Who called from 2106289853

Just got a text saying I won a Superbowl Prize of either $1000 or an Iphone5. Respond to bit.ly/11Fd6Rc    Sounds like a scam to me.....

I received a text message from 210-628-9853 saying I won a $1000 gift card from Walmart. Then my husband received one saying he won a gift card from Best Buy. I tried calling this number back, but got a voicemail saying that the customer I was trying to reach was not available. I was thrilled at first, since I have never won anything, but I should have guessed it was a SCAM.
