Just got a call from this number, when I answered the red flags went off so fast it was not funny. Claimed to be from Sprint Accounts, claiming my account (which I don’t have one) was flagged and to enter my security pin. Well I hung up. At that point I called my Cell phone company (T-Mobile) to report it. They also advised me I should call Sprint to report it there, just in case some one did get a hold of my old account (my phone number is still the same from when I had sprint, thanks number portability) Good news is that nothing wrong there, and that they were starting to get reports of this scam, and that they were trying to let their customers know.
I post this here so just to spread the word as I have friends that use sprint and just want to get the word out.

It is probably best if you get a call from 800 000 0611 that you don’t even answer it.
