# Chat

> Let your agent converse with leads by text, on its own or alongside a call.

Enable **Chat** in the agent’s channel controls to let it hold conversations by text.
Your voice agent remains available when Chat is off.

## Set up texting

1. Enable Chat.
2. Open **Inbound → SMS** to review the sending number and any setup message.
3. Resolve missing-number or approval issues in your connected CRM.
4. Select **Recheck**, then try a message in the test panel.

The number is shown directly in the SMS section. If approval needs verification,
check that sending number in GoHighLevel. Detecting a number is not confirmation
of A2P approval; GoHighLevel does not expose that approval through its number API.
The status can also show the latest known send failure.

With native CRM, live texting needs a supported approved sending number. Chat
tests remain available even when live SMS setup is incomplete. Voice can still
go live if its own setup is ready.

## Calls and texts work together

A text received during a call belongs to that same conversation. The agent can
use it while speaking and, when Chat is enabled, send a supporting text.
Continuing by text does not mean starting the introduction again.

Turning Chat off removes conversational replies by text. It does not remove
fixed **Send SMS** steps from your [workflows](/agents/tfu-live-capabilities).

## Adjust the writing

Open **Conversation Style → Chat style** for message length, tone and punctuation.
Change services, offers or answers in [Instructions](/agents/tfu-live-brain).

[Test both channels](/agents/tfu-live-testing), including a message sent during a call.
