⚠️ Required Setup for Users

This plugin will not work without the following setup in your app.

1. Privileged Permission Warning

⚠️ To use this plugin, you must sign your eSIMs from the eUICC/carrier with your package name or SHA-1 keys.

The permission:

android.permission.WRITE_EMBEDDED_SUBSCRIPTIONS

is signature/privileged. Your app will not be allowed to install eSIMs unless:

• It is a system/privileged app signed with the platform key, or
• It has carrier privileges granted by the eUICC/carrier.

If you do not meet these conditions, the plugin will return:

error:PERMISSION_DENIED

and installation will not proceed.

---

2. AndroidManifest.xml changes

In your app’s android/app/src/main/AndroidManifest.xml:

• Add the tools namespace to the <manifest> tag if not already present:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    package="com.example.app">

• Add protected eSIM write permission:

<uses-permission
    android:name="android.permission.WRITE_EMBEDDED_SUBSCRIPTIONS"
    tools:ignore="ProtectedPermissions" />

• Declare and request your app-specific broadcast permission:

<!-- Declare a custom signature-level permission the LPA expects your app to own -->
<permission
    android:name="com.your_package_name.lpa.permission.BROADCAST"
    android:protectionLevel="signature" />

<!-- Request/Use that permission in your own app -->
<uses-permission android:name="com.your_package_name.lpa.permission.BROADCAST" />

⚠️ Replace every com.your_package_name with your actual applicationId from build.gradle.

• (Optional but recommended) Add telephony feature declarations:

<uses-feature android:name="android.hardware.telephony" android:required="false" />
<uses-feature android:name="android.hardware.telephony.euicc" android:required="false" />

2. Gradle minimum SDK

    minSdkVersion 28
  }
  compileSdkVersion 35
  targetSdkVersion 35
}
