I got a call this afternoon about 4:50pm US Mountain time from this number on my cell phone (T-Mobile network).
I kinda regret not answering it to see if it there was some kind of pitch behind it.  I just now remembered to google it and see if it was someone I knew, but like everyone else it's no one I know.  

I'm assuming it's an auto dialer of some sorts that's probally out looking for valid phone numbers.  I'm sure I'll be getting a spam text message in the next few days or another call from someone claming to be from a bank in Nigera offering me millions of dollars.
