Before you start
Connect to Wi-Fi, and have your delivery page open — it holds your install link and QR code. Your iPhone needs to be eSIM-capable (XS / XR or newer) and unlocked.
The steps
- On your delivery page, tap the install link — on most iPhones that's the whole job. Or do it by hand:
- Open Settings → Cellular (called Mobile Data in some regions) → Add eSIM.
- Choose Use QR Code and scan the QR code on your delivery page. No second screen handy? Tap Enter Details Manually and paste the activation code from the same page.
- Label the line StateLine so you always know which is which, and continue through the prompts.
- Turn the StateLine line On, and switch Data Roaming ON for it under Settings → Cellular → StateLine.
- 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.
