      Update
      Our carrier partner has informed us that messages are being queued and should therefore be delivered once the underlying issue with delivery to AT&T handsets is resolved. Twilio’s engineers continue to work with our carrier partner to resolve the underlying issue. We will provide an update as soon as we have more information.
