This article will start with the details of buying a mobile phone and provide you with instructions on buying a mobile phone.

Find out the function of the mobile phone before buying it.

When buying a mobile phone, you must know the exact function of the mobile phone, and don't be confused by the specious words in the advertisement. The special functions of some mobile phones are not as magical as advertised by manufacturers. Such as voice-activated dialing function. Some mobile phone voice dialing can only store the phone number of 10, and calling the other party's name every time is not a call. Mobile phones often take several times to respond. So it can only be regarded as a good selling point of the product.

All distributed mobile phones must have the "network access license" of the Ministry of Posts and Telecommunications and the anti-counterfeiting mark, and the anti-counterfeiting mark will display the clear pink word "CMII" under the fluorescence of the money detector.

Attachment quality assurance

Whether the type and quantity of accessories are the same as the standard configuration of the manufacturer's franchise stores, whether the batteries and accessories are original from the manufacturer, and whether the distributor has quality assurance or corresponding written warranty commitment.

Whether the types and quantities of accessories such as charging stand are complete, whether they are original by the manufacturer, and whether the power plug meets the China standard.
