Received text June 11/12:  "Congratulations your number made you Walmart's winner of the day! Go to htt://www.walmart.com.wonacontest.com to claim your prize! You have 24 hours to claim."

Haven't shopped at Walmart in more than 5 years (and never will) and referencing Walmart's corporate site clear indication that this text is a hoax.

Placed a voice call to the number, goes direct to voicemail saying the voicemail has not been set up.

HOAX!!

"Congratulations, your number made you Bestbuy's winner of the day!  Goto http://www.bestbuy.ca.wonacontest.com to claim your prize!  You have 24hrs to claim".  I got the exact same message on my second cell phone seconds apart from a different number.
