Method for distinguish whether to renovate that machine:

(1) Look at the IMEI code (the three codes should be consistent)

This code is the so-called mobile phone serial number. In fact, it is a mobile phone ID card. It consists of 15 digits, corresponding to each mobile phone one by one, and the code is unique in the world.

Query the IMEI code of the mobile phone, enter [*#06#] on the mobile phone, and the IMEI code will be displayed on the mobile phone; Open the battery cover of the mobile phone and you can see a sticker with an IMEI code on it. Finally, look at the sticker on the outer box of the mobile phone. There is also an IMEI code here.

If the mobile phone is genuine, then the three IMEI codes will be exactly the same. When the three codes are inconsistent, it means that the mobile phone may be a refurbished machine or a fake mobile phone.

(2) Look at the network access license

The location of network access permission is similar to the location of IMEI code. When you find it, take a closer look. There is really a watermark on the network access license, and the surface color is uneven, from deep to light, from thick to light; Most of the fakes are imitations, and the surface color has not changed.

If you can't see it with the naked eye, you can take a photo on the money detector. The real network access license will display the red "CMII" anti-counterfeiting pattern, while the fake network access license's anti-counterfeiting pattern is blurred. In addition, you can also check the authenticity of the network access license in official website.

(3) Look at mobile phone accessories

The accessories of refurbished mobile phones are generally incomplete or not original products, and the accessories of fake mobile phones are relatively rough. If you are not sure, you'd better bring your friend before buying a mobile phone, and this friend had better use this mobile phone to compare it on the spot (if everyone buys fakes, it is at least a psychological comfort).

And as long as it is metal, it will leave metal scratches on the charger plug after several uses, so take a closer look. Similarly, you can also observe whether there are metal scratches on the SIM card slot.

(4) Look at the screws

If the back cover cannot be removed, there are screws outside; The back cover is detachable and the screws are inside. The screw of the refurbished machine has been unscrewed, and this process will leave scratches on the screw, which can be seen at a closer look.

(5) Look at the call quality

If you buy a mobile phone in a shopping mall, you will generally provide a live trial phone with your own SIM card. Call a landline and ask the other party how the call quality is, whether the voice is clear, whether there is noise, and whether the volume drops suddenly.

(6) Check the usage records

After buying a mobile phone, first look at the status of storage space such as mobile games, short messages, phone books, call records, homemade ringtones and pictures and videos to see if there are any records left in these items. If so, then this mobile phone is definitely not brand new.
