# Configure an Existing Content Builder SMS/MMS in Journey Builder

Use the SMS/MMS activity to power Journey Builder SMS sends to Marketing Cloud Engagement contacts in a journey. You can add SMS or MMS messages that you created in Content Builder to a Journey Builder SMS/MMS activity. MMS is only available in the United States and Canada.

To send an SMS from a journey, the normalized phone number (country code + phone number with no dashes or parentheses) is required in your data extension. The Locale field isn’t required to send an SMS from Journey Builder.

1. In Journey Builder, drag the **SMS/MMS** activity to the canvas.
2. Click the **SMS/MMS** activity, and add a name and description.
3. To access an existing message, click **Select Message**, and select the type of message: Content Builder or SMS/MMS messages.
4. Select the message to send and click **Edit Selected Message**.
5. Configure the SMS/MMS activity.
6. Click **Save Message and Return**.
7. For a subscriber-level preview for your message, click **Subscriber Preview**.
8. Click **Done**.

Referencing other Content Builder content in blocks returns table and HTML wrappers instead of text. To reference this content, use code snippets.
