You've missed the point. The FCC states that telemarketing calls to cell phones are illegal in most cases.

They called and they hung up and when I call back to find out what it was about they said that I won hundred dollars and so then they asked me my name and my address in then on they said they'd send  package with the hundred dollar gift card in about a week and then so that we could mail this out they asked  $3.95 for shipping and handling and then they requested or asked for a credit card so they can send them package out.  Very noisy background and they all had hard time hearing you.  It is a scam!

They called a number that no one should know, so it's probably a scam.  I wouldn't know since it rang once and then hung up.

barely called. hung up. it's cool, i didn't want to talk to them anyway.

Got a call on my cell phone, which is not a number known by many people - or so I thought!  It was a "missed call" on 4/20/13 at 11:58 am - no message.
