# SMS Chat

> This page describes how to use SMS chat with QCall AI

## SMS Chat

QCall AI allows you to send and receive SMS messages using the phone numbers configured on your dialers. SMS chat is automatically available once you have a dialer set up with a valid phone number.

## How to Send SMS

There are two ways to send SMS messages:

### 1. During a Call (Action-Based)

You can configure your assistant to send SMS messages during or after a call using the **sendMessage** action.

Follow these steps:

1. Go to **Assistant Settings** under Call Platforms
2. In the **Actions** section, add a new action of type `sendMessage`
3. Configure the SMS settings:
   * **is\_sms**: Enable SMS messaging
   * **description**: Condition text describing when to send the SMS (e.g., "Send SMS when the customer requests a booking confirmation")
   * **content**: The SMS message content (supports custom variables like `{{first_name}}`)
   * **end\_call\_sms**: Send SMS after the call ends
   * **end\_call\_sms\_not\_answered**: Send SMS if the call is not answered

### 2. Bulk SMS via Campaigns

You can send SMS messages to an entire tag list by creating a campaign with SMS actions enabled.

## SMS Best Practices

* Keep messages concise and clear
* Use custom variables to personalize messages
* Include a clear call-to-action
* Respect opt-out requests immediately
* Check local regulations for SMS marketing compliance

## Limitations

* SMS messages are limited to 160 characters per segment
* International SMS rates may vary based on your dialer provider
* SMS delivery is not guaranteed and depends on carrier networks
