Raven -- I can't speak to the error message. I will say that groups.io uses SMTP to send group messages, not SMS. It seems unlikely that anyone attempting to sign up with a texting-only address will have a satisfactory experience, even if they are successful.

Looks like T-Mobile doesn't like groups.io sender addresses. Is there a workaround?
A groups.io mobile app is under development. There has been no release date established, but with the continued Y!G influx it seems reasonable that will be pushed back.
