Message processing has returned to normal, and all queued messages have been delivered. SMS messages sent over 10DLC long code numbers to AT&T subscribers are now being delivered without delay. We are continuing to monitor traffic closely while our downstream partner and AT&T complete their investigation into the root cause. We will post a final update once the incident is resolved.

We are investigating delays in the delivery of SMS messages sent over 10DLC long code numbers to AT&T subscribers, beginning October 6 at around 15:00 UTC. Messages are being accepted but may be delivered later than expected to AT&T handsets. Messages to other carriers are not affected. Our team is working with our downstream partner and AT&T to identify the cause and restore normal processing. We will provide further updates as more information becomes available.
