Yup, my voicemail box is constantly full of spam messages to the point where, my voicemail's regularly full, I couldn't be bothered to listen to any of them any more and it's too much effort to clean it out. My last carrier used to send a text if I got a voicemail. If I got a text saying I got a voicemail from someone I knew, I'd call back, if it was a random number, I'd just delete the text.
