This article describes how you can use the .NET Multi-platform App UI (.NET MAUI) IPhoneDialer interface. This interface enables an application to open a phone number in the dialer.

The default implementation of the IPhoneDialer interface is available through the PhoneDialer.Default property. Both the IPhoneDialer interface and PhoneDialer class are contained in the Microsoft.Maui.ApplicationModel.Communication namespace.

Get started

To access the phone dialer functionality, the following platform-specific setup is required.

If your project's Target Android version is set to Android 11 (R API 30) or higher, you must update your Android Manifest with queries that use Android's package visibility requirements.

In the Platforms/Android/AndroidManifest.xml file, add the following queries/intent nodes in the manifest node:

<queries>
  <intent>
    <action android:name="android.intent.action.DIAL" />
    <data android:scheme="tel"/>
  </intent>
</queries>

Open the phone dialer

The phone dialer functionality works by calling the Open method with a phone number. When the phone dialer is opened, .NET MAUI will automatically attempt to format the number based on the country code, if specified.

if (PhoneDialer.Default.IsSupported)
    PhoneDialer.Default.Open("000-000-0000");
