# Install eSIM

### Direct Installation

The `installProfile` method can be used to install an eSIM profile on a user's device. The device operating system will show up an installation wizard for the user.

```
let profile = <use activateInventory method>
Gigastore.installProfile(profile: profile,
                      completion: { (profile, error) in
    print("profile: \(profile)")
    print("error: \(error)")
})
```

This function returns either the installed profile or an error object containing the error.

### QR Code Installation

Due to restrictions, **Direct Installation** might not be available for some apps.&#x20;

In this case, you can use the iOS QR code feature.&#x20;

First, generate a QR code based on the `activationCode` of the `profile` object. Several libraries generate QR codes on iOS. Ensure you generate a QR code with a valid activation code starting with *LPA$*.

Then, provide the QR code to the user via email or as an image in your app that can be saved to photos.

Please add a proper UX to explain to your users how to install the eSIM profile.

Check our [eSIM Profiles](/api/esim-profiles.md) section of our API if you want to initiate this process from your app middleware.
