SMS alerts are available on our Advanced and Premium plans only and there is a .20 fee for each alert sent. Please submit an SMS credit deposit by clicking "Add SMS Credits" link in your account control panel.
You can verify that we support your SMS network by sending yourself a test SMS message.
If you have an Advanced Plan, click on "My Profile" in your control panel and enter a mobile phone number that supports SMS messages. Then check the box labeled "Send SMS Alert" within each service monitor.
