Who called from 4027096422

I received a urgent text message from the same number, but no area code, and when I looked at the sender, and it had 7 numbers I was sure this was a phone number, saying that my YAHOO alerts are being turned off, and to log in. I'm wondering if it's a keystroke logger/hacker. Its so weird that now 3 email companys that we use was the topic. My phone is a refirbished so that makes me wonder even more now. And does anybody know, what this numer is? My refirbished phoes previous number owner has bill collectors calling me constantly trying to find the previous owner, so is this a collection agency, or is there some kind of program that can be used to trace keystrokes on a phone through a text message, or something like this? Thanks

THIS WAS A SECURITY BREACH. My main AOL mobile mail acct. no longer works and cannot be validated any longer. I have cancelled the feature on my phone and encourage others to do the same. (I use Cricket so maybe it was a Cricket thing as well.)

The same thing just happened to me...I googled on my laptop and read your messages..I deleted that off my phone!  Thanks!  Did cricket have anything to say about what happened.  I logged in on my computer and changed my password.
