AT&T Text Messaging Notification Support Sunset

In response to changes implemented by AT&T, support for text message delivery of notifications from Alarm.com will be discontinued for most notifications sent to AT&T mobile devices after August 15, 2025. To ensure those using AT&T mobile devices continue receiving notifications about your Alarm.com system activity, Alarm.com will be taking the following actions:

  • Expanding SMS-to-Push Notification migration tools, targeting accounts with AT&T contacts.
  • Removal of AT&T SMS as a selectable notification option in the end-user interfaces
  • Alarm.com will continue to send alarm and other critical (specifically Two-Factor Authentication) notifications via SMS to AT&T recipients already subscribed to these notifications but will not allow new subscriptions for AT&T contacts moving forward.

We strongly recommend Push Notifications as the preferred means for mobile messaging as they provide the following advantages:

  1. Do-Not-Disturb override for critical alerts. These loud notifications are optimal for the most important alerts.
  2. Smart redirection to live or saved clips depending on whether the notified clip has been uploaded yet – letting you go straight to the action.
  3. Ability to pause notifications directly from the Push Notification.
  4. Unique doorbell sound effect.
  5. Take action from Push Notifications without having to open the Alarm.com app (i.e. close the garage door from a door-left-open alert).
  6. Continuous enhancements as iOS and Android functionality evolves.
