React Native Phone Calls

Here is an Example to Make a Phone Call in React Native App. To make a Phone Call from React Native App we will use react-native-phone-call. With the help of this example, You can provide one tab call feature to the users of your application.

How to Make a Phone Call in React Native?

const triggerCall = () => {
  // Check for perfect 10 digit length
  if (inputValue.length != 10) {
    alert('Please insert correct contact number');
    return;
  }

  const args = {
    number: inputValue,
    prompt: true,
  };
  // Make a call
  call(args).catch(console.error);
};

In this example of making a Call from React Native App, we will open the contact number on a click of a button in the dialer to call directly using a call(args) provided by react-native-phone-call. So let’s get started.

To Make a React Native App

Getting started with React Native will help you to know more about the way you can make a React Native project. We are going to use react native command line interface to make our React Native App.

If you have previously installed a global react-native-cli package, please remove it as it may cause unexpected issues:

npm uninstall -g react-native-cli @react-native-community/cli

Run the following commands to create a new React Native project

npx react-native init ProjectName

If you want to start a new project with a specific React Native version, you can use the --version argument:

npx react-native init ProjectName --version X.XX.X

Note If the above command is failing, you may have old version of react-native or react-native-cli installed globally on your pc. Try uninstalling the cli and run the cli using npx.

This will make a project structure with an index file named App.js in your project directory.

Installation of Dependency

To use call we have to install react-native-phone-call package.

To install this open the terminal and jump into your project

cd ProjectName

Run the following command

npm install react-native-phone-call --save

This command will copy all the dependencies into your node_module directory. –save is optional, it is just to update the react-native-phone-call dependency in your package.json file.

Code to Make a Phone Calls

Now Open App.js in any code editor and replace the code with the following code

App.js

// Example to Make a Phone Call in React Native App
// https://aboutreact.com/example-to-make-a-call-from-the-react-native-app/

// import React in our code
import React, {useState} from 'react';

// import all the components we are going to use
import {
  SafeAreaView,
  StyleSheet,
  View,
  Text,
  TouchableOpacity,
  TextInput,
} from 'react-native';

// import Call API
import call from 'react-native-phone-call';

const App = () => {
  const [inputValue, setInputValue] = useState('9999999999');

  const triggerCall = () => {
    // Check for perfect 10 digit length
    if (inputValue.length != 10) {
      alert('Please insert correct contact number');
      return;
    }

    const args = {
      number: inputValue,
      prompt: true,
    };
    // Make a call
    call(args).catch(console.error);
  };

  return (
    <SafeAreaView style={styles.container}>
      <View style={styles.container}>
        <Text style={styles.titleText}>
          Example to Make a Phone Call in React Native App
        </Text>
        <Text style={styles.titleTextsmall}>
          Enter Conatct Number to Call
        </Text>
        <TextInput
          value={inputValue}
          onChangeText={
            (inputValue) => setInputValue(inputValue)
          }
          placeholder={'Enter Conatct Number to Call'}
          keyboardType="numeric"
          style={styles.textInput}
        />
        <TouchableOpacity
          activeOpacity={0.7}
          style={styles.buttonStyle}
          onPress={triggerCall}>
          <Text style={styles.buttonTextStyle}>
            Make a Call
          </Text>
        </TouchableOpacity>
      </View>
    </SafeAreaView>
  );
};

export default App;

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: 'white',
    padding: 10,
    textAlign: 'center',
  },
  titleText: {
    fontSize: 22,
    textAlign: 'center',
    fontWeight: 'bold',
  },
  titleTextsmall: {
    marginVertical: 8,
    fontSize: 16,
  },
  buttonStyle: {
    justifyContent: 'center',
    marginTop: 15,
    padding: 10,
    backgroundColor: '#8ad24e',
  },
  buttonTextStyle: {
    color: '#fff',
    textAlign: 'center',
  },
  textInput: {
    height: 40,
    borderColor: 'gray',
    borderWidth: 1,
    width: '100%',
    paddingHorizontal: 10,
  },
});

Known Issue for iOS

This example will not work with IOS simulator as simulator do not provide the phone call facility in case you try to run on the simulator you will get “invalid URL provided: tel:XXXXXXXXXX”.

Error while running this example on IOS simulator

To Run the React Native App

Open the terminal again and jump into your project using.

cd ProjectName

1. Start Metro Bundler

First, you will need to start Metro, the JavaScript bundler that ships with React Native. To start Metro bundler run following command

npx react-native start

Once you start Metro Bundler it will run forever on your terminal until you close it. Let Metro Bundler run in its own terminal. Open a new terminal and run the application.

2. Start React Native Application

To run the project on an Android Virtual Device or on real debugging device

npx react-native run-android

or on the iOS Simulator by running (macOS only)

npx react-native run-ios

FAQ:
1. How to call without having to press the call button?
2. How can I call directly from my react native application without opening the Dialler?
Ans: Sorry but this is not possible with this example. This is a cross platform example which does not provide the same. If you need that in any case then you can see react-native-immediate-phone-call, with that library no additional user input is required for Android and the call starts instantly (Apple always asks confirmation since the last iOS updates…)
