I just got a brand new iphone 4 phone from my friend (not even used, she got iphone 5 from her boyfriend so gave me this). I'm on a family plan, in which my boyfriend and I are on together. He's an android, however. I can text everybody else but him. Don't bother asking me if I could call him still - I do not call because I am Deaf, it's pointless for me to. I tried deleting his contact information and previous, attempted messages. I tried eliminating the +1 thing in the phone number. Nothing works. I still get the exclamation mark, informing me that the text did not get through. Help.
