Received text about testing IPhone5

I got a text from +1 (718) 473-5929 asking If I wanna try a iPhone 5 out
And I'm only 11 with a iPhone and not rich but really dont sent me that if I'm 11

Don't get your hopes up or waste your time on this one. It's from a company called value opinion center operated by Research Now. After entering your information you have to then sign up for 10 different offers in order to qualify for a chance for their offer.

This company is in no way associated with Apple and if you think that they have any chance of landing an Apple iPhone 5, think again. Apple has extremely high privacy standards regarding their products and wouldn't let random people get their hands on an iPhone5. You reward after signing up for the 10 offers (and not cancelling more than 2 within 30 days) will be an chance to get an iPod Touch.

Got a spam text message from this number about receiving an iPhone5 beta for test.

Received a text message on my Cell Phone from this outfit.  I have a pre-paid minutes cell phone provider, and I was charged a .30 minutes for this text message.  How do these companies get access to my cell phone number?
