How to Install an eSIM Using a QR Code on iPhone
This page provides step-by-step instructions for installing an eSIM on an iPhone using a QR code.
It covers the standard iOS installation flow and required conditions, without comparing providers or explaining eSIM concepts.
This page exists to guide installation actions only, not to troubleshoot activation failures or recommend connectivity options.
Before You Start
Before installing an eSIM using a QR code, ensure the iPhone supports eSIM and is connected to a stable internet connection.
The QR code must be accessible on another device or printed, as it cannot be scanned from the same screen.
What the QR Code Installation Does
Scanning a QR code downloads and installs an eSIM profile onto the iPhone.
The profile contains the information required for the device to connect to mobile networks.
Standard iPhone QR Code Installation Steps
- Open the Settings app.
- Tap Cellular or Mobile Data.
- Select Add eSIM.
- Choose Use QR Code.
- Scan the QR code when prompted.
- Follow the on-screen prompts to complete installation.
During Installation
While the QR code is being processed, the iPhone may display messages such as “Activating” or “Setting up cellular plan.”
This step can take several minutes depending on network conditions.
Two-Step Installation Note
Some eSIMs are engineered with a two-step installation process.
In these cases, scanning the QR code installs the profile first, followed by a separate activation or confirmation step within the device settings.
Koala Sim eSIMs are designed to follow a clear installation process whereby installation is done by scanning the QR code and activation is completed automatically once the esim connects to its destination network, making the installation processes distinct and easy to complete.
After Installation Completes
Once installed, the eSIM will appear as a new line under Cellular settings.
The eSIM can then be enabled, labelled, and selected for mobile data as required.
What Installation Does Not Do
- It does not remove an existing physical SIM.
- It does not automatically select the eSIM for mobile data.
- It does not delete apps or stored data.
