"What does the "serial number invalid" query result mean?" The serial number does not exist in the Apple official database, commonly known as the black machine. So what is the black machine? Sister and sister take a trip together with everyone. Tips: Sometimes it is possible to enter the wrong serial number. The serial number is a mixture of 12 letters and numbers. Sometimes we will enter 0 (zero) as O, and there is no letter O in the serial number. iMEI is a 15-digit number. "What is a black machine?" As long as the serial number is queried on Apple's official website, devices that indicate that the serial number is invalid or have replaced the product serial number can be collectively referred to as "black machines."

Such machine refurbishment machine has a high probability, some of the accessories are not original, prone to failure, can not enjoy Apple's official warranty, do not recommend buying. "Is it true that black machines on the Internet are so reliable?" Lost serial number It may be that the mobile phone was stolen from the mobile phone. When the missing mobile phone is lost, it will report to Apple. Apple will cancel the original serial number. This phone will become a black machine. However, in fact, this kind of device is called an ID machine. Apple has no right to unregister the original serial number of the device, but instead locks it. Purchase insurance machine When the original merchant bought the phone, he bought an insurance for the phone and sold it to you. When he sells the phone to you, he reports to Apple again. At this time, Apple will pay him a new mobile phone so that he can make a new device without spending money. The phone that was sold to you was Become a black machine. In fact, this statement is incorrect. Apple's insurance coverage for the iPhone is Applecare+ (entitlement service). The Applecare+ service does not include the loss of mobile phones. So there is no longer a case of losing a new iPhone. "What does the "serial number of replaced product" appear? This type of equipment is a problem that the profiteers bought after the sale of Apple's products and then sold them again. Such equipment has been replaced, and the original serial number has been canceled, so the serial number of the replaced product will be indicated. The machine is a real machine, but some internal components of the device may be non-original and can not enjoy the Apple warranty. Tips: Apple's after-sale service will be based on Apple's warranty policy maintenance terms to some of the issues in the warranty period directly for a new device, the problem machine recovery after returning to the factory maintenance, but there are also some of the flow to the market (profiteers obtained by some means). "Is this type of "replaced product serial number" equipment available for purchase?" Like the black machine, it cannot enjoy the official Apple after-sales warranty. It is unable to check the warranty period. Some components in the device are not original, and the failure rate is high. It is not recommended to buy. Small partners, although the query serial number can quickly determine whether the new machine is not activated, whether the warranty, whether the black machine, whether the official replacement, whether the ID machine (you can visit the public technical number menu query), but used to It is not enough to identify the refurbished machines, but don't worry.
