How do I send a text message?

To send a test text message using SNS, here are the basic steps:

1. First, you need to create an Amazon SNS topic that delivers messages via SMS. In the SNS console, go to Topics and create a new Standard type topic - Create topic

2. Create an SNS subscription to that topic using the SMS protocol. Enter a phone number that can receive texts. Make sure the number includes country code and area code without any other characters - Create subscription

3. You can now test the SMS notification by sending a test message from the SNS console. The subscribed phone will receive the test text.

Or

To send messages programmatically, you can publish to the SNS topic using the Publish API or SDKs. The message will be delivered as a text to the subscribed number. For more information, click here Publish API
