What the serial number of the phone does:

The serial number of the mobile phone can find out some information about the mobile phone, and the merchant also uses it as an important proof of warranty.

In addition, the authenticity of the mobile phone can also be identified according to the serial number, and the date of manufacture can also be found, but it is mainly used on hardware. When buying a mobile phone, the serial number of the mobile phone is usually filled in on the warranty card to avoid some people taking advantage of it. The mobile phone serial number has been widely used, in addition to being queried through the mobile phone, it can also be found on the headphones, Cong Shoushen mobile phone box, etc.

In addition to judging the quality of the mobile phone, the serial number can also shield the mobile phone and protect the security of the mobile phone information to the greatest extent. If you accidentally lose your phone, call your phone provider and provide your phone serial number, and they will help you block your phone so that even if the thief changes the SIM card, it still can't be used, which minimizes the risk and damage. <>

This is the serial number of the replaced product. It is recommended to contact Apple customer service.

Several theories about black machines:

1.The profiteer took the motherboard and said.

For example, the profiteer has an Apple mobile phone with a serial number of f18jw6yedtwd. Then the phone was about to be out of warranty, and then he took away the motherboard of the f18jw6yedtwd machine, and then installed a broken motherboard, and then said that the phone was broken and took it to the after-sales warranty, so that it was replaced by a brand-new official machine from the after-sales service. Apple will then cancel the serial number F18JW6YEDTWD in the warranty system database and mark it as the serial number of the replaced product.

At this time, the profiteer mobile phone has a brand new official machine, and there is also an F18JW6YEDTWD all-good motherboard. Then the profiteers will get some parts, assemble the f18jw6yedtwd motherboard into a complete machine, and then sell it to you. So if you look up the serial number of F18JW6YEDTWD, this result will appear.

In this way, F18JW6YEDTWD has become a black machine, and there is no warranty for such a machine. Because Apple's after-sales policy is to only replace and not repair, there are profiteers at home and abroad who engage in this set of motherboards and then assemble them to make black money.

2.Report the loss and deceive the insurance said.

There are also some theories that the original merchant bought this mobile phone, and then bought an insurance for the mobile phone, and then sold the mobile phone to you, and he was reporting the loss to Apple, so that Apple would compensate him for a new mobile phone, so that he earned one, but the original mobile phone will be backed up as a black machine in Apple, and the serial number will be canceled, and the warranty or something will of course not exist!

The above statement is just speculation, and if you want to know the specific reason, it is best to call Apple after-sales consultation.
