What do you look for when buying a mobile phone?

Look at the IMEI serial code: each mobile phone has its own unique ID number: IMEI number, on the outer packaging box, on the back cover (or in the battery slot), and there will be a unified (ID number) IMEI in the three places of the mobile phone motherboard.

The IMEI serial number of all mobile phone motherboards is displayed on the mobile phone screen after dialing "*" on the keyboard. Remove the phone battery and read the IMEI serial number in the white label on the back of the phone. After the two IMEI serial codes are seen, they are compared with the serial numbers on the mobile phone packaging box, and if it is a unified serial code, it proves that this mobile phone is basically a **mobile phone.
