Test your SMS Application
If you'd like to test API requests to send SMS messages without charging your account or actually sending an SMS, you can use your test credentials.
You use these credentials in the same way as your live credentials. However, when you authenticate with your test credentials, we will not charge your account, update the state of your account, or connect to real phone numbers.
To protect your production data, your test credentials can't interact with the data in your real account. As a consequence, you can't use phone numbers from your real account as the 'From' number in requests made with your test credentials.
Simulate a successful message by sending an SMS using the magic number +15005550006 as the From number, and a regular phone number for the To number.

You can simulate an attempt to send a message to a non-mobile number. Trigger this by passing the magic number +15005550009 as the To number.
