Today I keep getting the message invalid number or does not subscribe to a contact who is not an iPhone user. I have deleted the contact and then put it back in, still the same problem. Any suggestions?

iPhone SE, iOS 12

Was the contact formerly an iPhone user?

If so, (s)he must de-register from iMessage.
