I received a text from this number in reply to an ad I had placed online in Canada. The text asked me to call back to this number rather than text reply - I know! Strange right? Right away,  this seemed odd to me, but I decided to call back anyway. When I was connected to some Global Network cell repeater that asked me to confirm the number I was dialling, I got very suspicious of this being a legitimate caller. Caller's phone number data says it's a cell phone based in Chicago IL. Anyway I Googled the number and that brought me to this website for numbers in 872 area that have been reported for similar reasons.
