So all of a sudden I'm not able to send a message to a number that I've send messages to on a regular basis. The number is in my contacts, nothing as changed and I did test to see that I'm able to receive messages from this number. I successfully sent a message to this number just yesterday. If type the number in the message goes through. I tried deleting it from my contacts but it's pulled in from FB so it won't let me. Any ideas?
