How to Install an eSIM on iPhone: Step-by-Step Guide

Installing an eSIM on iPhone takes under 2 minutes. Here's the complete process.

Before you start

Step-by-step installation

Step 1: Open Settings

Go to Settings → Cellular (or Mobile Data on some regions)

Step 2: Add eSIM

Tap "Add eSIM" or "Add Cellular Plan"

Step 3: Scan QR Code

Select "Use QR Code" and point your camera at the QR code from your provider. If you're setting up on the same device you received the email on, tap "Enter Details Manually" and copy-paste the activation code.

Step 4: Confirm

Tap "Add Cellular Plan" on the confirmation screen. Your eSIM is now installed.

Step 5: Set as travel line

Your phone will ask which line to use for data. Select your new eSIM for travel data. Keep your home SIM as your primary number for calls.

Step 6: Enable Data Roaming

Go to Settings → Cellular → your new eSIM → enable "Data Roaming". This is required for the eSIM to work abroad.

Activation timing

Most plans activate on first use. If you buy before travel, the plan clock usually starts when you first connect to a local network — not when you install the eSIM. Check your provider's terms.

Troubleshooting

**eSIM not connecting**: Toggle airplane mode off and on. If still not working, go to Settings → Cellular → your eSIM → toggle it off and on.

**"Invalid QR code" error**: QR codes can only be scanned once. If you've already scanned it, contact your provider for a replacement.

**No service after landing**: Make sure Data Roaming is enabled for your eSIM line. Some iPhones default this to off.
