# Adding SMS reminders in a workflow

In addition to sending **email reminders** for an upcoming meeting, you can also **add SMS reminders in a workflow**.

Let's see how to **include SMS reminders in a workflow** to send **text messages** to the cell phones of people who have made a booking and remind them of their next appointment.

> [!TIP]
> To send SMS, you must have your own **Twilio account** and set up the [integration between TuCalendi and Twilio](https://www.tucalendi.com/en/s/integrations/integrate-twilio-with-tucalendi).

[We will edit an existing workflow](https://www.tucalendi.com/en/s/flows/editing-an-existing-workflow) and add the option to send SMS reminders.

The current workflow has three **automations**:

- Send confirmation email.
- Send two reminder emails.
- Send cancellation email.

[Log in to TuCalendi](https://account.tucalendi.com/). Go to the **"Workflows"** menu:

![Flows menu](https://www.tucalendi.com/images/content/flows/en/flow-menu-four-types.png)

Under the **"Workflows (after booking)"** option, click **"Select"** and your available workflows will be displayed:

![Workflow with events](https://www.tucalendi.com/images/content/flows/en/workflow-with-events-assigned.png)

Click **"Edit"** on the workflow you want to modify by adding the option to send SMS reminders.

The workflow will be displayed in its current state:

![Workflow with three triggers](https://www.tucalendi.com/images/content/flows/en/workflow-with-three-trigger-and-actions.png)

Look at the **"Before a booking/meeting starts"** **trigger**, because this is where we want to include the option to send SMS reminders.

Click **"Add new action"** to include a new reminder or **"Edit"** to update existing reminders:

![Schedule-reminders](https://www.tucalendi.com/images/content/flows/en/schedule-reminder-emails.png)

Set when you want the reminder to be sent, the **reminder template** you want to send and the **email account** it will be sent from. Then, **in the "Send SMS notifications" field, activate the appropriate option, e.g. "Send notification to customer"**.

> [!WARNING]
> Please note that reminders will **always be sent by email**. The SMS reminder is **optional**.

When you have configured the reminder, click **"Apply"**.

In our case, we want to send two reminders as follows:

- **One day before** the booking, only an email reminder.
- **One hour before** the booking, the reminder will be sent by **email and SMS**.

To do this, we need to add **two actions** to the trigger.

First, add the reminder for 1 day before. Once it's added, click **"Add new action"** and include the second reminder for 1 hour before the meeting.

The reminders will now appear in the workflow with the settings you have made. All you have to do is click **"Save"** to apply the changes.
