## SMS Notification Module
The **SMS Notification Module** allows you to deliver SMS alarm notifications via a cellular modem configured with a SIM card belonging to an active cellular account. If enabled, recipients of these messages can reply with a special code in order to acknowledge the alarm.
:::note
The SMS module is dependent on the Alarm Notification Module. You must have both modules installed to send alarms.

### Device Configuration
Inductive Automation officially supports three Airlink Devices: the RV50, the Raven XE, and the LS300. Most devices from most manufacturers can be used, but some configuration settings might be different. You can do the basic configuration for the Airlink modem by importing a template settings file provided by Inductive Automation.

### Multiple Systems with One Modem
You can use one SMS modem with multiple Ignition systems for one-way (outgoing) messaging. If you want to use two-way messaging (incoming and outgoing), then only one Ignition system can receive those incoming responses.
## Create an SMS Notification Profile
1. Go to the **Configure** section of the Gateway.
2. Choose **Alarming > Notification** from the menu on the left to open the **Alarm Notification Profiles** page.
3. Find the blue arrow and click on **Create new Alarm Notification Profile**.
4. Select the **SMS Notification** profile type and click **Next**.
5. Set the following settings concerning your device, and then click on **Create New Alarm Notification Profile**.
- **Name**: SMS
- **Description**: Optional
- **Enabled Box**: Click to Enable SMS notifications.
- **Airlink Host Address**: The IP address of the Airlink modem.
- **Send Port**: The default port is 17341, which is configured in the device.
- **Receive Port**: The default port is 17342, which is the port used by Ignition when two-way messaging is enabled. The port must not already be used by the host system, and must not be blocked by a firewall.
- **Two-way Enabled**: If enabled, the message recipients will receive a text message notifying them of an alarm, and a link to acknowledge the alarm. This is communicated to Ignition via UDP data sent from the modem. Therefore, the Airlink modem must be configured with the IP address of the system.
- **Numeric Only Ack Code**: If this is true, the ack code sent with the SMS message will be a numeric code instead of an alphanumeric code.
- **Audit Profile**: If an audit profile is selected, events such as SMS messages and acknowledgements will be stored to the audit system.
Once all the settings are entered, click the **Create New Alarm Notification Profile** button.
6. Once you have the SMS Notification profile set up, you can add phone numbers to your contacts using the **SMS** Contact type.
## Twilio Module
SMS notifications can also be sent with the [Twilio](getting-started/ignition-modules/additional-modules/twilio-alarm-notification.md) module. This does not require a cellular modem, but the Gateway must have Internet access, and a Twilio account with SMS capabilities must be created (www.twilio.com). Once created, the account must be defined in Ignition.
:::note
The Twilio module is dependent on the Alarm Notification module. You must have both modules installed to send alarms.

### Defining a Twilio Account
1. Go to the **Configure** section of the Gateway.
2. Choose **Twilio** > **Accounts** from the menu on the left.
3. Click the **Create new Twilio Account** link.
4. Provide a **Name** for the account as well as the **Twilio Account Sid**, and **Twilio Auth Token**.
- Both the Account SID and Auth Token can be retrieved from the Account Settings menu in Twilio.
5. If desired, provide the **Public Hostname**. This is the hostname or IP address that inbound requests will be forwarded. If the users should be able to acknowledge alarms by responding to the SMS messages, then this property should list a publicly reachable hostname or IP address.
6. Click the **Create New Twilio Account** button.
Once the account has been defined, a Twilio SMS notification profile must also be created.
### Creating a Twilio SMS Notification Profile
1. Go to the **Configure** section of the Gateway.
2. Choose **Alarming** > **Notification** from the menu on the left to open the **Alarm Notification Profiles** page.
3. Find the blue arrow and click on **Create new Alarm Notification Profile**.
4. Select the **Twilio SMS Notification** profile type, and click **Next**.
5. Provide a name for the profile, and select a **Twilio Account** from the dropdown.
- **Acknowledgement Allowed** enables users to respond to notifications directly from the SMS message; also known as **Two-Way notification**. If enabled, the **Public Hostname** property in the Twilio Account must be configured (see step 5 in "To define a Twilio account" above).
6. Click **Create New Alarm Notification Profile**.
:::tip
Once your Notification profile is created, you can use it in an [Alarm Pipeline](alarming\alarm-notification\alarm-notification-pipelines\alarm-notification-pipelines.md).
