Re: it wont let me send a message to one perso

It means that the number you're sending the message to isn't authorized to receive text messages. It can be that you're sending the message to someone's home or work number, or that you have the country code in the number and you're in that country, or that you entered the number wrong.

The fastest fix is normally to delete the contact and create it again, making sure that the mobile number is actually a cellphone or other device that can receive SMS.
