How to distinguish whether a mobile phone is licensed or parallel imported?

What is licensed goods?

a. Licensed goods: also called mainland licensed goods. It refers to the recognition of manufacturers that have been issued a "license" by the Ministry of Information Industry of China, and enjoys nationwide joint guarantee and three-guarantee card. Licensed goods are products that have been authorized by a merchant to be agents or are sold directly by branches of the manufacturer in a designated area. Because licensed goods require agents and their branches to obtain reasonable compensation, they must also pay a fee that meets the government requirements of the region. There are tariffs and taxes, so the price of licensed products is often higher. Because it is an official local agent, the product warranty and after-sales service are often more guaranteed.

b. Hong Kong: As the name suggests, licensed products sold in Hong Kong. There is not much price difference between genuine Hong Kong-branded mobile phones and mainland guilds, generally only about 1-2 yuan, and purely Hong Kong-branded machines can enjoy nationwide joint warranty. Different from mainland-licensed ones, Hong Kong-branded mobile phones are machine-made. *Invoice will be issued by taxi

1. What is parallel import?

Parallel import is not a professional term. Therefore there is no standard definition.

It is generally believed that smuggled goods without paying customs duties are parallel imports. In fact, this definition is not accurate either. What kind of goods are sold at auction after being seized by customs? have no idea! I think parallel imports refer to products that should not be sold in a certain country or region but are sold in that country or region, or products that are sold directly without authorized regular dealers. It has nothing to do with the place of production, only the place of sale!

Several types of parallel imports:

A. Jointly guaranteed licensed goods: Jointly guaranteed licensed goods are actually a type of parallel imports. This is just what people in the industry say; in the early days, they were licensed goods from Hong Kong, which is what everyone calls them. As for "B", the customer service will also provide warranty for this kind of mobile phone in the early stage, but then all the warranty will be cancelled. These "jointly guaranteed" products will have fake "network access permission" labels and laser anti-counterfeiting labels on them, but the major customer service companies will not be responsible for the warranty, only the dealers will be responsible for the warranty. This kind of mobile phone is exactly the same as the genuine product in appearance and packaging, and it also has a "Three Guarantees" card.

B. Hong Kong water: Hong Kong water is a new term recently, but this port water is not necessarily a parallel-imported mobile phone sold in Hong Kong. It may be a parallel-imported vending machine from the Asia-Pacific region or Japan and South Korea. However, it is transferred from Hong Kong and then sold to the mainland. Hong Kong Water does not have a national joint guarantee and has no chance to issue tickets. There is no difference between Hong Kong Bank and Hong Kong Water without nationwide guarantee. There are still very few mobile phones of Hong Kong Bank in the Mainland. , so most of the Hong Kong banks we buy are from Hong Kong water.

C. Taiwanese: Taiwanese licensed, mostly used on SmartPhone machines. There is not much difference between Taiwanese products and licensed products in appearance. Most of the keys are displayed in traditional Chinese characters, and the hardware is no different from licensed products.

D. European version: simple and clear, a machine smuggled from Europe. European version mobile phones are generally signed with various telecom companies in Europe. The principle is the same as the mobile points exchange. Vodafone and TIM are both relatively large telecom companies in Europe. They usually print their company logos. As for the phone, it is the same as the customized version of domestic mobile phones, so it is more convenient to distinguish the phone from the appearance. Water machines sold in China will be mentioned as European version, TIM version and Vodafone version. The difference is that the telecommunications companies are different. Each phone The types of phones the company represents are different, and the prices are also different, so some are high and some are low. When they are smuggled into the country, because they enter the country through abnormal channels, the sales price is quite different from that of licensed mobile phones, ranging from a few hundred yuan to more. The price ranges from several thousand yuan, and there is no difference in use from licensed products, and they do not enjoy the nationwide joint warranty.

E. Asia-Pacific version: generally refers to the Singapore version and Japanese and Korean machines. European and American brand machines in Singapore were launched early, while Japanese and Korean brand machines are generally first launched in the local market and then sold in other regions. This phenomenon is particularly serious for Korean machines, but unknown machines are always named after the Asia-Pacific version. For sale, you need to be careful when buying.

F. Malaysian version: licensed in Malaysia, mostly used on Samsung machines. The biggest fun for friends who play with Samsung machines is to flash them. Customer service will not provide warranty after flashing Samsung's mainland-licensed machines. Parallel Samsung cannot flash the licensed version, while Ma Xing's machines can be flashed. In terms of hardware, There is no difference from the licensed products in mainland China.

G. Water modification: It can also be called the European version. It is a real parallel import machine and is used on Samsung mobile phones.

These mobile phones were originally sold to Europe. Since the interface of the mobile phones was in English, it had to be changed to Simplified Chinese when sold in China. JS translated the English software into Chinese software (added Chinese character library) to make it a mobile phone that supports Chinese. Sales, but the Chinese font library will occupy part of the memory. Due to the low software of the mobile phone, there will be some minor faults in the early stage, such as crashes, inability to connect to GPRS, inability to input Chinese, etc. However, with the upgrade of the software version, these problems will disappear. can be resolved. The hardware quality of the water modification machine itself is still trustworthy, so there is no need to worry.

H. Clone machine: You will know its meaning just by looking at the name. It means COPY a series of things such as the licensed serial number and copy it to another machine. The early cloning machines were relatively poor, and some of the current cloning machines are so fake that even the workers at the maintenance point cannot tell the real ones from the fake ones.

I. 14 Tianji: 14 Tianji refers to a service launched by foreign network operators (like China Mobile and China Unicom) for customers. The content of this service is that consumers who promise to use their own network can unconditionally return or exchange the phone within 14 days of purchase for any reason, provided that the phone is not artificially damaged. In other words, no matter what the reason, as long as the consumer pays attention to the operation If you are not satisfied with the service or use of your mobile phone, you can return or exchange it unconditionally, giving consumers a 14-day usage experience and allowing them to decide whether to use the services they provide. Since these returned mobile phones have been used and can no longer be sold as new phones, they flow into our country through illegal channels. This fourteen-day machine is the most affordable in the parallel market. Since the price of 14-day phones is higher than that of second-hand phones, and the quality is very new, some JS will sell such 14-day phones as new machines or sell used or refurbished phones as 14-day phones. Be careful when purchasing.

J. Rechargeable new phone: This kind of phone is a new phone that JS recycles or a phone that is given away by some telecommunications companies in Hong Kong or other countries. In those areas, many people in those areas will use the given mobile phone as a second-hand phone after using it for a few days, and then smuggle it into the country for sale. 14-day phone is also a kind of rechargeable phone, so be careful when buying it.

K. Refurbished mobile phone: According to the mobile phone industry, this kind of mobile phone is a recycled second-hand mobile phone that is cleaned with chemical liquid, replaced with a new casing, equipped with a battery, charger and packaging and sold as a new phone. The most important thing is refurbished machines, which are prone to malfunctions.

L. Board machine: Board machine is also called assembly machine. It is a mobile phone motherboard that is assembled from non-original mobile phone motherboards or repaired mobile phone motherboards, or useful parts removed from scrapped machines. The mobile phones are assembled with shells, accessories, and repackaged for sale. They are collectively called board machines. . The trigger is the most harmful and has the risk of explosion.

2. Is there a difference between parallel imports and licensed imports?

First of all, licensed products are products that can be sold under warranty in mainland China. Parallel imports are products that can enjoy warranty abroad (it is impossible to go abroad for warranty after being smuggled in). If our licensed products are taken abroad, they will also be parallel imports!

Therefore, there is no difference in function between parallel imports and licensed imports.

3. What are the parallel imports?

Generally speaking, parallel imports are divided into Hong Kong bank (B bank), European water (water reform), Malay bank, North American version, etc.

As the names suggest, the above four types are licensed products in the above-mentioned areas! But after arriving in China, they became parallel imports.

4. Where do parallel imports come from?

As we all know, almost all mobile phone brands in the world have production plants in China. NOKIA has factories in Beijing and Dongguan, Samsung has factories in Tianjin and Shenzhen... Therefore, all licensed products are produced in China (except for a few parts of the machine). Model)

Take Samsung as an example. Before Samsung set up a production plant in mainland China, Samsung's parallel imports mainly included three types: parallel imports (made in South Korea that were smuggled in without paying tariffs), Hong Kong imports and reverse imports (European machines with software localized). .

Since Samsung set up a factory in Tianjin (including Shenzhen KJ), Samsung’s parallel imports have only been from Hong Kong banks (including Malaysian parallel imports) and the water supply has changed. At the same time, due to the Hong Kong banks (produced in Tianjin or KJ) The price is not as good as that of water-modified products, and the warranty is not as good as that of licensed products, so it slowly withdraws from the market. The Samsung parallel imports now basically refer to water-modified products. Of course, sometimes some parallel imports from Southeast Asia, such as parallel imports from Singapore and Malaysia, will also flow into the country. < /p>

The hardware of Samsung's licensed products and parallel products (modified products) are different, so the software versions cannot be mutually updated. But the functions are exactly the same. The only differences are price, appearance and warranty. Samsung licensed products can enjoy the warranty of Samsung KF, while all parallel products can only be covered by the seller's warranty. Since the quality of Samsung mobile phones has always been relatively high, the sales of Samsung parallel imports in China have always been relatively good. It is said that more than 80% of Samsung mobile phones in China are parallel imports.

Therefore, some parallel imports are produced domestically and some are produced abroad.

5. What are the characteristics of Hong Kong banks?

Hong Kong banks are a type of parallel imports.

Features are:

A. Cannot be guaranteed in mainland China;

B. The appearance is the same as licensed products;

C. They are produced in Tianjin or KJ, and some are made in South Korea;

D. The labels and instructions are in traditional Chinese;

E. The input method includes phonetic input and pinyin input.

F. The price is slightly cheaper than licensed products.

Hong Kong Bank is also called Bank B.

6. What is water diversion (B goods)?

This name was created by JS. Originally there was no such thing. JS uses various methods to make the water-modified labels, shells, etc. the same as licensed products. to obtain higher profits.

To a certain extent, water reform can be regarded as a water reform machine that renovates and replaces the shell, because no matter how the shell (or the label of the shell) is replaced, the original hardware has been changed. state.

7. What are the disadvantages of water diversion?

A. It is no longer an original parallel import, so any problems may arise in the future. A more common problem is: the label pretending to be anycall falls off as soon as it is touched. The external screen becomes gray. The machine is loose, etc.

B. Pretend to be licensed goods or Hong Kong banks to sell at high prices. In fact, the price of water conversion should be lower than that of pure water conversion, because it is no longer original.

C. When problems arise, disputes may easily arise.

8. What is water reform?

Water modification is a parallel import of European and American licensed products (without Chinese language, of course) after the software has been localized.

Because this kind of parallel import is produced abroad, the hardware quality is no less than that of licensed products. The initial Chinese version of the software may have some bugs, but after improvements, it will function exactly the same as the licensed version.

It is a real parallel import machine, used for Samsung mobile phones. These mobile phones were originally sold to Europe. Since the interface of the mobile phones was in English, it had to be changed to Simplified Chinese when sold in China. JS translated the English software into Chinese software (added Chinese character library) to make it a mobile phone that supports Chinese. Sales, but the Chinese font library will occupy part of the memory. Since the software of the mobile phone is relatively low, there will be some minor faults in the early stage, such as crashes, inability to connect to GPRS, inability to input Chinese, etc. However, with the upgrade of the software version, these problems will disappear. can be resolved. The hardware quality of the water modification machine itself is still trustworthy, so there is no need to worry.

9. What are the characteristics of water reform?

The water-modified casing does not have anycall, but has samsung. The labels on batteries and accessories for water modification are in foreign languages. The instructions are reprinted and the quality is rough. And it may not match the functions of the mobile phone!

Water reform generally does not have seat charging, only wire charging, because Europeans do not use seat charging. But js is usually paired with a garbage recharge, and this recharge is generally unusable.

10. What are the parallel import versions? How to check?

The commands to check the version on Samsung mobile phones are:

The software version to check is *#9999#, licensed version It’s *#1234#. Or *#8999#8378#

The hardware version is *#8888#, and the licensed version is *#1111#. Or *#8999#8378#

The last 2 characters are the version number.

11. Is Hong Kong Bank worth buying?

Not worth it. Reason: The price of the Hong Kong store is slightly lower than that of the licensed product, but there is no warranty from Samsung KF; at the same time, compared with the water-modified ones, the price is much higher.

Therefore, there is a general saying: water (reform) is not as good as water (reform), and Hong Kong (operation) is not as good as line.

12. What tricks might js do in parallel imports?

A. Use crooked goods to pass off as good goods. This is relatively easy to identify. As long as you eliminate the worship of parallel imports and know a little bit about parallel imports, you can identify it.

B. Using fake accessories as genuine ones. The more common ones are fake batteries.

13. Do parallel imports have data cables?

Some parallel import data cables are standard, such as s200. Some don't.

14. How big is the price difference between parallel imports and licensed products?

In the early days of listing, the price of parallel imports was equivalent to about 60% of the licensed price. In the future, as the price declines, the difference will generally be about 20-30%.

15. Why do the prices of parallel imports rise instead of falling during the holidays?

This is completely the law of the market. During the holidays, parallel imports are in short supply, so price increases are normal. The licensed ones generally have activities during festivals.

16. When is the better time to buy parallel imports?

Theoretically, parallel imports can be purchased at any time.

For novices and people who don’t know how to distinguish the authenticity of accessories, it is recommended to buy parallel imports when they first come on the market, because the quality of the accessories can be guaranteed at this time. But the price at this time is relatively high.

17. Why do some parallel imports appear to be made in China?

This is because Samsung’s line buffers are universal since n628. Some parallel imports are equipped with line flushing in China.

What do 18, 410, 410c, and 418 stand for?

For Samsung products, generally speaking, the last number is 8 for the Chinese version, and the last number is 0 for the European version, so 418 It is the code for Chinese licensed products, 410 is the European code, and 410C is the Southeast Asian (Malay) version.

The functions of the three are the same.

19. What are the proofs for purchasing parallel imports? ?

Generally speaking, the following documents are needed to purchase parallel imports:

A. A sales and shipping document stamped by the seller, which is equivalent to an invoice.

B. Warranty certificate, this is not a formal warranty card, it is just the parallel import seller’s commitment to parallel imports.

20. Is there any warranty for parallel imports?

Because parallel-imported mobile phones are also mobile phones, you can claim warranty.

Generally speaking, the warranty conditions for parallel imports must be agreed upon with the seller before purchase. The more common ones are 15 days for machine replacement and 1 year warranty (6 months for accessories). These terms should be written on the sales receipt or warranty certificate.

If you don’t ask for a warranty, the purchase price can be reduced.

21. Can parallel imports enjoy Samsung KF’s warranty?

Free warranty is not possible.

But as long as it is paid, Samsung KF can definitely provide services.

22. Can parallel-imported batteries be made in China?

Yes. The quality of batteries made in China such as Scud and Desai is comparable to the original ones.

There may be some differences in size, color, capacity, etc.

23. The difference between parallel imports and licensed Samsung mobile phones:

a. Front. Check whether the front of the phone is marked with the word Anycall. Some are licensed products, otherwise they are parallel imports. In the test prototype, the Anycall logo is designed at the bottom of the home screen, while the official version will be designed at the top of the screen.

b. Keyboard. Open the phone and check the stroke marks on the keyboard. If it is transparent, it is a licensed product, otherwise it is a parallel import.

c. Input method. If you need to change the input method to input Chinese characters, it is a parallel import. The details are as follows: Some parallel imports have no Chinese input in the default input method after turning on the computer, and you need to modify the input method before inputting.

d. Mark the nameplate. Take out the battery of the mobile phone and check the back of the mobile phone. If the nameplate is blurred, it is a parallel import.

Gently scratch the IMEI number barcode with your finger. If it can be easily blurred, it is a parallel import.

e. Circuit board. Take out the SIM card and check the circuit board under the insert. If you find that the phone model marked above is not the required phone model, it must be a parallel import. If the licensed product is SGH-E608, if it is marked as SGH-E600, it is parallel import.

f. Mobile phone battery. If the Chinese characters on the battery nameplate are unclear, fuzzy and small, it is a parallel import; if it is marked MADE IN JAPAN or FINISH IN KOREA, it is a parallel import. Among them, especially BD (Thin Electronics), many JS will make a fuss on BD.

g. Packaging box. If the printing is blurry and the text is in Traditional Chinese or all in English, or the paper quality is poor, it is a parallel import.

h. Data cable. If the data cable is roughly made and the color is dull, it is a parallel import. Through comparison, it can be clearly found that the connectors of licensed data cables are smaller than those of parallel imports.

i. Accessories. Check the mobile phone accessories. If you find any loopholes in the mobile phone accessories, you should report it in time to prevent being deceived by JS.

j. Supplied with CD. If you find that the phone model marked on the supplied CD is not the one you should use, you should be careful. The difference between parallel imports and licensed Samsung mobile phones:

k. Front. Check whether the front of the phone is marked with the word Anycall. Some are licensed products, otherwise they are parallel imports. In the test prototype, the Anycall logo is designed at the bottom of the home screen, while the official version will be designed at the top of the screen.

l. Keyboard. Open the phone and check the stroke marks on the keyboard. If it is transparent, it is a licensed product, otherwise it is a parallel import.

m. Input method. If you need to change the input method to input Chinese characters, it is a parallel import. The details are as follows: Some parallel imports have no Chinese input in the default input method after turning on the computer, and you need to modify the input method before inputting.

n. Mark the nameplate. Take out the battery of the mobile phone and check the back of the mobile phone. If the nameplate is blurred, it is a parallel import. Gently scratch the IMEI number barcode with your finger. If it can be easily blurred, it is a parallel import.

o. Circuit board. Take out the SIM card and check the circuit board under the insert. If you find that the phone model marked above is not the required phone model, it must be a parallel import. If the licensed product is SGH-E608, if it is marked as SGH-E600, it is parallel import.

p. Mobile phone battery. If the characters on the battery nameplate are not clear or fuzzy and small, it is a parallel import; if it is marked MADE IN JAPAN or FINISH IN KOREA, it is a parallel import. Among them, especially BD (Thin Electronics), many JS will make a fuss on BD.

q. Packing box. If the printing is blurry and the text is in Traditional Chinese or all in English, or the paper quality is poor, it is a parallel import.

r. Data cable. If the data cable is roughly made and the color is dull, it is a parallel import. Through comparison, it can be clearly found that the connectors of licensed data cables are smaller than those of parallel imports.

s. Accessories. Check the mobile phone accessories. If you find any loopholes in the mobile phone accessories, you should report it in time to prevent being deceived by JS.

t. Supplied with CD. If you find that the phone model marked on the supplied CD is not the one you should use, you should be careful.

Identification:

1. The button above the infrared ray in the upper right corner of the fuselage should be the "recording" function. If it is "push to talk", it is definitely not licensed in mainland China. .

2. There is a blue letter "i" on the "0" key of the keyboard. When GRPS is activated, long press the "0" key to log in directly to NOKIA's WAP website.

3. The nameplate inside the battery compartment on the back of the mobile phone should have the words "Nokia Capcom Communications Co., Ltd." and a line with the words "MADE BY NOKIA" written on it.

4. Batteries shipped in mainland China should be all black with a hexagonal honeycomb pattern and an anti-counterfeiting label. If it is silver and black, it should be from a Hong Kong bank or something else.

5. After turning on the computer, enter "*#0000#" in standby mode. The latest version number should be 03.22, and the software date is November 25, 2004.

6. To distinguish between parallel imports and licensed products, Nokia Xingfo all have the label of Nokia Energy Equipment (Shanghai) Co., Ltd.

7. Distinguish authenticity based on the production batch number. Nokia mobile phones produced starting from November 15th will have the "production batch number" marked on the original battery, which should be consistent with the warranty card in the mobile phone sales package.

8. Distinguish the true ones by the packaging hand. All Nokia original accessories are packaged in one-time seals using heat sealing technology. Starting from the end of this year, they will also be gradually printed with laser anti-counterfeiting marks. Non-original accessories usually have no packaging or only simple packaging.

9. Distinguish the authenticity based on the appearance. Take the color case as an example. The color of the Nokia original color case is uniform, the lines between the colors are clear, the edges are polished smooth, and it is anti-proof. The radiation net is fine, even and neatly placed. The Nokia logo on the fake color shell is easy to fade, the color is uneven and there is no obvious limit between colors, the edges are sharp, the radiation protection network is rough, the placement is not skewed, the vehicle protection network is rough, and the placement is skewed .

10. Distinguish authenticity based on quality. Take headphones as an example. The buttons of real headphones feel comfortable, the voice is clear, and it is not easy to disconnect. The printing on the microphone is clear, while the keyboard of fake headphones does not feel good. , the call is noisy, easy to disconnect, and the printing on the microphone is rough

11. Look at the @ symbol on the numeric key of keyboard 1. The licensed product should be in the upper right corner, while the parallel import should be in the middle.

12. How to identify refurbished machines?

a Check carefully to see if there are any marks on the screen, data cables, headphone jacks, speaker holes, and strap holes.

b Check carefully to see if there are any dials on the battery lock. Are there any marks on the rotating shafts of the upper and lower covers? Are there any indentations on the two bumps on the upper cover?

c Carefully check whether there are records in the WAP and voice functions and the call record information function

e The shell depends on comparison (compare the brightness, uniformity, hue, granularity... with the machine that proves to be good)

f Smell the smell, the new machine has sandalwood, which is different from General detergent and perfume smell. There should be no sticky wax or oil on the fuselage (if there is any, it has been beautified by JS)

g Carefully check the SIM card contact points and whether the battery contact points of the fuselage are worn. Marks (distinguish the rest of the contact points)

h Check whether the gaps at the seams of the shell are even and below 1MM, whether there are pry marks, and whether there are pick marks at the two sealing points under the screen inside the upper cover.

h p>

i Compare the elasticity of the buttons and the brightness of the internal and external displays with the new machine

j Carefully look at the fixing nails of the fuselage to see if they are rotated, painted or inked (you can use a magnifying glass). Is there any prying mark on the trademark?

13. How to identify parallel imported batteries?

a. The label uses secondary printing technology. When viewed from the side facing the light, the color of the barcode part is darker; there are traces similar to pencil scratches on the surface of the label; the handwriting on the label is clear and textured.

b. The battery shell is made of solid material and is not easily damaged. It is difficult to open the battery by ordinary means.

c. The appearance has a certain roughness, but it feels comfortable when touching; fine longitudinal scratches can be seen on the inner surface under the light.

d. The width of the battery electrode is suitable for that of the cell phone battery. The corresponding position below the battery electrode is marked with a "+"|"-" mark. The isolation material of the battery charging electrode is the same as the shell material, but not the same. , with a dividing line in the middle.

e. The dot of the charging sign switch should be orange-red, and the hand should feel tight when turning it.

f. The pressing part of the battery lock is flat and has metal clips for reinforcement at both ends; the manufacturer's logo on the battery is clearly outlined. There is also a mold number on the bottom of the battery.

G. When the battery is placed on the mobile phone, it is well integrated.

H. If you tap the middle of the battery with your hand, the sound will be full without any hollow feeling.

The most effective way to judge the authenticity of a battery is the standby time.

14. How to judge the charger of parallel imports?

The genuine direct charging of parallel imports is gray-white, and the plug is It is a flat two-pin plug. There are English letters on the end of the line near the mobile phone. The label is pure English and is on light blue aluminum plastic paper. There are six lines of English written on the aluminum plastic paper: the first line is: TRAVEL ADAPTER (travel charger) , the second line is MODEL (model): *********, the third line is INPUT (input voltage): 100-240VAC 50-60Hz 0.15A, the fourth line is: OUTPOT (output voltage): 0.5V==0.7A, the first line is S/N (serial number): **********, the third line is: MADE IN KOREA (Made in Korea). Looking at the craftsmanship of the interface, the workmanship is very detailed and regular. The screws are multi-angular, and there is a number in small letters on the fine needle that connects to the mobile phone. The contacts at the interface are bright and consistent in color. Furthermore, the thread feels very soft and not shiny. , with English text printed online. But the fake thread is very hard and shiny and may have Chinese pinyin!

In addition: there is a small circuit inside the terminal 1 that is really directly connected to the mobile phone.

Parallel-imported stand-alone chargers are not genuine~~The original licensed stand-alone charger should look like this:

a. When charging without plugging in the battery, the indicator light does not light up;

b. When plugged in for line charging, the charger will perform a self-test, and the indicator light will light up red-green-orange in sequence, and then turn to red for charging;

c. After charging to full capacity, The indicator light turns green and stops changing.

15. Enter *#06# when the phone is in standby mode. The screen will display the serial number of the phone. Click it a few times, then remove the battery and check the serial number on the back of the phone. Check the packaging. If the serial number on the box is consistent, it is basically genuine.

Enter *#92702689# when the phone is in standby mode to check the call time. If it shows 0, it means it is a new phone. (Exclusively for Nokia mobile phones)

16. Look at the mobile phone case. New mobile phones have manufacturers' films on "key parts" for key protection. For example, the inner screen, outer screen, camera lens, etc. of a new mobile phone, because these parts will leave fingerprints whenever they come into contact. In addition, dust and traces of use are unavoidable for refurbished mobile phones. The gaps between the upper and lower shells of the mobile phone, the gaps around the keyboard, and the charger slot are all places where dirt can easily hide. The hinge of a flip phone There will also be traces of use left everywhere, so you should also pay special attention to it.

17. Look at usage records. Take a look at the games, text messages, phone book, call records, self-made ringtones and other items in the mobile phone to see if there are any records of use. If so, it is highly suspected of being refurbished. In addition, if the phone automatically shuts down or freezes frequently, it can be said with certainty that there is a problem with the phone's motherboard or software.

18. Check the receiver and screen carefully to see if there are any dead pixels and buttons, and check to see if there are any mismatched keys or malfunctioning keys. Bluetooth and see if it can be turned on. Turn the speaker up to the maximum and you should not feel much vibration. To check the signal, with the card inserted, hold the left side of the phone with your fist to see if the signal jumps strongly. If it's awesome, don't buy it.

19. Look at the price. Before buying a mobile phone, it is best to check the price of the mobile phone in the local newspaper or website. If the price quoted by the merchant is "very cheap", you should be wary. Such cheap mobile phones are either refurbished phones, products from informal channels, or accessories. "A pound is short of a pound". It is recommended to purchase from a regular seller with a good reputation and a high level of service, so that your legitimate rights and interests can be protected when there is a problem with your mobile phone.
