How to choose a Nokia mobile phone

Remove the battery and check the body:

Chinese Mainland: The body is pasted in simplified Chinese and the origin is China Most production in Beijing and Tianjin

Hong Kong licensed: almost all of the body stickersMade by NokiaPreviously, it was mostly produced in Singapore (Made by NokiaNot necessarily belong to the Hong Kong bank. Please refer to the following details for specific identification.) Now, the Hong Kong bank has changed to production in Dongguan, Guangdong. .

European version: almost all body stickersMade in Finland

North US version: The body is pasted in English, but the origin isMade in China

In addition, there are also Mexican, Brazilian, and most of them North American.

Not to mention the Chinese version, but it is alsoNokiaMobile phones, I think there is a difference in quality. In order to protect Chinese mobile phones, the Chinese mainland now connects to the EU1And Hong Kong has reached the EU2. SameQDIs there a higher quality level for Finnish and Chinese products? Therefore, purchasing a machine for purchase costs a lot, but many after-sales services are the advantages of mainland China, but the customer service in mainland China does not provide water machine warranty, it can be seen as a type of protectionism. The Hong Kong version of the licensed goods must have Hong Kong invoices, the vast majority of Mainland ChinaNokiaThe customer service team is entitled to warranty and has no invoices. Even Hong Kong Licensed customers will be treated in the same way as normal customers. In addition, the Hong Kong bank settings will have the option of Traditional Chinese, but you can flash the machine to solve the font problem, so the identification method is almost ineffective. The simplest way is to callNokiaTo tell him your hotline.ImemYou can find out if it is a port number or a Chinese mainland.KFThere is a record of the port. In addition, the port host is on the host, and the battery is blue-white.NokiaSmall tag. The Hong Kong Licensed chargers are all three-legged (British plug ).

The European version is generally a Chinese version of the software, and the signal quality is also good, it is worth buying, the quality of Finland is at least not inferior to the licensed, I usedNDepartmentNokiaQuality is not a problem in Europe.

The signal frequency in North America is different from ours, so the signal in North America is not very good.,Is the least worth buying water machine. Check the hostImemThe code indicates whether it is a US version.ImemStart010, Not the usual35.

Next I will discuss the identification of refurbished machines:

1First, we need to get out of a misunderstanding. What you often see when buying a machine is* #06 #To distinguish the origin, the seventh and eighth digits of the serial numberCodeIndicates the origin of the mobile phone. The Nokia code is as follows:

20: Germany;

30: South Korea;

40: Beijing;

but the new Nokia the mobile phone no longer uses this number to identify the origin. The mobile phone enters the STANDBY state. # 06 #. The phone shows a string of numbers, that is, the serial number of the motherboard; remove the sub-battery and check the string number on the white label on the two labels behind the fuselage, that is, the shell string number. The other label is generally a network access license. Check whether it is consistent with the preceding number. Then, check the IMEI number in the box and compare the three to see if they are consistent. If the motherboard serial number is different from the chassis serial number, this machine is likely to be repaired or assembled by parts and cannot be purchased. If the three serial numbers are the same and you have a network access license, it will basically prove that this machine is genuine, but it cannot be totally affirmed, because the current JS counterfeit everything, the motherboard serial number can be written in a computer or software, fake serial number tags and network access licenses can be purchased for a few dollars. For the sake of prudence, you should continue to verify the Code as follows.

2Many people who have used Nokia machines will also know a command, that is, standby input.* #92702689 #This command, but this command is NokiaS40Machine standby input this command~Enter the engineering mode of the machine~WhereLife TimerIndicates the total call time of the machine.~WhileRecyclredIndicates repair information, etc.~But this command is available in NokiaS60Are invalid.

3Carefully check whether there are dial marks at the battery lock on the fuselage,SimGroove and contacts are worn out,MMCWhether there are marks on the snap-on contacts. The brand new one should be bright.

4Look at the machine packaging and manual: Regular new machine packaging and manual printing exquisite, mostly for copper paper printing, fonts and images are very clear, have a sense of excitement, the fake packaging box is mostly made of simple single-sided paper. The fonts and images are rough, and the printing handwriting is blurred. Many non-formal conversion manuals are even copied. There are also some refurbished machines that use the original genuine packaging box and instructions, but after all the machines are old, the packaging box must be worn out, the instructions must also have traces of use, pay more attention to the purchase and you will be able to find out.

5Check the network access license: There is a watermark on the network access license, the surface color is uneven, there is a deep and shallow, there is a thick and fine; while the false is mostly copies, the surface color is not changed. If you cannot see it, you can also use the money detector to take a picture of the inbound license. There is a real anti-counterfeit pattern in it. The red"Cmii. Fake patterns are blurred. The real network access certificate is usually printed with a dot matrix printer, the number is clear, carefully look at the concave marks of the needle, and the false network access license is printed by a general printer, the number is not very clear, there is no dent. In general, it is difficult to fake a network license. After all, the equipment required for counterfeiting is relatively high in cost. In addition, you can query the Internet to verify the authenticity of the network access license, which is not described in detail here.

6 Watch the mobile phone shell: When you open a new machine, you will obviously notice that the "key parts" of the machine have a film for protection, such as internal screen, external screen, camera head, etc, as long as these parts are exposed, fingerprints will be left. when you see the fingerprint on the new machine JS Do not listen to the explanation. In addition, the dust and usage marks are also difficult to avoid from the new machine, and the gap between the upper and lower case of the machine (generally 1 MM Left and right), the gaps around the keyboard, and charger slots are easy to "Hide dirt", and the rotating shaft of the flip host will also leave traces of use, also pay special attention. The General Shell of the refurbished machine is made of imitation original, or the old shell is carefully processed, so it is easy to close the two parts before and after the chassis, it is easy to keep a lot of seams, the identification method is to use the fingernails to try whether to insert the seams on and off the mobile phone. If it can be inserted, it is to assemble the shell. For a device without a shell replacement, JSBefore the sale, use a kind of detergent-like mist spray, the surface of the old shell immediately shows a frosted effect like a new machine, if not carefully checked, will be JS But it won't take long for the shell to be painted. When buying the shell, you must carefully observe the shell, because JS The process is good, and there is no advanced equipment from the original factory. If you look at it carefully, you can see a little small particles. It is dust, because there is no paint In a vacuum room. If it is a flip machine, you can also check the combination of the flip, because sometimes, even if JS When the machine surface is well processed, it is inevitable to leave some dust marks in these places. In addition, check whether the body screws are brand new and whether there are any traces of screwdrivers being screwed. It should be noted that many new mobile phones have an obvious sandalwood flavor, and the old and shell-changing machines do not have such a smell, or the odor left by working hours, the new machine will taste Sandalwood , Different from general detergents and perfume flavors . The body cannot contain sticky wax and oil. ( If yes JS Beauty now ).

7Watch screen Stickers: brand new stickers should be well pasted, with no bubbles, all in one.

8Watch mobile phone accessories: Regular manufacturers of new machines have a full set of original factory accessories, at least one power and one charge. The accessories for refurbished mobile phones are generally incomplete or not from the original manufacturer. before purchasing a mobile phone, it is best to go to the relevant website to learn about the standard factory accessories, so as to prevent beingJSBuckle accessories. In addition, check that there are scratches on the matching charger and the plug of the headset. Generally, the old machine must be fully charged. You can still see the difference. Check whether the ear plug of the mobile phone is black, if yes, it may have been refurbished or used.

9Viewing records: You can view games, text messages, phone books, call records, self-edited ringtones,WAPThere are no records used in projects such as voice functions and call records. If there are any records, there may be very large retries. In addition, during normal use, the host automatically shuts down or crashes frequently, so you can say that the motherboard or software of this mobile phone has some problems.

10View Warranty: Ask the dealer about the warranty period and ask for a formal invoice. Refurbished mobile phones cannot enjoy all the benefits stipulated by the regular "three-pack". Therefore, there is generally no warranty period or the warranty period is relatively short. If the seller says they are responsible for the warranty, they cannot agree, because regular mobile phones are generally provided by the National warranty service. If the seller cannot do this, there must be problems with the mobile phone.

11Watch the price: before purchasing a host, you 'd better know the price of your mobile phone in a local newspaper or website. If the price is very cheap, be cautious, in this way, "cheap" mobile phones are neither cell phones or non-formal channel products nor accessories ".

Battery, charger, and earphone identification:

1The color of the original electric packaging skin is relatively dark, it is matt paint, the color of the assembled electricity is relatively bright, because the middle contains phosphor.

2, Original power inBL-5CThere is a small dot next to the contact,BL-4CThis is very important.

3When buying a battery, you can use a nail to push the edge of the wrapped skin. The original power won't start skin, and the group power will definitely be.

4The contact color of the original power is Matt, but it is not bright. There will be scratches when the battery is used once.

5For licensed mobile phones sold in mainland China, the labels on batteries are printed in simplified Chinese, while many of them are sold in foreign countries, so the labels are in English. Some sellers use fake batteries to replace real batteries, which are printed in Chinese. However, the work of the fake battery is very rough, while the real battery looks neat, there is no extra glitch, the outer surface has a certain roughness and comfortable feel, the internal surface feels smooth, fine Vertical Scratches can be seen under the light. Moreover, the battery labels are clearly written, and the battery labels correspond to the battery type. The labels are clear in the fonts of the manufacturers, and the anti-counterfeit labels have a good brightness and look like they are stereoscopic.

6The price of the original power is generally not lower100If the price is low, pay attention to it. Nokia headphones and general headphones are different, when buying good quality, genuine headphones work very fine. The above describes how many items are used, but you should pay attention to the following points during the purchase:

1Try-out: the seller will often agree to your try-out, but will usually give you a card for you to call for free and so on. Remember not to use their card at this time, you can use your own cards to play a call to your friends. You must try the call quality more. You must also try the call for a long time to check whether there are any problems with all aspects of the machine. Once you leave the counter, it is very troublesome to change the machine again.

2Remember to take a full black photo during the test, or you can take a full black picture on your hand to see if there are any bad points on the screen. This bad point is divided into many colors, it will remain jittery, although it does not affect the use, but your screen will not be used too long.
