# SMS

> Send and receive SMS directly from a conversation thread.

SMS messages appear in the same thread as calls, in order, so you have the full contact history in one view.

## Sending a message

Open a conversation, type in the input at the bottom of the center panel, and press Enter or click **Send**.

<Note>
  You need a Twilio phone number connected before you can send SMS. Set this up under **Settings → Integrations**.
</Note>

## Inbound messages

When a contact replies, the message appears in the thread instantly.

## Delivery status

Each outbound message shows whether it was sent, delivered, or failed. If a message fails, the reason appears next to it.

## AI vs. manual messages

Messages sent automatically by a workflow or post-call rule are labeled **AI**. Messages you type and send yourself are labeled **Manual**.

## Automating SMS

To send SMS automatically after calls, build a workflow with an SMS action. Set the trigger condition — for example, only when the outcome is "Qualified" — and Wave Runner sends the message.
