# SMS

> Integrate SMS providers with Novu to deliver text message notifications. Configure providers, set up workflows, and manage delivery.

The SMS channel delivers messages to your subscribers’ mobile devices through your configured SMS provider integrations.

<Note>
  **SMS is outbound-only in Novu.** You can send SMS through workflows, but Novu does not receive or route inbound SMS replies. For two-way messaging, use a supported [agent channel](/agents/get-started/agents-and-providers) (Slack, Teams, WhatsApp, Telegram, or email) or handle inbound SMS with your provider's webhooks directly.
</Note>

## How SMS delivery works in Novu

Here’s the typical flow for sending an SMS notification through Novu:

<Steps>
  <Step>
    ### Add an SMS provider

    Start by adding an SMS provider in the **Integration Store** on your Novu dashboard. You can connect one or more integrations for the different or the same providers.

    To learn [how to add an SMS provider](/platform/integrations/sms#supported-providers), refer to the guide for that provider.
  </Step>

  <Step>
    ### Add the SMS channel to your workflow

    Next, include an [SMS step in your workflow](/platform/workflow/create-a-workflow). This step defines when and how an SMS should be sent as part of your notification workflow.
  </Step>

  <Step>
    ### Define the SMS content

    Within the SMS step editor, write the message body. The editor supports dynamic data for personalized content.
  </Step>

  <Step>
    ### Store subscriber phone number

    Novu automatically sends the notification to the phone number stored on the subscriber's profile. You must ensure that this field is set for any subscriber who needs to receive SMS messages. You can store subscribers phone number using the Novu API, or SDK.
  </Step>

  <Step>
    ### Trigger the workflow

    [Trigger the workflow](/api-reference/events/trigger-event) from your application code by sending an event to Novu.
    Novu automatically:

    * Resolves the subscriber.
    * Selects the correct provider.
    * Renders the SMS template.
    * Delivers the message through the configured SMS integration.
  </Step>
</Steps>

<Note>
  Some countries restrict using verified `from` sender IDs (name). Kindly check the country- and provider-specific requirements first.
</Note>

## Configuring SMS providers

To add an SMS provider from the **Integration Store**, you must configure settings and credentials that are specific to that SMS provider.

### Default sender settings

The **From** field, which is displayed as the sender of the SMS, is a required default setting for any SMS provider that you connect. You can override this field during trigger if necessary.

### Provider authentication

You must provide credentials specific to your SMS provider, such as:

* API key
* Auth token
* Account SID
* Username
* Password.

Each provider has different requirements.

<Note>
  Refer to the [supported SMS providers](/platform/integrations/sms#supported-providers) list for detailed setup guides for each provider integration.
</Note>

## Override SMS settings

You can override the SMS settings when triggerring a notification by passing the `overrides` object. The overrides object field supports an `sms` property and `from`, `to`, and `content` field overrides. This lets you send a message to a different recipient, from a different sender, or with a different content.

```javascript theme={null}
import { Novu } from '@novu/api';  

const novu = new Novu({
  secretKey: "<NOVU_SECRET_KEY>",
  // Required if using EU region
  // serverURL: "https://eu.api.novu.co",
});

await novu.trigger({ 
  workflowId: "workflowId",
  to: {
    subscriberId: "subscriberId",
  },
  overrides: {
    sms: {
      to: '+123012345678',
      from: 'Novu Team',
      content: 'This SMS message is from overrides',
    },
  },
});
```

## Target a specific provider

By default, Novu uses your primary SMS provider. If you want to bypass this and force a specific, active integration for a trigger, then use the `integrationIdentifier`.

This is useful if you have multiple active integrations for different purposes. For example, you might have one integration for transactional SMS and one for security SMS. You can find the `integrationIdentifier` in the **Integration Store** of the Novu dashboard.

      // serverURL: "https://eu.api.novu.co",
    });

    await novu.trigger({
      workflowId: "workflowId",
      to: {
        subscriberId: "subscriberId",
      },
      overrides: {
        sms: { integrationIdentifier: 'infobip-abcdef', },
      },
    });
