Same here! They called me by my nickname, not legal name. Said to look them up on Yahoo Messenger Allisonflirt18. When I said I don't know you, they responded with "Oh no I have no reception :( " This is twice in a week. Defferent #'s and different screen name. Exact same conversation though, right down to the lack of reception.
Looks like I'm not the only one. I got a text from an 813-445-4939 same '"faithgirl6" mentioned here. Wants me to add her on Yahoo messenger. Asked who it is, no reply.
