How to Set Up eSIM on iPhone: A Complete Walkthrough
Learn how to activate an eSIM on your iPhone in minutes. From QR codes to manual entry and transferring from another iPhone — we cover every method for iOS.
Key takeaways
- iPhone compatibility: iPhone XS, XR, SE (2nd gen) and newer support eSIM (US models 14–16 are eSIM-only).
- Three installation methods: Scan QR code (most common), tap an install link, or transfer from another iPhone.
- Configuration: Label your eSIM, set it as default for data, keep your primary line for calls/SMS.
- Activation: Install before departure; the eSIM activates automatically when you arrive at your destination.
iPhones that support eSIM
Compatibility
What you'll need before you start
- An eSIM plan from eSimTrip or another provider (purchased and ready to activate)
- A stable Wi-Fi connection during setup
- Your iPhone unlocked and updated to the latest iOS version
- The QR code or activation details sent to your email
Method 1: Scan a QR code (most common)
This is the standard way most eSIM providers, including eSimTrip, deliver plans. Follow these steps:
- Open Settings → Cellular (or Mobile Service).
- Tap Add eSIM or Add Cellular Plan.
- Tap Use QR Code and scan the code sent by your provider.
- If prompted, enter the confirmation code (usually 4–6 digits provided with your plan).
- Tap Add Cellular Plan to complete installation.
Method 2: Install via eSimTrip app or link
Many modern eSIM providers, including eSimTrip, offer direct installation links. If you purchased through our app or website on your iPhone, you can often tap an “Install eSIM” button that automatically opens Settings and adds the plan — no QR code required. This is the fastest method when available.
- Check your confirmation email for an installation link.
- Tap the link directly on your iPhone (must be the same device you plan to use).
- Follow the on-screen prompts to confirm the installation.
Method 3: Transfer eSIM from another iPhone
If you're upgrading to a new iPhone and your carrier supports eSIM transfer, you can move your plan without contacting support. Both devices must be running iOS 16 or later and signed into the same Apple ID with two-factor authentication enabled.
- On your old iPhone: Go to Settings → Cellular → tap the eSIM you want to transfer.
- Tap Transfer to New iPhone and follow instructions.
- On your new iPhone: When prompted, confirm the transfer request.
- Wait for the plan to appear on your new device (may take a minute or two).
Labeling and configuring your eSIM
After adding an eSIM, iOS will ask you to assign a label. Choose something descriptive like “Travel Data” or “eSimTrip USA”. This helps you identify the line later.
You can also set default lines for cellular data, calls, and messages. For travel eSIMs (data-only plans), we recommend:
- Cellular Data: Your travel eSIM
- Default Voice Line: Your primary number (if you want to keep receiving calls)
- Allow Cellular Data Switching: Off (to avoid unexpected roaming charges)
Activating your eSIM at your destination
Most travel eSIMs activate when they first connect to a supported local network in your destination country. You can install the profile before departure, but data won't start until you arrive.
Before departure
After arrival
Troubleshooting common issues
- "Cellular plan cannot be added" — Restart your iPhone and try scanning again. Ensure your device isn't carrier-locked.
- No service after arrival — Toggle Airplane Mode on/off, or manually select a network in Settings → Cellular → Network Selection.
- QR code not working — Request manual entry details (SM-DP+ and activation code) from your provider.
- eSIM disappeared after iOS update — Go to Settings → Cellular → Add eSIM → the plan may reappear under "Previous eSIMs."
Removing or resetting an eSIM
When your travel plan expires or you no longer need it, you can remove the eSIM from your iPhone:
- Go to Settings → Cellular.
- Tap the eSIM you want to remove.
- Scroll down and tap Remove Cellular Plan.
- Confirm removal. The eSIM profile will be deleted from your device.
