Just got the same text on 9/15/2010 @ 5:22 PM AZ time. I am a T-Mobile customer and have recieved similar random texts in the past. I also get CU West spam texts. I read on another site like this that this is happens to mostly T-Mobile customers. Don't know how true that is but my husband and friends get them too and we all have T-Mobile. My parent's have Sprint and never get spam on thier phones.

I got a text from     415/746-0964 telling me to call 877/861-8581 to claim my $100.00 wal Mart  card!  I did not call back after reading all this stuff.  THANKS to everyone that posted on here giveing heads up!!  Have a great evening everyone ;)

I am getting txt messages from this number and they will not stop. It is for that stupid wal-mart gift card, and wants me to reply to an 866,800 number too. Plz catch who ever is doing this

Received text claiming I won $100 Walmart giftcard. To claim prize, call 877-861-8581. OBVIOUSLY PHISHING SCAM!!!!!!! Beware... do not call back.

I got a text at 5:30 AM today saying thanks for visiting our site call 877-734-8857 to claim your $200 gas voucher.  HOW ANNOYING not just for trying to scam me but to wake me up so early!!!
