How to install an eSIM on iPhone
4 min read
Before installing, confirm that your exact iPhone model and region support eSIM and that it is carrier-unlocked. Connect to Wi-Fi and have the QR code from your delivery email or private tracking page ready. Check the plan's activation rules first.
Installation steps
- 1
Open the QR code on another screen
Display the QR from your order email on a laptop, tablet or second phone so you can scan it with your iPhone's camera.
- 2
Go to Settings → Cellular → Add eSIM
Choose 'Use QR Code', point the camera at the code, and follow the on-screen prompts.
- 3
Label the new line
Name it 'Travel' so it's easy to tell apart from your main line. Keep your primary line as default for calls and iMessage.
- 4
Set the eSIM as your data line
Under Cellular Data, select the new Travel line. Leave 'Allow Cellular Data Switching' off to avoid accidental roaming on your home SIM.
- 5
Enable Data Roaming on the eSIM
On the Travel line, enable Data Roaming if the plan's instructions require it. Keep your home line's data roaming off unless you intend to use that carrier's roaming service.
When to install and activate
Install the profile at home on Wi-Fi — the plan's validity usually starts when the eSIM first connects to a network at your destination, not at installation. Check your plan details if unsure.
Common issues
- 'No service' on landing: toggle Airplane Mode for 10 seconds, then manually select a network under Network Selection.
- QR won't scan: use the manual activation code from your order page under 'Enter Details Manually'.
- Profile won't install: confirm the iPhone is carrier-unlocked — Settings → General → About → Carrier Lock should read 'No SIM restrictions'.
- Data very slow: LTE/5G selection can take a few minutes on first connect; try toggling Voice & Data to LTE and back to 5G Auto.
