I remember a few years ago, I saw two Nokia mobile phones at a friend's house, and I thought it was a model machine when I didn't turn on the bright screen, but I took two photos as a souvenir. Now that a few years have passed, I searched for the models in these two photos and found that the two mobile phones were out-of-print engineering machines.
It turned out that this was an engineering machine called Nokia 7700, which had never been officially sold. As early as 2004, Nokia developed the 7700, a "forward-looking" mobile phone, which was positioned as a "multimedia mobile phone" at that time. Unfortunately, not knowing what the reason was, Nokia completely abandoned the 7700 in 2005.
It is precisely because of this "change" that nokia 7700 engineering machines flow into the market, most of which are "broken versions" without a back cover, including my friend's two. But even if it is 7700 without a back cover, the second-hand market recycling price is still more than 10,000 yuan.
The picture above is a photo of the TOMPDA forum, when the Nokia 7700 flowed to the market through this second-hand forum, and the selling price seemed to be only 700 yuan. Nowadays, the global existence of this mobile phone is also dozens of units, according to the saying that "things are rare and expensive", there is still room for price increases.
