Getting an eSIM onto Your iPhone

Works with iPhone XS and newer — that covers the 11, 12, 13, 14, 15, 16, 17 and anything released after. Use these steps to scan your eSIM QR code and be online within 2 minutes.

Check these first: You need an eSIM-compatible iPhone (XS or later) that's not locked to a carrier. A Wi-Fi connection is required to pull down the eSIM profile.

Adding an eSIM to iPhone — The Full Process

1
Connect to Wi-Fi
Connect to Wi-Fi before you begin. The eSIM profile downloads over the internet, so you'll need a working connection.
2
Check your iPhone mail
Find the Onetel email carrying your QR code. Open it straight on your iPhone — skip the second device.
3
Press and hold the QR code
Press and hold your finger on the QR code image in the email. A menu appears — tap "Add eSIM". That's the quickest route on iPhone.
4
Alternative: use Settings
If the hold-down option stays hidden, go to Settings → Cellular → Add eSIM → Use QR Code and scan the code with your camera.
5
Label and activate
Tap Continue then Add Cellular Plan. Name it after your destination (e.g. "Japan trip"). Switch it on when you land.
Fastest route on iPhone

Open the Onetel email on your iPhone, then hold your finger on the QR code until a popup appears. Tap "Add eSIM" — finished in seconds, no Settings needed.

Tip

You can add the eSIM before your trip and switch it on when you land. Go to Settings → Cellular → your eSIM plan → toggle as needed.

eSIM iPhone Problems — What to Check

Open the email on your iPhone itself. If the code has expired, ask support to send a new one.

Your phone may be carrier-locked or not eSIM-compatible. Check Settings → General → About → EID — no EID means no eSIM support. If you have one, contact your carrier to unlock.

Turn on Data Roaming for your eSIM line. In Settings → Cellular → your eSIM, switch Data Roaming on.

Each eSIM profile is tied to the first device it was installed on. Contact support to get a new one issued.
