE model only if you always carry your phone.
