Not exactly a phone call, but I received an IM asking me to text this number without much else. I looked it up online and found other net postings asking to text this number. Something about a weight loss program or something relating to weight loss, but it smells like spam, so I would avoid.
I got an IM on my Yahoo messenger this morning also saying the same thing to 'text me 206-489-6770. I check this number out using reverse look up and all they said was its in Seattle, WA... one said it wasn't a vaild phone number.
