How can I send a text from my React Native App without leaving my app? - react-native

Question

I have a React Native - Expo Android mobile app that we are using to send text messages out to customers to let them know when we arrive, currently using Twilio and it is expensive, I have tried many code examples to send a text message directly from the phone and they all seem to go outside the app and want to send the text message through the phone's default message app eg Messages, we want to stay in our app and send them.
My question is:
Is there a way to do this? If so how?
If not what is a cheaper solution than Twilio to send texts that will work in a React Native - Expo app?
I have been trying to find a solution now for quite awhile.
Thanks in advance for your help!
I have tried many code examples with no luck, here is an example of the code I have tried:
Here is an example of the code I am trying:
/** #format */
import { StatusBar } from "expo-status-bar";
import { StyleSheet, Text, View } from "react-native";
import { Entypo } from "#expo/vector-icons";
import Communications from "react-native-communications";
export default function App() {
return (
<View style={styles.container}>
<Text style={styles.textStyle}>SmS App</Text>
<Entypo
name="message"
size={70}
color="#202668"
onPress={() => Communications.text(
'3435447131',
'Hello'
)}
/>
<StatusBar style="auto" />
</View>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: "#fff",
alignItems: "center",
justifyContent: "center",
},
textStyle: {
fontWeight: "bold",
fontSize: 30,
color: "#2AB4F3",
bottom: 10,
},
});
