I got a Wireless Caller as an ID on a Sunday at 11:39 am. I was at church. He didn't leave a message so I called back to one ring and dead air. I will complain to the FTC. I am on the Do Not Call list.
He sent me a text message as though I had called him and he was just getting back to me about earning $50 k from home. I asked who he was with and he just said he worked from home with multiple money streams. When I asked how he got my number he said he invests in leads and is only for folks who are looking to make money from home. Then he wished me the best of luck and said he could see it wouldn't work.
Based on my experience in information security I'd make a bet he is a scammer.
