Let's take a look at this.

Parallel imports, licensed goods and second-hand goods have always been a problem that puzzles users in purchasing goods. For mobile phones, parallel imports, licensed goods and fakes have more choices, and they are also familiar topics. In fact, all these "three goods" have users who like it. What we have to prevent is that users who want to buy licensed goods buy parallel imports or fakes, so the losses will be great. Therefore, it is necessary to teach you some general identification skills, so that you can identify parallel imports, licensed goods and fakes.

first, what are parallel imports, licensed goods and counterfeit goods

let's first understand the three concepts of parallel imports, licensed goods and counterfeit goods in mobile phones, which is very beneficial for us to identify and purchase.

licensed products refer to products produced by the original factory and directly sold by dealers, agents or specialty stores. Licensed goods are genuine goods, which have been tested and approved by the telecommunications department and have access licenses.

parallel imports-usually refer to products from foreign countries, Hong Kong, Macao and Taiwan that have not entered the domestic market through normal customs channels. The main purpose of this product is to avoid paying taxes, or the product has been improperly modified and cannot enter the customs through normal channels. Parallel imports do not rule out that they are original goods, but they cannot rule out that they are modified inferior goods, and this product is basically not guaranteed by domestic manufacturers, so it is still very unsafe to buy parallel imports. Therefore, consumers should resolutely resist when buying and buy legal products in the market.

Fake-as the name implies, it is usually made by modifying other models of mobile phones, replacing chips and so on. There is also a Chinese machine, that is, an English machine is turned into a Chinese machine. After all, this machine is not a real Chinese machine, and there are various problems.

We have noticed here that what we are most afraid of is buying fakes in the process of buying mobile phones. In this case, the mobile phone you want to buy is definitely very different from the one you bought, and there is a problem whether it can be used normally, which is meaningless. So, how can we distinguish whether it is licensed, parallel or fake?

Second, the identification method is quick to get started

Because there are too many models and styles of mobile phones in the mobile phone market at present, it is really difficult for ordinary consumers to find some parallel imports and fakes. Fortunately, some experts have provided us with the following new methods of mobile phone identification, so you might as well give it a try!

1. surfing the internet, making a phone call or sending a text message will do.

I'd like to tell you a piece of good news. The China Ministry of Information Industry's telecom equipment network access authentication management information system has been opened. Consumers can access this system through the Internet or make phone calls and send text messages to identify the authenticity of mobile phones.

first of all, consumers can visit the telecom equipment access authentication network (www.tenaa.com.cn), select "online service"-"logo verification" (/FlagValidate.aspx), and then input the access authentication number, scrambling code and mobile phone body number (obtained by dialing the number "* # 6 #") posted on the mobile phone one by one, and this website will tell you the authenticity of the mobile phone.

If you are inconvenient to surf the Internet, you can call (1)8258767 and 825313 for manual inquiry. In addition, you can also use mobile phone short messages for authentication. You only need to send "RW # network access certificate number # scrambling code # mobile phone body number" to 95, and the telecommunication equipment network access authentication management information system will automatically reply an authentication message to verify the authenticity of the mobile phone. Where "RW" is a fixed code and "#" can be replaced by spaces. These methods are very convenient to use, so you may wish to try them when shopping.

2. Five main points of purchasing a mobile phone

In fact, through careful observation, we can find some "clues" from the newly bought mobile phone, so as to know whether the mobile phone is genuine or not. The following are some aspects that need attention:

① Check the appearance quality of the mobile phone, such as the shell material of the genuine mobile phone should be firm and not easy to be damaged, and the outer surface of the power supply should be uniform in color, clean and free from scratches and mechanical damage.

② Check the mobile phone network access sign. According to the national regulations, mobile phones can only be sold after obtaining the network access sign, which is generally posted on the back of the mobile phone that can be seen immediately after the battery is removed.

③ Check the packaging of mobile phones. Mobile phones produced overseas should have Chinese origin, agent name, network access certificate number, instruction manual, attachment list, warranty certificate, etc.

④ check the IEMI code of the mobile phone (which will be explained in detail below). As long as the GSM digital mobile phone presses "* # 6 #" in turn, the IEMI code of the mobile phone can be displayed on the screen of the mobile phone, which is consistent with the IEMI code on the packaging box and the IEMI code on the warranty card.

⑤ You can check online and log in to www.chinamobile.gov.cn, the mobile communication industry network of China. Consumers can check whether the mobile phone is a "registered" regular product by providing information such as the province, purchase time, brand, model and mobile phone body number.

3. Check the authenticity of the mobile phone with the identification number

How do you know that your mobile phone is not a parallel product, but a genuine one? In fact, this is not difficult. Almost all mobile phone manufacturers have designed ID inquiry programs in their mobile phone programs, and users only need to input some specific characters to check their mobile phone ID.

ERICSSON

enter "(i.e. right * left * left * left *)" in turn, and the mobile phone displays "aaaaabbbbPRGccccccccc". Among them, aaaaaa is the date of production (YY/MM/DD).

Nokia NOKIA

enter "* # #" in turn, and the message "Vxx.xx.dd-mm-yyNxx-x" will appear on the mobile phone. Vxx is the software version, dd-mm-yy is the production date (day-month-year), and Vxx.xx is the mobile phone model (for example, 331 is NHM-5). Enter "* # 6 #" to display the mobile phone ID number.

SAMSUNG

Enter "* # 9999 #" in turn, and the phone will display a string of characters. Among them, S———1999; T———2; A-January; B-February ... and so on. In addition, because Kejian mobile phones are mostly Samsung OEM products, this brand of mobile phones is also suitable for this method.

Panasonic

GD9/92 After the phone is turned on, when the phone is searching for the network, a string of data will appear by typing "* # 9999 #". Including the model, software version and production date of the mobile phone.

MOTOROLA

press "* # 6 #" to check the content of MSN (on the mobile phone label). Display: aaabcdddd

AAA is the model code. (Example: A74 —— CD 92/928; A84———L2)。

b is the origin code. (2)-Britain; 6-Tianjin; G-the United States; R-Germany).

cc is the date code. The previous C is the year (X-97; Y———98； Z———99； A —— 2), and the last "c" is the month (A, B —— 1; C、D———2； E、F———3……)。

dddd is the serial number of the product.

4. Mobile phone accessories should also be protected against counterfeiting

We know that counterfeiting of mobile phone accessories often affects the quality of the whole mobile phone, especially the mobile phone battery, and we should pay more attention to it. Consumers can identify the authenticity of the battery from the following aspects:

① Note that the product identification on the battery shell or package should use standardized words, including the battery name, trademark or brand, model and specification, standard voltage, rated capacity, positive and negative poles of power supply, warning signs or descriptions, name or abbreviation of manufacturer, factory number and implementation standard.

② Pay attention to the secondary printing technology used in the battery label. In a certain light, when viewed from the side, it is obvious that the color of the bar code part is darker than the rest, and the white part of the label surface is lightly scratched with a metal object, which has traces similar to those of a pencil.

③ Note that the battery case is made of special material, which is very firm and not easy to be damaged. The battery can't be opened by general means, with neat appearance and no redundant burr. The outer surface has a certain roughness and feels comfortable, the inner surface feels smooth, and fine longitudinal scratches can be seen under the light bulb.

④ Note that the width of the battery electrode is the same as that of the mobile phone battery piece, and the isolation material between the battery charging electrode pieces is the same as that of the shell, but they are not integrated; The corresponding position below the battery electrode is marked with "+"and "-",and the metal contact is bright and free of rust spots.

⑤ Note that the battery should feel comfortable when pushed into the mobile phone, move up and down freely, and the battery lock should be properly and firmly locked and closely combined with the mobile phone. As far as the application scope of batteries is concerned, lithium batteries are widely used for their good performance.

5. Go to a specialty store to buy

Here I remind consumers to choose a regular and reputable store or specialty store to buy a mobile phone, choose a brand with high reputation and a clear after-sales service commitment, and pay attention to obtaining a purchase voucher. The brand and specifications of the product should be clearly written on the voucher, so as to provide evidence to the relevant departments in case of disputes.

Third, learn to use IMEI codes

In fact, besides the methods described above, there is a quite general method, that is, IMEI codes. The so-called IMEI is International Mobile Equipment Identity (IMEI for short). Translated into Chinese as "International Mobile Equipment Identity Code", its biggest function is to help identify the authenticity of mobile phone identity.

1. Give play to the function of identification

As the saying goes, there are bad shops or buyers in the market who will use the origin of mobile phones to deceive people to raise or lower the price of mobile phones, which is related to whether the mobile phones are original or not, which will directly affect the value of mobile phones.

sometimes the briber holds your mobile phone, presses it a few times and says that your mobile phone is not the original one and is worthless. But when you bought the machine, the salesman said loudly that it was absolutely genuine and charged you more money. At this time, IMEI can often reveal which one is lying to you and play the role of identity recognition.

IMEI contains the model approval code and factory serial number of the mobile phone. The approval number of the same model mobile phone must be the same, but the factory serial number will never be the same. If you see that the approval numbers of two mobile PHONEs of the same model are different, or you see that the factory serial numbers of two mobile phones are the same, you phone fans will wake up. One of them must be fake. Don't make a mistake, mobile phone fans!

the large-scale deconstruction of p>IMEI is composed of 15 numbers. Press "*#6#" on your mobile phone and it will pop up. The format is 123456-78-91234-5.

123456=TYPE APPROVAL CODE, that is, the equipment model approval number.

78=FINAL ASSEMBLY CODE, that is, the final assembly number.

91234=SERIAL NUMBER, that is, the factory serial number.

5=SPARE NUMBER, that is, the spare number.

Let's demonstrate it with Nuoji 885, Moji V3688+ and Aiji GF768.

after p>Nokia 885 presses "*#6#", 44891-3-233588-9 appears on the screen, in which 44891 represents the approved model number of the mobile phone, 3 represents the last assembly place in Korea, 233588 represents the factory serial number of the mobile phone, and 9 represents the spare number.

after "*#6#" is pressed by Motorola V3688+, 448835-8-545659-6 will appear on the screen, where 448835 represents the approved model number of the mobile phone V3688+,8 represents the last assembly place in China, 545659 represents the factory serial number of the mobile phone, and 6 represents the spare number.

after p>ERICSSON GF788 presses "*#6#", 49514-51-636354- appears on the screen, where 49514 represents the approved model of the mobile phone GF788, 51 represents the last assembly place in Sweden, 636354 represents the factory serial number of the mobile phone and represents the spare number.

decoding the final assembly number of the mobile phone origin means that the mobile phone factory has completed the last production process, and each factory has a different special code. Although this code cannot be directly equated with the code of the country where the mobile phone was made, there is no difference in many people's minds. The place where the final process was completed is equated with the origin of the mobile phone. Now, we will briefly introduce the common origins of some big mobile phone manufacturers.

2. Detailed explanation of IMEI

Because the IMEI code can also reflect the "file" and "ID number" of the mobile phone in the manufacturer, the IMEI code is not only posted on the back of the mobile phone motherboard, but also reserved in the ROM of the mobile phone. When we purchase a mobile phone, we can call out the IMEI code in the memory through the "*#6#" command to see if its display is consistent with the IMEI code posted on the back, so as to distinguish the authenticity of the mobile phone and judge the origin and even the specific origin of the mobile phone. IMEI is usually a string of 15 digits, but there are exceptions now: for example, the IMEI code in the memory of Ericsson T18SC has two digits more than that on the label, and the IMEI code in the memory of Philips 828C has two digits more than that on the label. The following is a description of how to identify it with a common 15-bit IMEI code. Its format is as follows: 6 (type approval code)-2 (final assembly code)-6 (serial number)-1 (spare number), that is, 123456-78-91234-5.

①.TAC: it is the equipment model approval number, which represents the model of the mobile phone. Every mobile phone brand, such as Nokia, Ericsson or Alcatel, must have the same TAC code as long as it is the same model. For example, the TAC code of several Alcatel OT31 I have seen is 332157. Now there are illegal vendors who buy old phones from Guangdong, disassemble the movement and install a new shell for sale. We can find the clues from the differences of TAC, as long as you know the correct TAC code of this type of mobile phone, because the old models are generally older and will not be the same as the more popular models now.

②.FAC: the last assembly number, which represents where the mobile phone was finally assembled, that is, which country or region the last assembly factory was in, and generally does not go to which manufacturer, so this is not the code name of which country it was made. However, we generally regard the location of the factory where the final assembly process is completed as the origin of the mobile phone, so the FAC code can also be considered as the code of the origin of the mobile phone. Now major mobile phone manufacturers have their own production bases in China, so it is no problem to produce middle and low-grade models, so if you buy middle and low-grade products produced by these brands in foreign production bases at home, then you should be careful at this time. Because there is no domestic brand of a product that is sold so well that it is too late to produce and import. It is best to put the network access card under the money detector for verification just in case. If the network access card shows a red "CMII" pattern and a number that is not very clear, it is a formal entry.
