Hello,
I'm trying to test sending an SMS from the sandbox with phone number "18582573505", but it appears that this number doesn't have SMS capabilities.
Could someone please enable SMS for my account? Thanks!
Done. Pls try again.
Looks like it worked, the number has SMS capabilities but there's still a failure when sending the message. I can see it in the Sandbox app: 
Sorry for that.
There is a new process to provision sandbox number. You have to submit a dev support ticket and the support team will help you with.
