Example to Send Text SMS on Button Click in React Native

Introduction

Here is an Example to Send Text SMS on Button Click in React Native. Instead of remembering or copying the number to send the Text SMS you can provide one tab send SMS experience to the users of your application.

We will use react-native-sms package for this example.

To Send SMS

SendSMS.send(
  {
    // Message body
    body: bodySMS,
    // Recipients Number
    recipients: [mobileNumber],
    // An array of types 
    // "completed" response when using android
    successTypes: ['sent', 'queued'],
  },
  (completed, cancelled, error) => {
    if (completed) {
      console.log('SMS Sent Completed');
    } else if (cancelled) {
      console.log('SMS Sent Cancelled');
    } else if (error) {
      console.log('Some error occured');
    }
  },
);

In this example of sending a Text SMS from React Native App, we will send the SMS by clicking on a button using  react-native-sms library. 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 SendSMS we need to install react-native-sms package. To install this

Open the terminal and jump into your project

cd ProjectName

Run the following command

npm install react-native-sms --save

This command will copy all the dependencies into your node_module directory.

CocoaPods Installation

Please use the following command to install CocoaPods

npx pod-install

Permission to Send SMS for Android

We are trying to use the SMS feature so we need to add some permission in AndroidManifest.xml file for Android. For more about the permission, you can see this post.

So we are going to add the following permissions in the AndroidMnifest.xml

<uses-permission android:name="android.permission.READ_SMS"/>

Here we have done all the configurations we need.

Code to Send Text SMS

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

App.js

// Example to Send Text SMS on Button Click in React Native
// https://aboutreact.com/send-text-sms-in-react-native/

// 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 SMS API
import SendSMS from 'react-native-sms';

const App = () => {
  const [mobileNumber, setMobileNumber] = useState('9999999999');
  const [bodySMS, setBodySMS] = useState(
    'Please follow https://aboutreact.com',
  );

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

    SendSMS.send(
      {
        // Message body
        body: bodySMS,
        // Recipients Number
        recipients: [mobileNumber],
        // An array of types 
        // "completed" response when using android
        successTypes: ['sent', 'queued'],
      },
      (completed, cancelled, error) => {
        if (completed) {
          console.log('SMS Sent Completed');
        } else if (cancelled) {
          console.log('SMS Sent Cancelled');
        } else if (error) {
          console.log('Some error occured');
        }
      },
    );
  };

  return (
    <SafeAreaView style={styles.container}>
      <View style={styles.container}>
        <Text style={styles.titleText}>
          Example to Send Text SMS on Button Click in React Native
        </Text>
        <Text style={styles.titleTextsmall}>
          Enter Mobile Number
        </Text>
        <TextInput
          value={mobileNumber}
          onChangeText={
            (mobileNumber) => setMobileNumber(mobileNumber)
          }
          placeholder={'Enter Conatct Number to Call'}
          keyboardType="numeric"
          style={styles.textInput}
        />
        <Text style={styles.titleTextsmall}>
          Enter SMS body
        </Text>
        <TextInput
          value={bodySMS}
          onChangeText={(bodySMS) => setBodySMS(bodySMS)}
          placeholder={'Enter SMS body'}
          style={styles.textInput}
        />
        <TouchableOpacity
          activeOpacity={0.7}
          style={styles.buttonStyle}
          onPress={initiateSMS}>
          <Text style={styles.buttonTextStyle}>
            Send Message
          </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,
  },
});

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
