I want to make a phone call in React Native, I am a beginner on react native so I came across this question which looks like mine => [How to make phone call in React Native?](https://stackoverflow.com/questions/51545064/how-to-make-phone-call-in-react-native/57056709)

So, this is a part of my code but it's not working, when I click on the icon, nothing is happening and I have no error on my terminal, it's very weird. This is my code:

```
import React from 'react';
import { Image, Text, View, StyleSheet } from 'react-native';

import { Avatar } from "react-native-elements";
import { Linking } from 'react-native';

export const makeCall = () => {

    let phoneNumber = '';

    if (Platform.OS === 'android') {
        phoneNumber = 'tel:${0123456789}';
    } else {
        phoneNumber = 'telprompt:${0123456789}';
    }

    Linking.openURL(phoneNumber);
};

const Contacts = () => {

  return (
    <View style={styles.column}>
       <Avatar
         size={65}
         rounded
         overlayContainerStyle={{ backgroundColor: '#fff' }}
         icon={{ name: 'phone', color: '#113D78', type: 'font-awesome' }}
         onPress={() => makeCall}
         style={{
           width: 65,
           height: 65,
           borderRadius: 50,
           borderWidth: 2,
           borderColor: '#113D78',
         }}
     />
     <Text style={styles.subtitle}>Phone</Text>
   </View>
);

```

}

export default Contacts;
