Received a voicemail from the number 18056377243. The number does not appear on the received call log but shows when launching the "listen to voicemail" feature on my cell phone by hitting the voicemail "key". The message is a very poor recording with what sounds like someone making static noice with a very low volume voice saying what appears to be "I'm watching you. I know what you're doing. I'm going to kill you."

Geez people, has no one tried calling this number back?

It is the voicemail system for TMobile. I use it all the time to check my VM messages from my home phone. You have the option to 1.) Check your own message or 2.) Leave a VM message for another TMobile user.

Anyone can leave you a voice mail through 18056377243 without ever having dialed your number. So it is an ideal number for pranksters to use.

What is so mysterious about that??

Right, but I guess you haven't thought of oh... maybe dialing the number directly from your cell phone? Bet it'll go straight to the voicemail system. :/

She's checking her voice mail.

I have had a half dozen calls from this number. The longest was 1min. 16sec. When I called back ontty (hearing impaired) they told me if I have a message box to give the number.
