Who called from 6606684783

Just got the call awhile ago from this strange number.  I didn't answer it, but of course googled it instead!  Some people have nothing better to do than make prank phone calls...gee I wish I could have that interesting life!

I got a call from this number about an hour ago but i didnt answer because i was in class. Googled it and found this. Glad I know it wasnt important apparently.

Got just a 'hello....?' and I answered back 'hello?' hoping to know who it was...but they just hung up...

Got the same thing as everyone here. A hello, and no answer.

someone just called and i answered, but could hear nothing on the other end.
