Incident Start Time: 2025-05-16 08:38 UTC

Impact for 10DLC: Delayed MT's/Delayed MO's/Missing delivery receipts/Late delivery receipts

We will update as soon as we have more information.

May 16, 2025 - 09:46 UTC
Monitoring - Sinch has received an update from AT&T, and AT&T is currently upgrading their network to accommodate the growing demands of the industry and to introduce new services.

As part of this upgrade, AT&T is migrating A2P traffic from older network components to a new gateway.
During this transition, Sinch, along with other partners, have actively migrated significant volumes of traffic throughout April and May. However, this process encountered some issues that necessitated updates to AT&T's network. These challenges did affect message processing temporarily, but they have since been resolved, and A2P message processing is now operating at the expected service levels.

Sinch remains in continuous communication with AT&T regarding the above information, and we have observed a significant improvement following AT&T's corrective actions.
We continue to collaborate with AT&T to address a few residual error types that some customers are still experiencing.

May 12, 2025 - 14:11 UTC

Update - We are continuing to work on a fix for this issue.
May 01, 2025 - 22:05 UTC
Update - We have identified that some customers are not adhering to carrier (AT&T) throughput requirements, which customers will see as throttling errors (error code 362, or 64). We have created a new Sinch Community article that outlines throughput requirements by carrier. Please review these requirements to ensure you are not exceeding the throughput requirements. If you continue to experience throttling errors, We suggest you review the article and adjust your sending speeds:

https://community.sinch.com/t5/10DLC/How-much-throughput-will-I-get-on-my-10DLC-Campaigns/ta-p/7037

Alternatives: If you haven't performed vetting for your Brand, we'd suggest you do so. Not executing vetting as part of your Brand registration may result in your Brand having the lowest throughput possible. Brand vetting should result in a vetting score which could place you on a higher level of throughput.

Additionally, we are working on several immediate, near and long-term solutions to mitigate throughput and delivery concerns customers are currently experiencing. We are in the process of fine tuning our current internal throttling mechanisms, but the full solution is a long-term project.

We appreciate your patience as we continue to mitigate the issue.
