# Send SMS

The **Send SMS** function allows your agent to send an sms with any content to any destination phone number. This allows your agent to send requested information to callers such as custom booking links. This function is different than the **Notify function sms** in which the **Send SMS** function can be used during or after agent conversation (just be specific in the instructions when you want the function to be used).

Text messages that are sent from your agent will come from your agent’s phone number. Note that a paid account with a valid phone number is required to use this function. You will also need to have an **approved SMS Brand and Campaign**. Head over to the **Enable SMS** section for more information on enabling SMS functionality on your **AI agent**.

#### Adding a Send SMS Function

To add a Send SMS function to your agent:

Once added, you need to provide instructions to the agent on how and when to use the Send SMS function. You will specify:

- **Conditions**: When you have captured and confirmed the caller’s phone number.
- **Recipients**: The confirmed caller’s phone number.
- **Content**: Any specific information you want added into the sms.​

#### Example Instructions
