Twilio: Increased SMS Filtering to AT&T
Timeline of updates
- resolved
We have investigated the issue of increased carrier filtering on SMS traffic to AT&T US from a subset of local long code numbers. It was determined that we are observing expected filtering behavior for messaging sent without a registered A2P Campaign. All systems are operational. If you experience message filtering toward AT&T on a registered A2P 10DLC Campaign, please submit a ticket to Twilio Support.

Rewindex commits each version of an incident it captures to a daily checkpoint, chains it to the day before, and has the checkpoint timestamped by FreeTSA and DigiCert.
How the archive is checked, and what it cannot prove.
This incident predates live tracking (October 17, 2026). It came from the vendor’s own published history, which is not covered by checkpoints.
