Who called from 4433455489

some one just sent me a text. had a mystery number text me yesterday also. number was 8318240559 also i have t mobile as a cell phone provider.

Got a text from this number and all it said was "Hey Josh.." - clearly a phishing exercise to see if my number is being used.

Received a text from this number saying "hey Tom..".  Made the mistake of answering

I received a text from this number just saying "hello Camille!!" And when I asked who it was no one has replied.

I received a text Nov. 12, 2012 mid-afternoon saying "hello JoAnn!!" I replied who is this & did not get a reply.
