SMS system failed to lookup the users LRN to route the message probably. Just click it and try again.

Switched from iPhone to Android and did not de-register their iMessages account?

That’s likely. It was sending iMessage because it’s blue.

I did try again on that phone to no avail. On a different iPhone I didn’t get that error. Does this exact error happen when you’re blocked?
