# Enable Direct Installation

A direct installation allows users to install an eSIM on their Android device without a QR code. It provides the smoothest experience for installing an eSIM.

1. Request the **Direct Installation** at Gigastore and follow the process
2. Once approved, proceed with the technical integration

## Prepare SHA-1

To use the Gigastore Android SDK in your app, you need to provide the certificate fingerprint of your app to DENT.

If your app is **self-signed**, identify the SHA-1 using `keytool` following [Google documentation](https://developers.google.com/android/guides/client-auth).

If you are using **Play App Signing**, provide the bundle SHA-1 from the [Google Play Console](https://play.google.com/console/developers/app/keymanagement).

{% hint style="info" %}
**App Bundles** might have a different signature in Google Play than during testing the APK locally. In this case, change your App Bundle signature to your self-signed key (see this [link](https://support.google.com/googleplay/android-developer/answer/9842756?hl=en#zippy=%2Cdescriptions-of-keys-artifacts-and-tools%2Capp-signing-key-requirements)) or provide both SHA-1 fingerprints to Gigastore.
{% endhint %}

## Request Direct Installation

Once you identified the correct fingerprint, send us your SHA-1 via [this form.](https://survey.typeform.com/to/MT8yktD2)

Registering your app might take some days. We will send you an email once your app has been registered. Schedule enough time to get the signature processed.
