Install Your eSIM
Follow these steps to get online in under 2 minutes. Before you begin, make sure you're connected to Wi-Fi.
Before you start: Your iPhone needs to be eSIM-compatible (iPhone XS or later) and carrier-unlocked. You'll also need a Wi-Fi connection.
1
Connect to Wi-Fi
Connect to Wi-Fi first. The eSIM profile needs internet to download.
2
Open the email on your iPhone
Find the Onetel email containing your QR code. Open it straight on your iPhone — skip the second device.
3
Press and hold the QR code image
Press and hold your finger on the QR code image in the email. A menu appears — tap "Add eSIM". This is the fastest route on iPhone.
4
Alternative: use Settings
If the hold-down option doesn't show, go to Settings → Cellular → Add eSIM → Use QR Code and scan with your camera.
5
Scan the QR code
With the Settings method, point your iPhone camera at the QR code. Your iPhone picks it up automatically.
6
Activate & label
Tap Continue, then Add Cellular Plan. Name it for your destination (e.g. "Japan trip"). That's it!
Fastest on iPhone
Open the Onetel email on your iPhone, then press and hold the QR code until a popup appears. Tap "Add eSIM" — finished in seconds, no need to open Settings.
Tip
You can install the eSIM before you travel and switch it on when you land. Go to Settings → Cellular → your eSIM plan → toggle it on/off as needed.
Troubleshooting
Check that you\'re scanning the QR code from another device or a printed copy. If the code has expired, contact support for a replacement.
Your handset might be carrier-locked. Ask your carrier to unlock it, or look in Settings under Cellular to see if an eSIM option appears.
Turn on Data Roaming for your eSIM line. Settings → Cellular → your eSIM → switch Data Roaming on.
An eSIM profile is tied to the first device it was installed on. Get in touch with support and we'll sort a replacement.
