2, general machine: the so-called licensed machine, enjoy three guarantees in customer service.
3. Hong Kong banks: Hong Kong licensed products. Since Nokia now carries out joint guarantee in Greater China, Hong Kong airlines can only enjoy joint guarantee with valid purchase vouchers in the Mainland.
4. Parallel imports: products that have entered the mainland through smuggling and have not passed the certification of the Ministry of Information Industry, and have no network access license and quality guarantee.
5, water reform machine: the outside world usually calls this kind of mobile phone genuine parallel imports. This kind of mobile phone was originally sold in Europe and America and smuggled into the mainland. By translating its English software into Chinese software (adding Chinese fonts), it becomes a mobile phone sales that supports Chinese.
6. Original parallel imports: generally from European countries, usually English machines, upgraded to simplified Chinese through software.
7. Refurbishment machine: refers to selling the second mobile phone with the shell replaced as a brand-new machine with poor quality. In fact, it is to collect the original movement, shell or outer packaging for maintenance or processing, and then sell it as a new machine. There are many kinds, mainly an old machine with a circuit board problem, which is repackaged and sold after maintenance or parts assembly, and its performance is the most unstable; Second, the shell of the normal old machine is sold as a new one after being treated or replaced; Thirdly, informal channel machines are sold as new products after being refreshed and repackaged by software, which lacks the stability of the general software of such machines.
8. Charger: The color is close to the brand-new mobile phone, and it will be sold with a brand-new machine after processing.
9. Trigger: A machine assembled from parts, with a general service life of no more than one month.
The software, new machine, Hong Kong bank and pure water mentioned above are good, and there are no bugs. From the appearance, licensed and Hong Kong banks have Chinese strokes on the keys of the machine, but the European version does not. From the start, licensed Chinese is simplified, while the European version is traditional. Needless to say, it must be English or other countries. Attention should be paid to renovation, charging machine and trigger machine.
Let me talk about the identification of refurbished machines:
1 First of all, we have to get out of a misunderstanding. What people often look at when buying machines is *#06# to distinguish the place of origin. The seventh and eighth codes of the serial number indicate the origin of the mobile phone. Nokia's code is as follows:
10: Finland;
20: Germany;
30: Korea;
40: Beijing;
60: Dongguan,
However, the new Nokia phones no longer use this number to distinguish the place of origin. When the mobile phone is in standby mode, enter # 06 #, and a string of numbers displayed by the mobile phone is the serial number of its motherboard, so write it down; Remove the battery of the machine and look at the serial number on the white label in the two labels behind the fuselage, that is, the serial number of the casing. The other label is usually the network access license. Whether it is consistent with the previous figures; Look at the IMEI number on the box of the machine and compare the three to see if they are all consistent. If the serial number of the motherboard is different from the serial number of the chassis, then the machine is probably repaired or assembled, so don't buy it. If the three serial numbers are the same, plus the network access license, it can basically prove that the machine is genuine, but it can't be 100% sure, because JS can fake everything now, the serial number of the motherboard can be written by computer and software, and fake serial number labels and network access licenses can be bought for a few dollars. In order to be cautious, we should continue to verify from the following aspects.
2. Many people who have used Nokia machines will also know a command, that is, the command of standby input *#92702689#, but this command means that Nokia s40 machine can enter the engineering mode of the machine ~ where Life Timer stands for the total talk time of the machine, Repaired stands for maintenance information, etc. ~ But this command is invalid on Nokia s60 machine.
3. Look carefully at the battery lock of the fuselage for dial marks, whether the sim card slot and contacts are worn, and whether the contacts of MMC card are printed. Brand-new batteries should be bright.
4. Look at the packaging and instructions of the machine: the packaging and instructions of the regular new machine are beautifully printed, mostly on coated paper, with clear fonts and images, and a sense of hierarchy, while the counterfeit packaging boxes are mostly copied on simple one-sided paper, with rough fonts and images, blurred printing handwriting, and many instructions modified by informal channels are even copied. There are also some refurbished machines that use original packaging boxes and instructions, but after all, the machine is old, the packaging boxes must be worn, and the instructions must have traces of use. You can find it when you buy it.
5. Look at the network access license: there is a watermark on the network access license, and the surface color is uneven, with deep and shallow, thick and thin; Most of the fakes are imitations, and the surface color has not changed. If you can't see it, you can also use the money detector to look at the network access license. Is there really an anti-counterfeiting pattern in it? It will present a red "CMII" pattern. The false pattern is blurred. The real network access license is usually printed with a stylus printer, and the figures are clear. Look carefully at the dent caused by the pin, but the fake network access license is printed by an ordinary printer, the number is not very clear, and there is no dent. Generally speaking, it is difficult to fake the network access license, after all, the equipment cost required for fraud is relatively high. In addition, you can also check the authenticity of the network access license through online inquiry, which will not be explained in detail here.
6. Look at the shell of the mobile phone again: when you open the new mobile phone, you will obviously notice that the "key parts" of the mobile phone are covered with film for key protection, such as the inner screen, the outer screen and the camera. As long as these parts touch, they will leave fingerprints. Don't listen to JS's explanation when you see the fingerprints on the mobile phone. In addition, dust and traces of use are inevitable when renovating machines. The gap between the upper and lower casings of the machine (generally around 1MM), the gap around the keyboard, and the charger slot are all places that are easy to "hide dirt and shelter dirt", and the rotating shaft of the clamshell machine will also leave traces of use, so special attention should be paid. Generally, the shells used in refurbished machines are original or carefully processed old shells, so the front and rear parts of the machine shell are easy to close loosely and have a large gap. The identification method is to try to insert your fingernail into the seam between the upper and lower covers of your mobile phone. If it can be inserted, it is to assemble the shell. For the machine without replacing the shell, JS uses a mist similar to detergent before selling, and the surface of the old shell immediately appears a matte effect similar to that of the new machine. If you don't look carefully, JS will get by, but it won't take long for the paint on the shell to fall off. When buying, you must carefully observe the shell, because JS technology is no matter how good it is, and it is not as advanced as the original equipment. If you look carefully, you can see a small particle. It's dust, which is caused by not working in a vacuum room when painting. If it is a clamshell machine, you can also check the seams of the clamshell machine, because sometimes, even if JS handles the surface of the machine well, these places will inevitably leave some traces of dust. In addition, check whether the screws of the fuselage are brand new and whether there are any traces of screwdriver screwing. More importantly, many new mobile phones have obvious sandalwood smell, while old mobile phones and shell changers generally do not have this smell, or the smell left during processing, while new phones will have sandalwood smell, which is different from ordinary detergents and perfumes. The body can't have sticky wax and oil (if there is, it is beautified by JS).
7, look at the screen sticker: the brand-new one should be posted very well, there are no bubbles anywhere, one integrated mass.
8, look at mobile phone accessories: regular manufacturers of new machines have a full set of original accessories, at least one charge. The accessories of refurbished mobile phones are generally incomplete or not original. Before buying, it is best to go to the relevant website to find out what the original accessories are standard, so as to avoid JS buckle accessories. In addition, there are scratches on the plug of the matching charger and earphone. Generally, the old machine must have been charged, but you can still see the difference. See if the phone headset is black. If so, it may be refurbished or used.
9. Look at the records: Look at the records of games, short messages, phone books, call records, homemade ringtones, WAP and voice functions, call records and other items in the mobile phone. If so, there is a great suspicion of renovation. In addition, during normal use, the machine frequently shuts down or crashes automatically. It can be said for sure that there is something wrong with the motherboard or software of this mobile phone.
10, see the warranty: ask the dealer about the warranty period of the machine and ask for the formal invoice. Refurbished mobile phones cannot enjoy all the rights and interests stipulated in the "three guarantees" of regular mobile phones, so there is generally no warranty period or a short warranty period. If the seller says they are responsible for the warranty, they can't agree, because regular mobile phones are generally guaranteed nationwide. If the seller can't do this, then there must be something wrong with the mobile phone.
1 1. Look at the price: Before buying a mobile phone, you'd better find out the price of the mobile phone in the local newspaper or website. If the quotation is very cheap, be on your guard. Such a "cheap" mobile phone is either a refurbished mobile phone, an informal channel product, or an accessory that is "short of weight".
Identification of batteries, chargers and earphones;
1. The color of the packaging cover of the original electric appliance is dark, and it is matte paint. The assembled electrical appliances are bright in color because they contain fluorescent powder in the middle.
2. There is a small point beside the contact of BL-5C, but BL-4C does not. This is very important, please pay attention.
3. When you buy a battery, you can push the edge of the packaging skin with your nails. The original electricity will not be stripped, and the group electricity will definitely.
4. The contact color of the original battery is sub-light. If it is not bright, the battery will be scratched once used.
Generally, the labels on licensed mobile phones sold in Chinese mainland are printed in simplified Chinese, while many parallel batteries are sold abroad, so the labels on them are all in English. Some sellers use fake batteries instead of real batteries, and the real batteries are also printed with Chinese. However, the fake battery is very rough in workmanship, while the real battery has a neat appearance and no redundant burr. The outer surface has a certain roughness, and it feels comfortable. The inner surface feels smooth, and subtle longitudinal scratches can be seen under the light. Moreover, the handwriting of the real battery label is clear, the battery label corresponds to the battery type, the font outline of the manufacturer is clear, the brightness of the anti-counterfeiting logo is good, and the appearance is three-dimensional.
6. The original electricity price is generally not lower than 100. If the price is low, you should pay attention.
Nokia headphones are different from ordinary headphones. When you buy them, you are optimistic about the quality. Authentic headphones are very fine in workmanship.
That's all, but when shopping, you should also pay attention to the following points:
1. Try calling: Sellers usually allow you to try calling, but they usually give you a free calling card. Remember not to use their cards at this time, and use your own cards to call your friends to try the call quality. Be sure to try more. If you try for a long time, check all aspects of the machine for problems. Once you leave the counter, it is troublesome to change opportunities.
2. When testing the machine, remember to take all-black photos, or take all-black photos by hand to see if there are any bad spots on the screen. This bad spot is divided into many colors and will keep shaking. Although it won't affect the use, your screen won't last long.
