Samsung Galaxy Watch Active2 eSIM Compatibility

The Samsung Galaxy Watch Active2 is a Samsung smartwatch with built-in eSIM support.

Samsung's eSIM implementation integrates smoothly with One UI, Samsung's Android skin. The SIM Manager in Settings gives you a clear overview of all installed SIMs, their status, and which is the default for calls and data. Samsung also supports eSIM transfer between Galaxy devices on One UI 5.0+, meaning you can move your eSIM profile to a new Galaxy phone without contacting your carrier.

DevRoute can automatically detect if a visitor is using Samsung Galaxy Watch Active2 and trigger eSIM-compatible flows instantly — no manual selection required.

1. Get your eSIM QR code or activation code from your carrier — most carriers send it via email, app, or SMS the moment you purchase a plan
2. On your Samsung device, open Settings and go to Connections (or Network & Internet on newer One UI versions)
3. Tap SIM Manager or SIM & Network
4. Select Add eSIM and then Scan QR Code
5. Point your camera at the QR code. If the QR code is damaged or won't scan, tap Enter Manually and type in the SM-DP+ address and activation code
6. Label your new line (e.g., "Travel" or "Work") and assign it as your default for calls, messages, or data

Samsung Galaxy devices with eSIM support include the S20 series and later, Z Fold and Z Flip foldables, and select A-series models. Note that carrier-locked variants may only accept eSIM from the original carrier.

If you have a Samsung Galaxy bought from a carrier (AT&T, Verizon, T-Mobile), it may be carrier-lock restricted and won't accept eSIM plans from other carriers. Unlocked international models (sold directly by Samsung) work with any GSMA-compliant carrier.

Samsung Galaxy Watch models with LTE support include eSIM capability, allowing the watch to connect to cellular networks independently of your phone. This means you can take calls, stream music, and use data on the go — even when your phone is at home. Most carriers that support smartwatch eSIM offer a monthly "Number Share" add-on for $5–$15.

With eSIM on your Samsung Galaxy Watch Active2, you can take calls, stream music, and use maps without your phone nearby. Most carriers offer a connected smartwatch plan starting at $5–$15/month that shares your existing phone number with the watch.
