SMS messages not delivered to AT&T mobile numbers
Incident Report for Proxyclick
We still see a high error rate in delivering SMS messages to AT&T mobile numbers.
We are working on a few tracks: we are escalating though our SMS gateway provider to AT&T and are bringing technical changes to the SMS structure in order to improve deliverability.
In the meantime, if your hosts report this issue, we would recommend that they report the issue to AT&T via this link: We will post updates on this page.

We've noticed that SMS sent to AT&T mobile numbers are currently not being delivered because of filters put in place by AT&T. We believe this is due to more strict filtering that AT&T has recently put in place for application-to-peer (A2P) type messages. We're working with our SMS gateway provider to identify solutions and will post updates on this page.
