There are two ways you can activate your Samsung Galaxy Watch and Galaxy Watch Active2:
- As a standalone device with its own mobile number on a standard plan (not available for prepaid). You can send and receive calls and text messages from your Samsung Galaxy Watch without pairing it to a smartphone. To activate the Samsung Galaxy Watch on its own, you'll need to download the Galaxy Wearable app on an Android or iOS smartphone. Download the Galaxy Wearable app from Google Play or the Apple App Store.
- Pair it with a compatible Android or iOS "host" smartphone on a NumberShare plan. NumberShare is a service that lets you use your mobile number on up to 5 connected devices. You can send and receive calls and messages on whatever device is at hand, even if you're away from your phone. Visit our NumberShare FAQs to learn more.
