Who called from 4197754998

Text message from 419 775 4998, requesting to be added to messenger. Replied I do not use messenger. Response was, "Lost signal"

I got a text today (01-04-2013) from this number that referred to me by name.  When I asked who it was, there was a "Sorry, little service :-(" message.

Received a text of "Heyy!" from this number.  Asked who it was, and they sent only a Skype ID (Baileyflirter).  Sent back that I'm not interested, and last message was "Sorry, no signal."
