SMS

expo-sms provides access to the system's UI/app for sending SMS messages.

Platform Compatibility

Android Device	Android Emulator	iOS Device	iOS Simulator	Web

Installation

expo install expo-sms

If you're installing this in a bare React Native app, you should also follow these additional installation instructions.

API

import * as SMS from 'expo-sms';

`SMS.isAvailableAsync()`

Determines whether SMS is available.

Returns

Returns a promise that resolves to a Boolean, indicating whether SMS is available on this device.

Example

const isAvailable = await SMS.isAvailableAsync();
if (isAvailable) {
  // do your SMS stuff here
} else {
  // misfortune... there's no SMS available on this device
}

`SMS.sendSMSAsync(addresses, message)`

Opens the default UI/app for sending SMS messages with prefilled addresses and message.

Arguments

addresses (Array\<string>|string) -- An array of addresses (phone numbers) or single address passed as strings. Those would appear as recipients of the prepared message.
message (string) -- Message to be sent

Returns

Returns a Promise that resolves when the SMS action is invoked by the user, with corresponding result:

If the user cancelled the SMS sending process: { result: 'cancelled' }.
If the user has sent/scheduled message for sending: { result: 'sent' }.
If the status of the SMS message cannot be determined: { result: 'unknown' }.

Android does not provide information about the status of the SMS message, so on Android devices the Promise will always resolve with { result: 'unknown' }.

Note: The only feedback collected by this module is whether any message has been sent. That means we do not check actual content of message nor recipients list.

Example

const { result } = await SMS.sendSMSAsync(
  ['0123456789', '9876543210'],
  'My sample HelloWorld message'
);
