Steps
Confirm with your carrier that your line supports eSIM, then ask for the eSIM QR code or activation details. Save or print the code before you start.
Open Settings and tap Cellular. On some regions this menu is called Mobile Service or Mobile Data.
Tap Add eSIM. If you are moving a number from an old phone, choose Transfer from Nearby iPhone and follow the prompts on both devices.
To add a new line, tap Use QR Code. The rear camera opens inside Settings.
Hold the phone steady over the carrier QR code until the whole square sits inside the frame. Tap Continue when the eSIM details appear.
For the second method, close Settings and open the Camera app instead. Point it at the QR code and tap the yellow eSIM banner that pops up.
Give the new line a label such as Travel or Work, then pick which line handles calls, messages and mobile data by default.
Leave the phone on Wi-Fi and wait while it activates. This usually takes a few minutes, and the signal bars appear when the line is live.
Test the line by making a call or sending a text. Once it works, you can delete the old SIM or eSIM from Settings, Cellular.
Tips and common mistakes
Keep the eSIM QR code handy, since most carriers issue single-use codes and you may need a fresh one if activation fails.
Do not delete your old eSIM until the new line is confirmed working, or you may lose your number temporarily.
Stay on Wi-Fi during activation and restart the phone if the line shows No Service after ten minutes.
Turn the phone off and on again if the Camera app does not show the eSIM banner when you scan the code.
Questions
How long does eSIM activation take?
Most lines activate within a few minutes once the QR code is scanned. Some carriers take up to a few hours, so contact them if nothing happens after that.
Can I use two eSIMs at once on the iPhone 18 Pro?
Yes. You can store several eSIMs on the phone and keep two lines active together, then choose which one handles data and which handles calls.
What if I lost the carrier QR code?
Ask your carrier to resend the eSIM activation code or check your account page in their app. Most will issue a new code free of charge.
