This number is running a scam by sending text messages to cell phones stating you have won a $1000 walmart gift card and providing a link to claim your prize. You are led to believe it is a Walmart message.  They will ask for all your info including your date of birth.  DO NOT PROVIDE THEM AND INFORMATION.  Google the $1000 Walmart gift card giveaway and you will see what is going on.  Walmart never sends text messages.
