I received a text message saying:
"Hey :P"

from phone number (540) 784-4025.  I have no idea who this person is and they did not respond when I asked "who is this?"

I received the same message but from 830 264-2723.  It went

"Heyyy (my name)"

They replied "sorry I have no signal ;(

I personallly think its a message that is sent to people who have been on some kind of chat line and they get you to wonder who is trying to get a hold of you.  They also will send out messages that make it look like someone is wanting to meet you but then you have to sign up with somekind of chat line or something.  Avoid these chat lines at all cost.
