got a few of these calls, have Mr Number app to  black on my cell.

They just called me. Same exact thing as everyone has described. 1 ring, hang up. Great to know that it can be labeled as spam. Thanks everyone.

This number has been notorious for calling me once about a week. It's getting pretty annoying. As earlier described I get the one ring before they hang up.

They called and didn't leave a message. They didn't even wait long enough for me to pick up the phone, as my ring tone normally goes on longer than what I heard when they called. I bet Captain Smirk is right, but I can't imagine where they got this number.

No Message was left...I called back as I am a Cancer Patient in Tampa and Several Doctors call on any given day and I did not want to miss something important. When I called back I received a recording that started out *Welcome, we were calling you as you expressed an interest in.....* and that is where I hung up, as I NEVER give my number to random people or places!

Think about the reason why they call and hang up - they're getting YOU to call THEM - and that way they can say that YOU called THEM about their product if the law asks! This way, they aren't getting any heat for making unsolicited calls to a cell phone, in which the penalties for repeated calls can be very, very, expensive.

Ditto. They called my cell too. No message.

I called back. Recorder offering $100 prepaid card if you buy someyhing on the web.

Ditto. They called my cell too but hung up after one ring. No message.

This number is on my cell as a missed call. No message left.

Received a call from this number on my cell phone. I didn't answer since I didn't recognize the number and there was no caller ID. They didn't leave a message.
