From the Galaxy Wearable app on your paired device, tap Watch Settings.
To be able to set up a mobile plan for your Galaxy Watch, your paired device needs to have an eSIM or physical SIM card installed.
Scroll to Mobile plans.
Tap Mobile plans.
After this step, the Wearable app will begin searching for a cellular plan to apply to your watch. If your carrier provided a QR code or other setup instructions, you may need to have those ready before proceeding.
You've completed the steps!
