Who called from 6073414752

Recieved a text that read Hi Kim from this number.  No other message.  No info.  They have my name correct, but I don't know who this is.

I received the same text today . Just said , hi Jason ??? . Probably another crafty bill collector .

I received a text saying hi corinna replied and got nothing back. Who is this person?

I recieved this message and was sent back "haha if u wanna know who this is you got to add me on yahoo msger. my name is textiechick93"  I replied "I don't use yahoo messenger either tell me who u r or delete my number"  I haven't gotten another reply from them as of yet, but I think I'm gonna have to speak with Sprint.

Received a text that said "Hey Sara...."
