This is a residential phone number, according to an Intelius report on a former class- and school-mate that I ordered online within the past fortnight and immediately had saved in PDF document format, that I have neither contacted nor been contacted from yet.  Is this number still a residential one and if so, is it a cellular or otherwise SMS-supporting device associated with it?  If not, has it recently then become associated with a business that I'd rather avoid having dealings with?
