I got a text from this number saying they were looking for people to test & keep an ipad 3 along w/ a url.

I don't even know how.... apple I pad 3? With link?

This is a scam.  The caller is NOT Apple or Walmart.    Repeat: This is a scam.  Do not respond in any way.  Simply delete the message.  At least some of these messages are directing people to a malicious site.  Do not let curiosity get the best of you.

Please do not post working links to scam web sites.  You can break the links like this:  www.google (dot) com so that no one accidentally winds up on a malicious site.

Thanks.
