Cell phone Spam getting out of hand!

Wish there was a way to block all this crap!!!
Now whenever I get a suspect call/text found it best to run a 'Google' on it before responding. Google usually reports where the call is from and who is sending all this computer generated crap wasting and using up your minutes!!!

Had to bring this up because a couple minutes ago I got a call from this site in Viet Nam of all places!!!
