While I'm rambling on a bit, I spent 4 years as a mobile phone salesman shortly after uni more than 20 years ago now. I started when phones were all contract, for the well off and business types. Analogue phones were still around and although digitization was changing the market place, some phones were actually still quite hefty. I think the Motorola Startac was the first phone to weigh under 100g(?). That was £1400 when it first came out in 1996. (Apple aint trying hard enough) I ended up with an end of the line one a couple of years later for £30 (which indicates how fast the tech was developing then).
I was also there when "pay as you go" came out. It was that, imo, that changed the mobile from a high end, up market, exclusive item to the everyday commodity that pervades our world today. My job changed from making the customer feeling important and exclusive and upselling them (usually him) on accessories, insurance and features, to a pile 'em high, sell 'em in bulk, bargain bucket, lowest common denominator job within a couple of months, selling to every Tom, Dick and Harriet.
That job changed me. Mobiles sell themselves. Our job was to sell the add on things people didn't want and that is what our performance was judged on. I'm not a natural salesman so to survive in that environment I had to do things that goes against my nature. I came out of that job not liking myself much but have been much luckier since.
