How to distinguish licensed goods from water
What about "parallel imports"? Parallel imports are not fakes. There are still many netizens who don't know what a parallel mobile phone is. By default, parallel mobile phones refer to mobile phones that enter the mainland market from abroad, Hong Kong, Macao and Taiwan without normal customs channels. Parallel imports also have a name, originating in Europe. The so-called parallel mobile phones (originated in Europe) are actually mobile phones that should have been sold to other countries or regions and entered the domestic market after evading tariffs. Simply put, parallel mobile phones are mobile phones that have not declared tax through normal channels. Therefore, the quality of parallel mobile phones and licensed mobile phones is the same, and there is no difference in hardware. The original products produced by the original factory are only different in sales area and software, and some models are even better than domestic licensed mobile phones because of different sales countries. Coupled with the huge difference in sales prices, many people like to choose parallel (original European version) mobile phones.
Parallel mobile phones circulating in the market can be roughly divided into four categories:
The first category is line B (licensed goods in parallel imports), which is smuggled into the mainland. The quality of B-line mobile phones is the same as that of licensed products. It is also registered in the telecom network, but it is not registered in the official customer service. Generally, it is a small quantity of goods from manufacturers. Compared with banks, the difference is after-sales service. The B-line mobile phone warranty is the place where you bought it. Go to the point of sale for repair.
The second category is the Bank of Hong Kong, which, as the name implies, is the licensed mobile phone in Hong Kong. For some reasons, many mobile phones in Hong Kong are cheaper than those in the Mainland. Some unscrupulous profiteers saw this and sold some Hong Kong mobile phones to the mainland through special channels, but there was no warranty in the mainland, and Hong Kong banks were also classified as parallel imports.
The third category is English revision machines, which are authentic parallel imports (water reform machines). These machines were originally sold to Europe, America and other countries and smuggled into the mainland. By upgrading the mobile phone software, they support simplified Chinese. Due to tariffs, the price of revised mobile phones is often much lower than that of mainstream mobile phones.
The fourth category is refurbished machines. This kind of mobile phone is second in tax evasion, and the key is that the quality is not guaranteed, which is the most lethal to buyers.
The first type of B-line in the mainland has a small amount of circulation in the market, so parallel import industries are usually divided into three grades: A-goods, B-goods and C-goods. A goods refer to licensed goods smuggled from Hong Kong, without warranty and after-sales service; B goods are "parallel imports" that smuggle mobile phones sold to Europe and the United States to domestic sales; C-goods mobile phones are usually called "refurbished machines" and "assemblers". Note: goods B are not line B, so don't confuse them.
The subtle difference between goods A (usually called Hong Kong bank) and goods B (usually called European version) lies in the keyboard. There are no Chinese strokes printed on the keyboard of the European version machine, and the strokes are all added later. However, at present, domestic parallel mobile phones have almost formed an industrial chain, and the technology of adding strokes on the basis of the original keyboard is very mature, and there is almost no difference. As for the European version of the software, behind-the-scenes inventory dealers spared no expense to obtain the Chinese fonts of the Asia-Pacific version of Samsung mobile phones through various channels, and organized a cracking team to analyze the software and write it into parallel mobile phones; Later, based on the accumulated experience and software technology, the cracking team developed many different versions by itself, and the related development tools became more and more mature, so that some domestic models that have not yet been listed can be landed first; From many bugs in the initial version to the current perfection, parallel imports have been continuously upgraded with the release of new machines, and gradually cultivated into a force that can compete with licensed products today. That is to say, before it is sold to mainland consumers, it has been set to the same Chinese version as mainland licensed products, and there will be no localization problem.
At present, many parallel mobile phone stores offer one-year or half-year free warranty. If a mobile phone shop says that paying more is the only guarantee, then don't go there to buy it. It's a lie.
The mobile phone market is booming day by day, and major businesses are vigorously promoting sales, using some promotional means to attract buyers. There is also a big price war, and the price can't come down. In fact, it is also a mixed bag. Many merchants cheat users with parallel mobile phones or upgraded versions. Therefore, when you need to buy a mobile phone, you must carefully identify it. Netease lends you a pair of discerning eyes, so that you can no longer "see flowers in the fog".
Parallel mobile phone identification steps:
First, check whether there is a "network access permit" sign posted by the Ministry of Information Industry;
Then check the configuration of the mobile phone, including whether the battery and charger are from the original factory.
Use, generally affixed with the manufacturer's laser anti-counterfeiting logo;
Finally, confirm whether the dealer's warranty is consistent with the manufacturer's warranty.
In addition, experts also suggest that you should pay attention to the following three issues when buying a mobile phone:
Electronic serial numbers are inconsistent.
Every mobile phone has a unified electronic serial number. When the mobile phone products leave the factory, the electronic serial number will be input into the database. When the warranty is needed, the data will be retrieved to determine whether to sell to the China market. If a mobile phone is found to be out of the China market, it will not be guaranteed. Therefore, once the parallel mobile phone fails, it is very difficult to maintain and complain. Users can check the IMEI code of the mobile phone when purchasing it. Press * # 06 # on the mobile phone first, and the number 15 will be displayed on the mobile phone, which is the IMEI code of this mobile phone. Then open the cell phone battery cover. There is a sticker in the mobile phone with an IMEI code on it, which should be exactly the same as the IMEI code displayed on the mobile phone. Then check the sticker on the outer box of the mobile phone. There should also be an IMEI code on it, which should be exactly the same as the IMEI code displayed on the mobile phone. If these three codes are inconsistent, it means there is something wrong with this mobile phone.
Sales refit machine
Due to the great price difference between Chinese mobile phones and English mobile phones, such as Ericsson GF768E and GF768C, many unscrupulous merchants privately convert English mobile phones into Chinese mobile phones, which harms consumers to reap huge profits. For example, the popular model cd928+ is very popular in the market because it can input Chinese through various Chinese character input methods with complete functions. The functions of cd928 and d938 are almost the same as those of cd928+, but the software version is different, so it is impossible to input Chinese. So some merchants changed the software of cd928 and cd938 to one that can input Chinese, and then described this mobile phone as a cd. But this violates Motorola's regulations. Motorola China will not guarantee this kind of mobile phone. Moreover, some people report that the mobile phone with upgraded software will be garbled and crashed during use. What's more, the shell of counterfeit brand-name mobile phones was bought back in the coastal parallel market and replaced with the old motherboard for sale as a new machine.
Stealing batteries and chargers
Nowadays, the profit of mobile phones purchased through formal channels is relatively thin, so unscrupulous merchants have made an abacus on the configuration of mobile phones. For example, when the manufacturer leaves the factory, there is only one battery and one travel charger in the mobile phone package. These must be made by the original factory. Of course, this price is also the line price, and the profit of the merchants is not too high. If the telecommunications sector engages in preferential activities and implements unified preferential prices, the profits of merchants will be thinner. As a result, the merchant added a battery and a charger to the mobile phone factory configuration, and of course the price was relatively high. But most users have little experience in buying mobile phones, so when buying a mobile phone, it is definitely not enough to think of a battery, so they bought a mobile phone with two batteries and two chargers. As we all know, the profits of businesses are often reflected in the increased configuration-batteries and chargers are not original goods.
It is difficult to distinguish the true and false battery from the appearance, but the voltage of the false battery is very unstable, which causes considerable damage to the machine and often leads to disconnection during the call. In coastal areas, this kind of fake mobile phone battery is surprisingly cheap, such as 30 yuan, but it takes 400 ~ 600 yuan to enter the mainland. Who dares to use this battery?
The original chargers of some high-end mobile phones have many functions, such as automatic voltage selection and automatic protection after the battery is fully charged. The price is generally above 600 ~ 700 yuan, while the counterfeit charger only costs 300 ~ 400 yuan.
How to identify parallel mobile phones
[a method]
First, check whether there is a "network access permit" sign posted by the Ministry of Information Industry; Finally, confirm whether the dealer's warranty is consistent with the manufacturer's warranty.
Electronic serial numbers are inconsistent.

What's more, the shell of counterfeit brand-name mobile phones was bought back in the coastal parallel market and replaced with the old motherboard for sale as a new machine.
[Method 2]
Parallel mobile phones cannot enjoy the warranty and maintenance provided by the original factory or in line with the original technical standards. Authentic mobile phones can enjoy one-year warranty and other after-sales services that meet the technical standards of the original factory. Even if the seller closes down, the original factory can bear the responsibility for product quality.
Generally speaking, the sellers of parallel mobile phones cannot provide consumers with services such as warranty that meet the original technical standards. Needless to say, the mobile phone detector alone costs more than 400 thousand. Parallel sellers may promise to give you a warranty, but their so-called warranty is often just that they have repaired it for you. The biggest worry is that the seller is here today and may close down tomorrow. What should you do if there was something wrong with your mobile phone at that time? Because it is parallel imports, the original factory has no legal obligation to provide after-sales service, so the original factory generally refuses to provide after-sales service such as warranty for parallel mobile phones.
The sale and use of parallel mobile phones are prohibited by the state.
1995 No.79 1 Article 5 of the Notice of the Ministry of Posts and Telecommunications on Issuing the Provisions for Examination and Approval of Telecommunication Terminal Equipment Entering the Network stipulates; All telecommunications terminal equipment connected to national communication must conform to the technical system, standards and communication industry standards stipulated by the state and the relevant business regulations of the Ministry of Posts and Telecommunications, and have the network access license issued by the Ministry of Posts and Telecommunications; Telecom terminal equipment that has not obtained network access license shall not be connected to the national communication network for use. Article 17 stipulates that without the approval of the Ministry of Posts and Telecommunications and the permission to enter the network, production and distribution units shall not publicize or sell telecommunication terminal equipment.
The batteries configured by parallel mobile phones are mostly fake batteries.
Many consumers who come to consult are equipped with fake batteries, but because consumers generally don't indicate the batteries in the invoices when buying mobile phones, they often find that they have been cheated after using them for a period of time and can't get justice. According to incomplete statistics, more than 40% of consumers who come to our company for consultation take fake batteries from sellers.
Parallel mobile phones are affixed with forged and counterfeit network access licenses, and the relevant national laws and regulations explicitly prohibit sales, so parallel mobile phones are counterfeit and shoddy goods.
Anti-counterfeiting common sense battery charger anti-counterfeiting
The most common fraud method: replace the original battery or charger and sell it at a simple or complete price, or sell it with other brands of batteries at the original price.
Precautionary measures: pay attention to whether the battery and charger are fully equipped and whether there are manufacturer's signs and anti-counterfeiting trademarks.
Selling fake batteries and chargers with mobile phones
Fake battery: usually four or five camera batteries are connected together and attached to the battery case of the mobile phone.
Fake charger: generally, the old or repaired charger is repackaged and sold.
Preventive measures:
A, pay attention to whether there is a manufacturer's anti-counterfeiting mark.
B, choose a reliable retailer to buy.
C, the original battery has many anti-counterfeiting details.
What are licensed and parallel imports?
Domestic licensed goods
Domestic licensed products refer to products approved by manufacturers and licensed by the Ministry of Information Industry of China, which are directly sold by merchants or manufacturers' branches in designated areas. Because licensed products need to make agents and their branches get reasonable or even profiteering profits, and they must pay tariffs and taxes that meet the requirements of the local government, the price of licensed products is often higher. However, because there are regular agents in the local area, the warranty and after-sales service of products are often more secure.
Domestic license warranty:
Warranty service is provided by the manufacturer's specialty stores and customer service centers.
Parallel import (European original)
"Parallel imports" is believed to be a sensitive word in the eyes of netizens. What is parallel imports? Parallel imports are not fakes. There are still many netizens who don't know what a parallel mobile phone is. By default, parallel mobile phones refer to mobile phones that enter the mainland market from abroad, Hong Kong, Macao and Taiwan without normal customs channels. Parallel imports also have a name, originating in Europe. The so-called parallel mobile phones (originated in Europe) are actually mobile phones that should have been sold to other countries or regions and entered the domestic market after evading tariffs. Simply put, parallel mobile phones are mobile phones that have not declared tax through normal channels. Therefore, the quality of parallel mobile phones and licensed mobile phones is the same, and there is no difference in hardware. The original products produced by the original factory are only different in sales area and software, and some models are even better than domestic licensed mobile phones because of different sales countries. Coupled with the huge difference in sales prices, many people like to choose parallel (original European version) mobile phones.
Are parallel imports (original European version) in English or Chinese?
Parallel (original European version) mobile phone software will be upgraded to simplified Chinese version, which is the same as domestic licensed products. Unless there are special circumstances in technology or software, such as n-gage;
Warranty for parallel imports (original European version):
What about the warranty? In fact, both parallel imports and licensed products have a one-year warranty, but parallel imports have a warranty abroad. Of course, no one will take them abroad for maintenance. Therefore, parallel merchants all said that there is no warranty, and parallel imports do not guarantee when they go out;
Hong kong licensed goods
Many friends are familiar with the concept of "Hong Kong licensed goods". Hong Kong licensed mobile phones are sold in the Hong Kong market, and these products have formal sales methods and channels in Hong Kong. Hong Kong licensed products are authentic compared with domestic licensed products. Because it is manufactured by the original factory, you don't have to worry about the hardware at all. The operation and function are the same as those of domestic licensed products. However, due to the tariff differences between the Mainland and Hong Kong, and the pricing of manufacturers in the Mainland and Hong Kong are also different. Even the mobile phones officially sold in Hongkong are quite different from those of the same model in Chinese mainland. However, some mobile phone manufacturers have in one way or another transferred products that should be sold in Hong Kong to the mainland for sale and smuggled them directly back to Guangzhou from Hong Kong. Therefore, licensed mobile phones in Hong Kong have the labels of specialty stores and Hong Kong mobile operators on the back.
Do Hong Kong licensed products have simplified Chinese?
Generally speaking, licensed mobile phones in Hong Kong are traditional mobile phones and simplified Chinese, which is the same as domestic licensed mobile phones (except that some models of manufacturers do not have simplified Chinese). If the menu is in English or other languages, the relative price will be cheaper.
Hong Kong License Warranty:
At present, there are two kinds, one is a Hong Kong bank that can guarantee the whole country and needs to provide Hong Kong tickets; One is that Hong Kong guarantees for one year. Although Hong Kong is not far from Guangzhou, it really needs to be repaired. Running back and forth is not only troublesome, but also takes a lot of time. Some merchants simply said that they did not guarantee the licensed products in Hong Kong.
Lianbao licensed goods
Joint warranty licensed goods is a special kind, which is only the view of the industry; In the early days, it was licensed in Hong Kong, that is, the "B" line. Early customer service also provided a warranty for this kind of mobile phone, and later all the warranties were cancelled. Also, there will be fake "network access license" labels and laser anti-counterfeiting labels on the fuselage of these "licensed products", but the major customer service will not be responsible for the warranty, but the dealers will be responsible for the warranty. This kind of mobile phone is exactly the same as genuine licensed products in both appearance and packaging, and it also has the "Three Guarantees" brand. Some merchants will sell it in the market as genuine licensed products, so you must carefully check whether the mobile phone is "guaranteed licensed" when you buy it. Don't buy "joint warranty licensed goods" at the price of genuine licensed goods. At present, only Philips mobile phones have joint warranty licensed products on the market!
Guarantee the warranty of licensed goods:
Warranty licensed goods can only be guaranteed at the designated customer service office or directly by the dealer.
B gua
The quality of B-line mobile phones and licensed mobile phones is the same, the difference is after-sales service. The mobile phone warranty of line B is based on where you bought it, so you can only go to the point of sale for repair. Quality is the same as licensed goods, but the difference is after-sales service. At present, only LG mobile phones have line B on the market.
B-line warranty:
For line B, the warranty service is provided by the manufacturer's customer service center.

It is generally believed that smuggled goods that do not pay customs duties are parallel imports. Actually this definition is not accurate. Parallel imports refer to products that should not be sold in a certain country or region, but sold in that country or region, or directly sold by unauthorized regular dealers. He has nothing to do with the place of origin, but only with the place of sale. Licensed products refer to products with warranty sold in Chinese mainland. Parallel imports are products that can enjoy warranty abroad. If our licensed products are taken abroad, they are also parallel imports! There are several ways to modify the cloned mobile phone: one is the parallel import we mentioned earlier; There is also cross-selling, such as stringing mobile phones sold in place A to place B. In another case, the old mobile phone recovered from the second-hand mobile phone market is revised, and the shell with good color is polished and repaired, and then the serial code (that is, IMEI code) is written. There are also cases where recycled water dispensers and old mobile phones are written as shells and then sold as new mobile phones.
Then it is necessary to confirm whether the dealer's commitment is consistent with the manufacturer's warranty. To buy a mobile phone, you must ask the merchant to write clearly the brand, model, IMEI code, network card number and serial number of the mobile phone on the invoice and warranty card.

1. How to identify refurbished machines?
1. Look carefully at the screen for traces, data cable, earphone hole, speaker hole and tape hanging hole for dust.
2. Look carefully at the battery lock of the fuselage for any poke marks, the rotating shafts of the upper and lower covers for any rotation marks, and the two bumps of the upper cover for any indentation.
3. Carefully check whether there are records in WAP, voice function and call record information function.
4. Carefully check whether the contact point between the SIM card and the battery of the fuselage has wear marks (distinguish other contact points).
5. Check whether the gap at the joint of the shell is even, whether it is below 1MM, whether there are pry marks, and whether there are pry marks at the two sealing points under the screen in the upper cover.
6. Look carefully at whether the fixed pins of the fuselage are rotary printing, painting and inking (you can use a magnifying glass), and whether there are pry marks on the trademark.

3. Identification of commonly used mobile phone batteries
This is the basic identification method of most brands, and the identification methods will be different when encountering new factory batches of batteries.
1. Nokia battery
Method 1: the real battery is not rough when touching the front with fingers, while the fake battery is obviously sandy when scraping with nails; Plastic nails at both ends of real batteries are easy to shell, while fake batteries are hard.
Method 2: The seams of the upper and lower covers of the real battery are tight, and the seams of the fake battery are relatively large, especially at the four corners.
2. Motorola battery
Method 1: The printing quality of fake batteries is much worse, the character edges are rough, and the bar code is often broken. The electrodes of the real battery are in close contact with the shell, and all four electrodes are on the same plane, which is very neat.
Method 2: The existing batteries are marked in red on the randomly sold batteries: "Random batteries such as retail can't enjoy the three guarantees from the manufacturer", so as to prevent merchants from replacing random batteries with fake batteries.
3. Sony Ericsson battery
Method 1: Real batteries are made of high-quality engineering plastics, but this is only the difference before. Now the fake battery has been matte, but the matte particles in the shell of the fake battery are much thicker and appear dim, and the weight of the fake battery is less than that of a really thin battery.
Method 2: Look at the electrode. In a well-lit place, there are small squares with dark lines on the electrodes of real batteries, while the electrodes of fake batteries have not been treated.
Method 3: Precautions In the illustration, the illustration with the children's logo in the lower left corner is clearly printed by the original electricity, and the children's eyes, mouth and fingers can be clearly seen, but the group electricity is basically a few small black dots and fingers.
Method 4: label of origin. The label of the original place of origin is very clear. The position of many handwriting is related to the effect of the version. The lines of these letters are not clear.
Method 5: There are three copper contacts at the top of the back of the battery and on the right side, and the relatively symmetrical side has a raised part with a thickness of about 0. 1MM, which is completely integrated with the plastic of the shell.
4. Samsung battery
Method 1: The plastic of the real battery is frosted, but it feels smooth. Although the fake battery is also frosted, it feels rough.
Method 2: Label: The edges of real battery characters are smooth, and the precautions for red printing are bright. The fake battery has rough edges, dim red and broken characters.
Method 3: Barcode: The barcode of the real battery has a concave-convex feeling, but the fake battery does not.
There is no WIFI module in licensed products, and this is the most obvious in parallel products.
