How to install an eSIM on iPhone
It takes about two minutes. Install over Wi‑Fi before you fly, then switch the travel line on when you land.
Before you start
- You need an iPhone XS, XS Max, XR or newer, and it must be unlocked. Check in Settings › General › About › Carrier Lock: it should say “No SIM restrictions”.
- Connect to Wi‑Fi. Your iPhone needs internet to download the eSIM.
- Keep the email with your QR code open on another screen (a laptop, tablet or printed copy), or use option B below.
Option A: scan the QR code
- Open Settings › Cellular (called Mobile Data in some countries).
- Tap Add eSIM (or Add Cellular Plan), then Use QR Code.
- Scan the QR code from your email and tap Continue. Stay on this screen until it finishes. It can take a few minutes.
- When asked, label the new line, for example “Travel”.
Option B: the QR code is on the same iPhone
On iOS 17.4 or later, open the email in the Mail app, press and hold the QR code, then tap Add eSIM. You can also save the QR code to Photos and choose it from the Use QR Code screen.
Option C: enter the details manually
Go to Settings › Cellular › Add eSIM › Use QR Code › Enter Details Manually and type the SM‑DP+ address and activation code from your installation instructions.
When you land
- Go to Settings › Cellular, tap your travel line and make sure Turn On This Line is on.
- Under Settings › Cellular › Cellular Data, choose the travel line.
- Turn on Data Roaming for the travel line, unless your installation instructions say otherwise.
Your home SIM stays in your phone, so you can still receive calls and SMS on your usual number. To avoid roaming charges from your home carrier, you can turn off data roaming for your home line.
No internet? Try this
- Check that the travel line is on, selected for Cellular Data, and that Data Roaming is on for it.
- If your installation instructions list an APN, enter it in Settings › Cellular › [travel line] › Cellular Data Network.
- Turn Airplane Mode on for 15 seconds, then off. Or restart your iPhone.
- Don’t delete the eSIM. A deleted eSIM usually can’t be reinstalled.
Menu names can differ slightly by phone brand and software version.
Find an eSIM for your tripFAQ
Can I install the eSIM before I travel?
Yes. For most plans the days start counting when the eSIM first connects to a supported network at your destination, so installing a few days early is fine. Check your plan details to be sure.
Can I use the eSIM for a personal hotspot?
Yes, as long as your iPhone and the local network support it.
Does my iPhone support eSIM?
iPhone XS, XS Max, XR and newer support eSIM. iPhones bought in mainland China, Hong Kong or Macao may not.
