How to Install an eSIM Using a QR Code on Android

This page provides step-by-step instructions for installing an eSIM on an Android device using a QR code.
It covers the standard Android 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 your Android device 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 Android device.

The profile contains the information required for the device to connect to mobile networks.

Standard Android QR Code Installation Steps

  1. Open the Settings app.
  2. Tap Network & Internet or Connections.
  3. Select SIMs, SIM Manager, or Mobile Network.
  4. Tap Add eSIM or Add mobile plan.
  5. Choose the option to scan a QR code.
  6. Scan the QR code when prompted.
  7. Follow on-screen prompts to complete installation.

Menu names may vary slightly by Android version and device manufacturer.

During Installation

While the QR code is being processed, the device may display messages such as “Downloading SIM” or “Activating.”

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 eSIM profile first, followed by a separate activation or confirmation step.

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 in the SIM list within network 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.
