Today's netizen I want to tell you about the serial code of mobile phones, and also attached the "May Day" holiday purchase guide, which is very rich and practical!
Take it this time HTC For example, each mobile phone has its own IMEI code, which is equivalent to everyone's ID card and unique. However, if you are stolen by a malicious person, it may bring you losses or some disadvantages! The serial code of mobile phones is the same. It is easy for businesses to get a real serial code. For example, if there are two mobile phones in the store, there are two serial codes. Then all other refurbished phones can be changed to the same serial code as these two mobile phones. Why? It's very simple. These two serial codes have new dates, Refurbishment machines are generally recycled machines with a long date! After the modification, it was sold to different people. The person who bought it went to the official website to check. The date was still very recent. He thought it must be a brand new machine, but he did not know that other people were also using this serial code. The buyers don't know each other, so they can't know this!
Identification of origin, sales place and production date of HTC mobile phones: (Note that the following does not apply to mobile phones with serial codes modified by defective merchants!)
1. Identification of mobile phone serial code:
First, open the cell phone battery compartment, and you can see a string of codes such as S/N: HT22DV201764. We use SSYMDPPZZZZZ to refer to this string of codes. The first two SSs of S/N are the origin code: SZ Shenzhen; SH Shanghai; HT Hsinchu (Taiwan) CH Wuhan. At present, HTC mobile phones are mostly produced in Hsinchu, Taiwan, and Shanghai, China. But please note that this does not mean that there are no mobile phones from other places. The third Y of S/N is the production year: 0 is 2010, 1 is 2011, and the fourth M of S/N is the production month: the number 1 - the number 9 represents January September, the letter A represents October, the letter B represents November, the letter C represents December, and the fifth D of S/N is the production date: the number 1 - the number 9 represents No. 1 - No. 9, the letter A - the letter Z represents No. 10 - No. 31 (IOQU is not used in 26 letters). The sixth and seventh digits of S/N represent the factory product code. The product codes of different batches are different. The last five digits of S/N represent the factory product serial number. The serial numbers of products of the same model are different.
According to the above method, we can preliminarily identify the HT22DV201764 in the above example. The mobile phone is made in Hsinchu, Taiwan, and delivered on February 15, 2012. IMEI and S/N have an analogy relationship in the HTC official database according to the coding rules, and can be converted to each other: that is, IMEI can be obtained by querying S/N in the official database, and S/N can also be obtained by querying IMEI, which corresponds to each other one by one. Therefore, the S/N recognition accuracy is very high, and you can use it with confidence. The ex factory date of the mobile phone can be obtained through S/N. The closer the production date is to the purchase date, the less likely it is to be a refurbished mobile phone. For example, the machine in February 2011 was bought in March 2011, which is brand new. If it was bought in February 2012, it must be Refurbishment Oh, because no seller is so stupid that they can store the machine for one year before selling it. In one year's time, the price of the machine will drop by 100%! The only reason is that the machine has a problem, and it has been renovated by defective businesses and then resold. Therefore, by comparing the date of manufacture with the date of purchase, we can preliminarily judge whether the machine is brand new.

2. Mobile version<place of sale>:
Mobile version , refers to the original place of sale of the mobile phone and the country to which the mobile phone is sold. HTC mobile phones are sold all over the world, including Taiwan version, Hong Kong version, Asia Pacific version (including Singapore version, Malaysia version, Thailand version, Indonesia version, etc.), North American version, European version (German version, British version, etc.), mainland products (sold to mainland China), etc; And customized mobile phones produced by HTC for T-mobile, TimVodafone and other foreign operators and China Mobile, China Telecom, China Unicom and other domestic operators; There are also special mobile phones that HTC manufactures for Google.
Mobile phones of the same model and different versions<sales place>differ only in the built-in language. The reason is simple: there is no need to support simplified Chinese for mobile phones sold to Europe, because there must be fewer Chinese people in Europe than in any other city in China; Similarly, it is unnecessary for mobile phones sold to China to support Spanish. Therefore, the difference is only in the built-in language. It is the consistent practice of the manufacturer that only the local official language and local common language are built into the mobile phones in the original sales place. For phones of the same model and different phone versions<sales place>, the built-in languages are different, and the pre installed functions may be different. The reason is similar to the difference between the built-in language. HTC mobile phones sold to the Arab world will be pre installed with the Koran, and mobile phones sold to China will be pre installed Sina Weibo , Tencent QQ, HTC mobile phones sold to the United States and Europe need to be pre installed with Twitter and Facebook... All these are software that manufacturers can add or remove in order to adapt to the local consumer market, and software naturally will not affect the quality of products. The quality of mobile phones of the same model and different versions<sales place>is exactly the same. The reason is simple: there is no need to develop another mobile phone with different hardware standards or technical standards for a certain region.
As a special model, some customized phones may have different functions from the prototype phones. Customization opportunities can deeply customize the software functions and network functions expected by the operator, and the customized machine may be equipped with a network lock, which limits the use of the operator's SIM card only. If you need to use other operators' SIM cards, you generally need to unlock them, and you generally need to charge extra for unlocking.
Phone language: the language that can be displayed directly when the phone is delivered. The world is so big and there are so many languages. It is unnecessary for a mobile phone to support the languages of all countries. Therefore, it is the consistent practice of manufacturers to build in local official language and local common language. At present, it is known that the phones sold in Asia Pacific, Hong Kong, Taiwan and mainland China have built-in simplified Chinese, but please note that the so-called Hong Kong version and Taiwan version are better than the European version only as a means of promotion for some businesses, and there is no such statement at all. In fact, all versions of the same model of mobile phones<sales place>have the same quality. The mobile phone version<sales place>has no direct relationship with the quality of the mobile phone.

SHIP S-ON official factory status, security lock open status. The SHIP S-OFF security lock is closed, the security lock has been closed, the white card has been released, and the ENG S-OFF security lock is closed, the security lock has been closed, and the software has been released.
4. Official or third-party verification

Directly log in to the official website of HTC and click on the top of the page“ technical support ”, and then select "Mobile phone sales place inquiry" at the bottom of the page, and then enter the IMEI code or SN code (note that the two codes can be queried separately, and the two queries must correspond to the same demerit). The inquiry will show detailed information about the origin, sales place, production time, model, etc!

"51" purchase strategy:
After working for seven consecutive days, the May Day holiday finally came. Generally, holidays are the peak period of the consumer market, and many users will choose to buy mobile phone products during this period, because everyone thinks that there will be some promotional activities for consumer products during holidays, but the gray market is different from it.
First of all, the price of smuggled mobile phones is determined by the market supply and consumption. For example, if a mobile phone has more supplies and fewer buyers, it will be cheaper or cheaper. If there are fewer supplies and more buyers, it will be expensive or more expensive! The number of people who go shopping on May Day will increase greatly, so it is a matter of course that the price of parallel mobile phones will rise!
Secondly, in general large holidays, the gray market may also be on holiday. That is to say, when the source of gray goods is cut off, all sellers will stock up in advance, which means that the quantity of goods picked up before the holiday will increase significantly, and the price of wholesalers will also increase with the increase of the quantity of goods picked up. In addition, the risk of sellers preparing goods in advance, the shortage of goods, and the sales volume mentioned above will increase, Under such circumstances, we can't go without raising the price!
Thirdly, many people may see various promotional activities coming out, but some of them are actually higher prices, and then the whole promotion price, or give some worthless gifts, the so-called "wool comes from sheep", I think everyone knows! Some even use refurbished mobile phones to promote sales. The price is so cheap that it attracts people's attention, so this also constitutes an increase in the risk of buying parallel mobile phones on holidays!
Finally, Parallel mobile phones Because the profit is relatively low, it can't support any promotion activities at all. It's impossible to promote at a loss. Is there such a businessman? Of course, it should be noted that for parallel goods, there will be promotional activities for licensed goods, because licensed goods are supported by profits!
