--- title: "SMS Notification Profile" --- # SMS Notification Profile > >

The SMS Notification Profile allows you to send alarm notifications over a cellular network using a supported AirLink modem. It supports both one-way and two-way SMS communication, including alarm acknowledgments via SMS reply if enabled. This profile is commonly used in remote environments where network access is limited, but cellular coverage is available. ## SMS Notification Module Short Message Service (SMS) is the protocol used by most text messaging systems. The SMS Notification module enables SMS alarm delivery using a cellular modem configured with a valid SIM card. If two-way messaging is enabled, recipients can respond to alarm messages with an acknowledgment code. :::note The SMS Notification module depends on the Alarm Notification module. Both must be installed and running. ::: ### Device Configuration Inductive Automation officially supports the following Sierra Wireless AirLink devices: * RV50 / RV50X * RV55 * LX40 Other modems that support the AirLink IP protocol may also work, but may require additional configuration. Template settings for supported devices are available in the following Knowledge Base Articles: ### Multiple Gateways with One Modem A single AirLink modem can send messages for multiple Ignition systems in one-way (outgoing only) mode. However, only one Gateway should receive incoming SMS responses if two-way messaging is enabled. ## Create an SMS Notification Profile Follow these steps to create an SMS Notification Profile. 1. In the Gateway, go to **Services** > **Alarming** > **Notification**. 2. Click **Create Profile +**. 3.

Enter values for your device into the required fields. In this example, we used the following: * **Name**: SMS * **Airlink Host Address**: The IP address of the Airlink modem. * **Send Port**: 17341 * **Receive Port**: 17342 * **Airlink Backup Host Address**: The IP address of the backup Airlink modem. * **Backup Send Port**: 17341 * **Backup Receive Port**: 17342 * **Two-way Enabled**: True ![Configure SMS Notification Profile](sms-setup.png) 5. Click **Create Alarm Notification Profile**. 6. The profile appears in the list and will begin running immediately.
