First, check the appearance quality of the product. For example, the genuine shell material should be strong and not easily damaged, and the outer surface of the power supply should be uniform in color, clean, and free of scratches and mechanical damage.

The second is to check the mobile phone network access sign. According to national management regulations, mobile phones must obtain the network access mark before they can be sold. The network access logo is usually affixed to the back of the phone, which can be seen after the battery is removed. Under purple light, there will be a "CMII" logo that is larger than the original words. You can also directly enter the network access license number (the first line of the network access permission mark), the scrambling code (the third line of the network access permission mark) and the mobile phone number (the dialable number "＊#0６#" posted on the mobile phone "Obtain) and enter it one by one, this website will tell you the authenticity of the phone. If you have difficulty accessing the Internet, you can call (010) 82058767 and 82050313 for manual enquiry. In addition, you can also use mobile phone text messages for identification. You only need to send "RW#network access certificate number#scrambling code#mobile phone number" to 9500, and the telecommunications equipment network access certification management information system will automatically reply with identification information.

Authenticity of mobile phone

Verify. Among them, "RW" is a fixed code, and "#" can be replaced by spaces.

The third is to check the mobile phone packaging. The package should contain the product name, factory name, factory address, contact number, production date, instructions, list of accessories, implementation standard code, serial number, network access certificate number, corporate standard (trademark), model, specification logo and laser anti-counterfeiting mark, fuselage Corresponding barcode to the packaging, etc. Mobile phones produced overseas should have Chinese origin, agent name, network access certificate number, instructions, accessory list, warranty certificate, etc.

The fourth is to check the IEMI code of the mobile phone. For GSM digital mobile phones, just press "＊#06#" in sequence to display the phone's IEMI code on the phone screen (which can be seen after removing the battery), which is consistent with the IEMI code on the packaging box and the IEMI code on the warranty card.

The fifth is to search online. By logging into the China Mobile Communications Industry Network, consumers can check whether it is a "registered" regular product by providing information such as the province where the mobile phone was purchased, time of purchase, brand, model, mobile phone number, etc.

At the same time, you can also identify the authenticity of the battery through the following aspects:

First, the battery casing or packaging Product identification on the label should use standardized text descriptions. The battery name, trademark or brand, model specifications, standard voltage, rated capacity, positive and negative poles of the power source, warning signs or instructions, manufacturer name or abbreviation and factory serial number, and implementation standards.

Second, the battery label uses secondary printing technology. Under certain light, when viewed from the side, it is obvious that the color of the barcode part is darker than the rest. The white part of the label surface was lightly scratched with a metal object, and there are traces similar to pencil scratches.

Third, the battery casing is made of special materials, which is very strong and not easily damaged. The battery cannot be opened by ordinary means. The appearance is neat and there are no unnecessary burrs. The outer surface has a certain roughness and feels comfortable. The inner surface feels smooth. Fine longitudinal scratches can be seen under the bulb.

Fourth, the width of the battery electrode is the same as that of the mobile phone battery. The isolation material between the battery charging electrodes is the same as the shell material, but not integrated; the corresponding positions below the battery electrodes are marked with "+" and "-" marks, and the hardware contacts are bright and rust-free.

Fifth, when the battery is pushed into the mobile phone, it should feel comfortable and move up and down freely. The pressing part of the battery lock is in an appropriate and firm position, and is tightly integrated with the mobile phone. As far as the current range of battery usage is concerned, lithium batteries are widely used due to their good performance.

We also remind you that when buying a mobile phone, you should choose a regular, reputable store or specialty store, choose a well-known brand with clear after-sales service commitments, and pay attention to asking for a purchase voucher, which should clearly indicate the product name. Brand, specifications and models, etc., in order to provide evidence to relevant departments in case of disputes.
