Hello, it is best to go to their store to take a look when purchasing. It is better to compare several companies

First enter *#92702689# to check the call time, which shows zero calls;

Enter *#0000# to check the software version, the first line represents The software version of the phone, the second line shows the date when the software was written to the phone, and the third line indicates the model of the phone. (As the software is upgraded, the numbers also change)

Looking at the origin of the Nokia mobile phone, it shows the IMEI number *#06#

10 Made in Finland

30 Made in Korea

08 Made in China

The Asia-Pacific version is mostly made in Singapore and Made in Korea.

Hong Kong banks operate in Dongguan, Guangdong, Beijing and Tianjin, and export goods to the mainland.

Take off the battery and look at the sticker on the fuselage:

Mainland licensed products: The sticker on the fuselage is in simplified Chinese, the place of origin is China, and most of it is now produced in Beijing and Tianjin

Hong Kong licensed products: The stickers on the fuselage are almost all MADE BY NOKIA. In the past, they were mostly produced in Singapore (but those marked MADE BY NOKIA may not necessarily belong to Hong Kong brands. Please see the detailed introduction below for specific identification of Hong Kong products). Now they are manufactured in Hong Kong. Some of them will be produced in Dongguan, Guangdong.

European version: The stickers on the fuselage are almost all MADE IN FINLAND

North American version: The stickers on the fuselage are all in English, but the place of production is MADE IN CHINA

In addition, there are also products produced in Mexico and Brazil, and most of them are North American versions.

Needless to say, the mainland version, but it is also a NOKIA mobile phone. I feel that there is still a difference in quality. In order to protect domestic mobile phones, mainland China has not even reached the EU No. 1 standard, while Hong Kong has already reached the EU No. 2 standard. They are both QD, made in Finland and made in China, but there is still a difference in quality, right? Therefore, buying a licensed product means spending a lot of money to buy a second-hand machine, but the extensive after-sales service is the advantage of licensed products from the mainland. However, the customer service in the mainland does not provide a warranty for the water machine, which can be seen as a kind of protectionism. The Hong Kong version of licensed products must have a Hong Kong invoice. Most mainland NOKIA customer service can provide warranty. Without an invoice, even if it is licensed in Hong Kong, it will be treated the same as parallel imports. In addition, there is a Traditional Chinese option in the settings of the Hong Kong bank, but the font problem can be solved by flashing the machine, so this identification method is almost ineffective. The simplest way is to call the NOKIA hotline and tell them your IMEM number to find out whether it is a Hong Kong-bound machine. Mainland KF has records of Hong Kong-bound machines. In addition, Hong Kong-based phones will have a small blue and white NOKIA label on the main unit and battery. The chargers sold in Hong Kong are all three-pin (British-style large plug).

European versions are generally software based on the mainland version. The signal quality and other aspects are also good. It is worth buying. The quality of the Finnish products is at least not worse than the licensed ones. I have used N NOKIA European-modified parallel products before. In terms of quality, No problem.

The signal frequency in North America is different from ours, so the signal of the North American version is not very good, and it is the least worth buying a water machine. You can tell whether it is the American version by looking at the IMEM code of the machine. The IMEM of the American version starts with 010, not the usual 35.

The easiest way to identify whether a series of batteries is genuine is to look at the black body part on the top of the BL series battery. The black body part of a genuine battery is rubber. No matter whether it is soft or hard, as long as it is rubber, it should be genuine. Fingernails can be pressed in; the black body part of the fake electric device is made of hard plastic, and fingernails cannot be pressed in at all. There are also two small pits on the front and back of the rubber.

The keyboard recognition method in the middle of 1 is the European version. The @ position on the upper right side of the 1 button indicates Hong Kong Bank or the Asia-Pacific version.

The Hong Kong bank keyboard and the Asia-Pacific retail version keyboard are the same.

Some European keyboards do not have Chinese strokes, and some have Chinese strokes engraved on them.

1. Mobile scheming: The so-called scheming refers to a mobile customized machine with several firmware programs installed in advance, which takes up both memory and space.

2. General machine: It is the so-called licensed machine, and you can enjoy three guarantees from customer service.

3. Hong Kong bank: Hong Kong licensed products. Since NOKIA now implements joint warranty in the Greater China region, Hong Kong bank machines can enjoy joint warranty in mainland China only with a valid purchase certificate.

4. Parallel imports: Products that flow into the mainland through smuggling and have not passed the certification of the Ministry of Information Industry, and do not have network access licenses and quality assurance certificates.

5. Water-modified phones: The outside world usually refers to this type of mobile phones as authentic parallel imports. This type of mobile phone was originally sold to Europe and the United States, but was smuggled into the mainland. By translating its English software into Chinese software (adding a Chinese character library), it became a mobile phone that supports Chinese for sale

6. Original parallel imports: Generally from European countries, usually English machines, upgraded to Simplified Chinese through software.

7. Refurbished machine: Refers to using a second-hand mobile phone to replace the casing and pretending to sell it as a brand new machine. The quality is very poor. In fact, it means collecting the original movement, casing or outer packaging for repair or processing, and then treating it as a new machine. Sell. There are many types of them. The main ones are: firstly, old machines with circuit board problems are repackaged and sold after repair or parts assembly. The performance of such machines is the most unstable; secondly, the shell of normal old machines is processed or replaced. Sold new; thirdly, machines through informal channels are refreshed and repackaged through software and sold as new. Generally, the stability of the software of such machines is lacking.

8. Recharge a new phone: Handle a phone that is close to brand new and sell it as a brand new phone.

9. Board machine: A machine assembled with spare parts. Generally, its lifespan does not exceed one month.

As mentioned above, the machine software of Xinshui, Hong Kong and Pure Water is good and has no bugs. From the outside, the machine buttons have Chinese strokes, while the European version of the machine No, from the perspective of booting, the licensed version is in Simplified Chinese, the Hong Kong version is in Traditional Chinese, and needless to say, the European version must be in English or other countries' languages. What you need to pay attention to is refurbishment, recharge and trigger.

Let me talk about the identification of refurbished machines:

1. First of all, we must get rid of a misunderstanding. The most common thing people look for when buying a machine is *#06# to distinguish the place of origin. The seventh and eighth digits of the code indicate the country of origin of the mobile phone. Nokia's codes are as follows:

20: Germany;

30: South Korea;

40: Beijing;

However, new Nokia mobile phones no longer use this number to distinguish the place of origin. Enter # 06 # in the standby state of the mobile phone, and the string of numbers displayed on the mobile phone is its motherboard serial number. Write it down; remove the battery from the machine and look at the white label on the back of the fuselage. The serial number on the white label is the chassis serial number. The other label is usually the network access license. Is it consistent with the previous number? Look at the IMEI number on the box of the machine and compare the three to see if they are consistent. If the motherboard serial number and the chassis serial number are inconsistent, then the machine is likely to have been repaired or assembled from parts, and you must not buy it. If the three serial numbers are consistent, and there is a network access license, it can basically prove that the machine is genuine, but it cannot be 100% sure, because the current JS can fake anything, and the motherboard serial number can be obtained using a computer and software. Flashing, fake serial number labels and network access licenses can be bought for a few dollars. To be cautious, you should continue to verify according to the following method.

2. Many people who have used Nokia machines will also know a command, which is to enter *#92702689# in standby mode. However, this command is entered in Nokia s40 machine standby mode to enter the engineering mode of the machine. ~ Among them, Life Timer represents the total talk time of the machine ~ and Repaired represents maintenance information, etc. ~ But this command is invalid on Nokia s60 machines.

3. Check carefully whether there are scratches on the battery lock of the fuselage, whether there are wear on the SIM card slot and contacts, and whether there are marks on the MMC card contact points. It should be bright when new.

4. Look at the outer packaging and instructions of the machine: the packaging and instructions of regular new machines are beautifully printed, mostly on coated paper, with very clear fonts and images with a sense of hierarchy, while the packaging boxes of fake ones are mostly It is a simple imitation of single-sided paper, the fonts and images are very rough, and the printed handwriting is blurred. Many modification instructions from informal channels are even copied.

Although some refurbished machines use the original packaging box and manual, the machine is old after all, and the packaging box must have wear and tear, and the manual must also have signs of use. Pay more attention when purchasing and you will be able to find out.

5. Look at the network access license: There is a watermark on the real network access license, and the surface color is uneven, dark and light, thick and thin; while the fake ones are mostly copied, and the surface color does not change. . If you can't see it, you can also use a banknote detector to take a picture of the network access license. If there is an anti-counterfeiting pattern inside, it will show a red "CMII" pattern. The fake pattern is blurry. Genuine network access licenses are usually printed with dot matrix printers, and the numbers are clear. If you look carefully, there are dents made by the pins, while fake network access licenses are printed with ordinary printers, and the numbers are not very clear and there are no dents. Generally speaking, it is difficult to fake network access licenses because the equipment required for counterfeiting is relatively high in cost. In addition, you can also check the authenticity of the network access license by searching online, which will not be explained in detail here.

6. Look at the mobile phone case: When you open a new phone, you will obviously notice that there are films on the "key parts" of the phone for key protection, such as the internal screen, external screen, camera, etc. , as long as these parts come into contact, fingerprints will be left. When you see the fingerprint on your new phone, don’t listen to JS’s explanation. In addition, dust and traces of use are also unavoidable in refurbished machines. The gaps between the upper and lower shells of the machine (generally about 1MM), the gaps around the keyboard, and the charger slot are all places where dirt can easily hide. There will also be traces of use on the hinge of the flip-top machine, so special attention should also be paid to it. The casings used in refurbished machines are usually imitations of the original ones, or the old casings are carefully processed. Therefore, the front and rear parts of the machine casing are prone to not closing tightly and leaving large gaps. The identification method is to try it with your fingernails. Can it be inserted into the seam between the upper and lower covers of the phone? If so, the case is assembled. For the machine that has not had its shell replaced, JS sprayed it with a spray like detergent before selling it, and the surface of the old shell immediately had a matte effect like a new one. If you don't look carefully, you will be fooled by JS, but It won't take long for the spray paint on the casing to come off. Be sure to carefully observe the casing when purchasing, because no matter how good JS's craftsmanship is, it is not as advanced as the original equipment. If you look carefully, you can see a few small particles. Dust, caused by not working in a vacuum room when painting. If it is a flip machine, you can also check the joint of the flip cover, because sometimes, no matter how well JS handles the surface of the machine, there will inevitably be some traces of dust left in these places. Also check whether the screws on the fuselage are brand new and whether there are any signs of being turned by a screwdriver. What's more important to note is that many new mobile phones have a distinct sandalwood scent, while old phones and shell-replacement machines generally don't have such a smell, or have odors left during processing, while new phones will have a sandalwood scent. It is different from ordinary detergents and perfumes. There should be no sticky wax or oil on the body (if there is any, it has been beautified by JS).

7. Look at the screen stickers: The brand new ones should be well affixed, without bubbles or anything, and should be integrated.

8. Look at mobile phone accessories: New phones from regular manufacturers have a full set of original accessories and at least one battery and one charger. The accessories of refurbished mobile phones are generally not complete or not original. Before purchasing, it is best to go to relevant websites to find out what the standard original accessories are, so as to prevent JS from deducting accessories. In addition, if there are scratches on the matching charger and earphone plug, the old phone must have been charged, and you can still see the difference. Check if the earplugs of the mobile phone are blackened. If so, they may be refurbished or used by others. Passed.

9. Look at the records: Check whether there are any records of games, text messages, phone books, call records, self-made ringtones, WAP and voice functions and call records in the mobile phone. If so, If so, there is a strong suspicion of renovation. In addition, during normal use, if the phone frequently automatically shuts down or crashes, it can be said with certainty that there is a certain problem with the motherboard or software of this phone.

10. Check the warranty: Ask the dealer about the warranty period of the machine and ask for a formal invoice. Refurbished mobile phones cannot enjoy all the rights and interests stipulated in the "Three Guarantees" of regular mobile phones, so they generally have no warranty period or a relatively short warranty period. If the seller says that they are responsible for the warranty, they cannot agree, because regular mobile phones are generally covered by a nationwide joint warranty.

If the seller can't do this, there must be something wrong with the phone.

11. Check the price: Before buying a phone, it is best to check the price of the phone in the local newspaper or website. If the price quoted is very cheap, be wary of it. This is "cheap" Most of the mobile phones are either refurbished phones, products from informal channels, or the accessories are lacking.

Identification of batteries, chargers, and headphones:

1. The color of the original battery pack is darker and is matte paint, while the color of the assembled battery is brighter because of the middle Contains phosphor.

2. There is a small dot next to the contact of BL-5C in the original battery, but not in BL-4C. This is very important, please pay attention to it.

3. When buying batteries, you can push the edge of the packaging skin with your fingernails. The original battery will not peel, but the assembled battery will certainly.

4. The contact color of the original battery is matte and not bright, and the battery will have scratches after one use.

5. Generally, for licensed mobile phones sold in mainland China, the labels on the batteries are printed in Simplified Chinese. However, since many parallel-imported batteries are sold to foreign countries, the labels on the batteries are all in English. . Some sellers use fake batteries instead of real batteries with Chinese characters printed on them. However, the workmanship of the fake battery is very rough, while the real battery has a neat appearance without unnecessary burrs. The outer surface has a certain roughness and feels comfortable, and the inner surface feels smooth. Fine longitudinal scratches can be seen under the light. Moreover, the real battery label has clear writing, a battery label corresponding to the battery type, the marked manufacturer's font outline is clear, the anti-counterfeiting mark is bright, and it looks three-dimensional.

6. The price of original electricity is generally not less than 100, so be careful if the price is low. Nokia earphones are different from ordinary earphones. Be optimistic about the quality when buying. Genuine earphones are very fine in workmanship. Much has been said above, but there are a few things you should pay attention to when purchasing:

1. Test machine: Sellers will often allow you to test the machine, and will usually give you a fee card to allow you to test the machine. To make toll-free calls, remember not to use their card at this time. Use your own card to play the call to your friend to try the call quality. Be sure to try more and longer, and check all aspects of the machine. Problem or not, once you leave the counter, it's a hassle to change the machine.

2. When testing the machine, remember to take a completely black photo, or you can use your hand to cover it and take a completely black photo to see if there are any bad pixels on the screen. The dots are divided into many colors and will keep shaking. Although it does not affect the use, your screen will not last too long.

Laodan fried rice. (Same as above)

There are a lot of mistakes, just point out one or two points

“Some European keyboards do not have Chinese strokes, and some Chinese strokes are engraved on them.”

The European version's customs entry strokes are all uniformly engraved by Shenzhen laser

"Hong Kong Bank: Hong Kong licensed goods. Since NOKIA now implements joint warranty in the Greater China region, Hong Kong Bank machines can only be purchased with a valid purchase certificate. All mainland China can enjoy joint guarantee. "Except KF in Guangdong area, which is easier to talk to and can accept machine-printed invoices. Many of them are cloned tickets, and many KFs need to provide invoices for round-trip travel. The really effective way is to check the serial number as long as it is indeed a Hong Kong bank. You can confidently tell KF that the machine was given by your HK friend and ask him to check the serial number. As long as the machine is indeed under warranty, the warranty can usually be guaranteed (the specific operation depends on personal language skills)

3 "Original parallel imports: generally from European countries, usually English machines, upgraded to Simplified Chinese through software.

"

The European version of parallel imports usually uses a flash box, commonly known as "Golden Dog Silver Dog", to rewrite the language package and data package through the flash line instead of any software upgrade

4" The price of original batteries is generally not less than 100. Except for some relatively rare batteries such as 3230 5B and 3250 BP6M, there are generally no original batteries higher than 100. If you use price to measure whether the battery is original, I am afraid it is only more than 200 in KF. Only a single battery can be regarded as original electricity

5 "But new Nokia mobile phones no longer use this number to distinguish the place of origin. Enter # 06 # in the standby state of the mobile phone, and the mobile phone will display a string of The number is the serial number of the motherboard, write it down; remove the battery and look at the two labels on the back of the fuselage. The serial number on the white label is the chassis serial number, and the other label is usually the network access license. It is consistent with the previous number; look at the IMEI number on the machine packaging box and compare the three to see if they are consistent. If the motherboard serial number and the chassis serial number are inconsistent, then the machine is likely to have been repaired or assembled with parts. Don’t buy it.”
