# 6. Change Language

Use the following to change the TyrAds SDK language and update its internal locale settings:

```csharp
TyrSDKPlugin.Instance.SetLanguage("en");
```

#### Parameters:

* `languageCode` (string): A string representing the desired language code (e.g., "en" for English, "es" for Spanish). This should be a valid ISO 639-1 language code. \
  Supported languages: English (en), Spanish (es), Indonesian (id), Japanese (ja), Korean (ko), Chinese Simplified (zh-Hans-CN).

#### Notes:

* By default, the TyrAds SDK uses the device’s system language.
* This method saves the selected language in shared preferences so it persists across sessions.
* Ensure your app and the TyrAds SDK support the provided language code; otherwise, English will be used.
