# SMS

> Connect a Twilio number so inbound texts land in Conversations

SMS uses an organization Twilio number. Customers text that number; threads appear in the chat inbox.

## Prerequisites

* Twilio numbers already added at the **organization** (the same numbers can be used for voice)
* Permission to create channels

## Connect

<Steps>
  <Step title="Open Channels">
    In the project sidebar, select **Channels**. Select **SMS**.
  </Step>

  <Step title="Choose Twilio number">
    On **Choose Twilio number**, select the number customers will text. One number per SMS channel.
  </Step>

  <Step title="Finish">
    Complete the wizard until you see **SMS Channel Connected!**
  </Step>
</Steps>

If the product cannot set the Twilio Messaging webhook automatically, copy this channel's webhook URL and paste it on the number in Twilio (Messaging webhook).

## Verify

<Check>
  Text the number from a mobile phone. The message appears in [Conversations](/docs/operate/conversations).
</Check>

## Use it

Inbound SMS uses the chat workflow and tools you attach in channel settings. Replies go back out as SMS on the same Twilio number.

## Limits

* Identifier is the E.164 number (starts with `+`).
* If the number list is empty, add a Twilio number in organization phone settings first.
