Installing an eSIM (One UI)
Preparation
- Carrier-unlocked phone — check in Settings
- A Wi-Fi connection is needed
- Update One UI to the latest version
With a QR code
- Open: Settings → Connections → SIM manager
- Tap: Add eSIM
- Choose: Scan carrier QR code
- Scan the QR code with the camera
- Confirm the installation
- Wait for the profile to download
- Name the profile
Manual installation
If the QR code doesn't work:
- Settings → Connections → SIM manager → Add eSIM
- Tap: Enter activation code
- Enter the SM-DP+ address and the activation code
Dual SIM settings (One UI)
After installation, One UI asks you to set the SIMs' roles:
Mobile data
Settings → Connections → SIM manager → Mobile data → select the eSIM
Calls and texts
Settings → Connections → SIM manager → Calls / Messages → select the physical SIM (home number)
Turning on data roaming
Settings → Connections → Mobile networks → select the eSIM profile → Data roaming: On
Important: Turn data roaming off for the physical SIM!
Galaxy Z Fold / Z Flip special notes
On the foldable Samsung models, setup works the same way as on the S series. A few tips:
- On the Z Fold you can access the SIM manager from the external display too
- On the Z Flip the cover display doesn't show SIM management — set it up on the inner display
- All the foldable models support dual SIM (physical + eSIM)
Troubleshooting
The 'Add eSIM' option doesn't appear
- Check the model number: not supported in every region
- Update One UI
- Dial *#06# — if there's no EID line, your phone isn't eSIM-capable
The QR code won't scan
- Increase the screen brightness on the device showing the QR code
- Try holding it closer/further away
- Use manual entry (SM-DP+ address + activation code)
No internet in the destination
- Check that the eSIM is selected as your data connection
- Turn on data roaming for the eSIM profile
- Restart your phone
- Check that the phone is connected to the destination's network: Settings → Connections → Mobile networks → Network operator
Summary
Setting up an eSIM on Samsung Galaxy phones is simple: Settings → Connections → SIM manager → Add eSIM → scan QR code. The most important thing: select the eSIM as your mobile data connection and turn on data roaming. The whole process takes 2–3 minutes.
