That QR code in your confirmation email is the key to your eSIM. Here is exactly what it does.
When you buy an eSIM, you receive a QR code. It is not the plan itself — it is a shortcut that tells your phone where to download the plan.
What happens when you scan
Your phone reads the QR code, contacts the provider's server, and downloads your eSIM profile. Within seconds, the plan appears in your settings.
Installing from the code
- Open your phone's Add eSIM / Add Cellular Plan screen.
- Choose "Use QR Code" and scan it.
- Confirm and label the plan.
No camera handy?
You can also enter the details manually using the SM-DP+ address and activation code included with your plan.
Keep your QR code safe until installed — some can only be used once.
