I got a text message from this number on 9/04 - I ignored it since I didn't recognize who it was from. There are only "3" people who text me on a regular basis and none of them are in the 657 area code...

This was likely a wrong number thing, or some advertisement text, who really knows?

Be that as it is, if you don't recognize the number or in this case who the text is from - ignore it!
