I got a text message from jwest@gpcom.net saying "[aler] Sears update. Call 7249289184" When I called I got a Robo voice saying it was from Sears and requesting that enter my card number. I don't have a Sears card.

except mine was for a MasterCard, which I don't own. Someone is trying to get valid credit card numbers out there. Beware.

Same here just got a text asking for a valid number. I am not calling the number.

I just got the same thing on my cell - a text saying "urgent" Master Card.  DO NOT CALL THIS NUMBER.

got this text also.  i just authorized a large purchase yesterday and thought this might be legitimate.  i called and foolishly entered in my cc #.  called mastercard, talked to them, and they didn't know anything about it.  transferred to the authorization dept, and what was funny is that they also had an automated prompt for my cc #.  I entered it again, figuring the # is no good anymore, and authorized only the amount and company that is legitimate.  i feel stupid, but they told me I'm not liable for any unauthorized charges.
