At this time, AT&T is blocking SMS deliveries from YouCanBook.me notifications.
YouCanBook.me users who use our SMS feature to send SMS to AT&T phones have reported that recipients on the AT&T carrier are not receiving SMS due to this block by AT&T.
This block is only happening with AT&T numbers – all others are being successfully delivered. We currently have a ticket open with our development team to adjust our SMS routing to prevent this block.
We will continue to post updates on this issue as progress is made.
