Before you start
Connect to Wi-Fi, and have your delivery page open — it holds your QR code. Your Galaxy needs to be an eSIM model (most S20 and newer, Note 20, Z Fold / Z Flip) and unlocked. Menu names vary slightly by model and region.
The steps
- Open Settings → Connections → SIM manager.
- Tap Add eSIM → Scan QR code, and scan the QR code on your delivery page. (On some models: Add mobile plan.)
- Confirm the plan details and tap Add.
- In SIM manager, turn the new line On, and set Roaming on for it.
- Give it a minute to find a network. Your +1 number appears on your delivery page and in your dashboard the first time the line connects — and your plan's days start counting from that moment, not from purchase.
Careful
Install on the phone you'll actually use. If you delete the eSIM profile afterwards, it can't be brought back — a replacement means a new line and a new number.
