Dear Sinch Customer,

Throughout September and October AT&T will be performing upgrades and improvements to their core messaging services in preparation for peak season volumes. As a result of this AT&T will re-deploy some Sinch services onto a new, higher capacity AT&T platform.

Though no infrastructural changes will be made on the Sinch platform Sinch will work closely with AT&T to facilitate their network upgrades. The next maintenance window is detailed below:

Maintenance start time: 2023-10-05 07:00 UTC
Maintenance end time: 2023-10-05 08:00 UTC
The new AT&T platform does not yet support binary messaging; please contact us to discuss this or any other aspect of the AT&T platform improvement.
