I also got a text from this number saying "hola John?"  Didn't respond after reading Lori's post below.

Same as above. I got a call and when I responded "who is this" they replied back "lol, if you want to know, u got to add me on yahool msnger. my name is txtchikj516".I responded back and said please do not text me again.

Se exact thing "a text and same message".
It's a fisher for info out of Florida. Do not respond even with a "who's this".
They track it and get info out of your phone
Just like computer.

Got a text saying Hi Jeff!  I replied with Hi....who is this?   I have no idea who this is and I checked here to check the number and now concerned after reading a few of the other replies.
