How to distinguish authenticity:
You can search Baidu-telecom equipment network management, enter the website to verify the mobile phone network access license and mobile phone serial number, as long as it is a real mobile phone will be registered in the database;
Mobile phone serial number is the only serial number when the mobile phone is produced, and it cannot be repeated. Enter *#06# to check whether this number is consistent with the label on the back of the mobile phone and the bar code of the packaging box after the battery is removed. These three numbers are the same as the three-code machine;
In addition, if the warranty card is also affixed with the same serial number certificate or the numbers of other related accessories, and these five numbers are exactly the same, it is called a five-code machine;
In the past, fakes could not be consistent, which is a good way to distinguish between true and false. However, with the development of technology, a large number of cottage mobile phones can achieve three or even five yards consistency; Therefore, the number can no longer accurately distinguish between true and false mobile phones.
