The mobile phone market is confusing, so consumers need to distinguish carefully when buying, especially to guard against buying refurbished machines, counterfeit machines, miscellaneous brands and parallel planes. In fact, there is a simple way to judge whether your mobile phone is a faulty one, and that is to query network access license of the mobile phone.
Authentic licensed mobile phones should be affixed with the network access license issued by the Ministry of Information Industry. According to the information provided by Guangdong Provincial Communications Administration, there are four main methods to inquire about the authenticity of network access license:
(1) Manual telephone inquiry
Tel: 1-8258767 and 825313.
service hours: Monday to Friday (excluding holidays) from 8: am to 11: 3 am and from 1: pm to 5: pm.
(2) Fax enquiry
Tel: 1-8256281; Fax: 1-8255685.
service hours: Monday to Friday (excluding holidays) from 8: am to 11: 3 am and from 1: pm to 5: pm.
(3) website inquiry
The website of "Telecom Equipment Access/Certification" of the Ministry of Information Industry was officially opened on April 1th, 22. The website has a "logo verification" column and a "certificate inquiry" column, and you can also inquire about the pictures of the mobile phone. Users can query the information of all telecom equipment network access license (including the approval of network access trial) and verify the authenticity of the network access permission mark (including the network access trial mark) from the website, especially for mobile phones, which also provides the authentication function of one-to-one correspondence between the network access mark and the mobile phone body number (IMEI and ESN number), which is the only authoritative and reliable authentication method for mobile phones at present.

(4) SMS inquiry
1. Inquire about the information of network access license (including the trial approval for network access): send "RW# license number" to 95;
2. Inquire about the authenticity of the network access license logo (including the trial logo of network access): send "RW# license number # scrambling code" to 95;
3. if you need to check the authenticity of the mobile phone, send "RW# license number # scrambling code # serial number of mobile phone body" to 95, and wait for a reply.
Description:
* The license number is line 1 on the network access sign, and the scrambling code is line 3 on the network access sign;
* When you enter the serial number of the mobile phone body, you only need to enter the number, and you don't need to enter "/"or "-";
* if you need help information, just enter "RW".
Tip:
When buying a mobile phone, you should first check the IMEI code of the mobile phone. The steps are as follows: press *#6# on the mobile phone, and 15 digits will be displayed on the mobile phone, which is the IMEI code of this mobile phone. Then open the battery cover of the mobile phone. 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, which should also have an IMEI code, which should be exactly the same as the IMEI code displayed on the mobile phone. If the three codes don't match, there is something wrong with this mobile phone.
finally, make an inquiry by the above website or SMS.
because of the huge price difference between parallel imports, fake mobile phones and genuine licensed mobile phones, the sale of these mobile phones can bring huge profits, and unscrupulous merchants do not hesitate to take risks. Driven by high profits, parallel imports, used mobile phones and fake mobile phones are sold as licensed mobile phones.
Here, Huatian Communication mobile phone experts exclusively provide you with several magic weapons to distinguish licensed products from parallel products and fake products, so that everyone can distinguish the true from the false with a pair of eyes, thus avoiding the deception of illegal businesses.
Trap 1: Cheap parallel planes are not guaranteed by three guarantees
There are two kinds of parallel imports, one is Hong Kong banks, also known as water banks, which refer to mobile phones sold in Hong Kong (Macau) of China. The other is the European version of the water reform machine, also known as the European version, water reform, etc., which was originally sold in Europe and smuggled into China.
experts provide a magic weapon:
(1) Seaplanes can't enjoy the three-guarantee service
Every licensed mobile phone comes with a national warranty certificate "three-guarantee card", which can enjoy the three-guarantee service in the after-sales service center designated by the manufacturer. Parallel imports are not within the scope of the three guarantees, so you can't enjoy the right to change or return the machine. In this case, you can only contact and negotiate with the seller.
(2) The quality of the accessories of the parallel cargo plane is serious
Most of the parallel imports are smuggled in through different channels. The accessories such as batteries, chargers and earphones are all assembled in the mainland and then put into the packaging box. It is impossible to guarantee that the original accessories are equipped, and it is difficult to enjoy the nationwide warranty according to the after-sales service regulations of the manufacturers.
At the same time, because the power supply parameters of batteries and chargers suitable for Europe are different from those used in mainland China, they must be revised and modified to adapt to China, which is different from the machines originally sold to China.
(3) The software and functions of the water tanker are incomplete
The software parameters of the water tanker need to be reset before it can be used in China, and some software functions cannot be used in China because they are not provided by network operators. For example, Sony Ericsson's Hong Kong mobile phone does not have GPRS settings. Of course, there are other aspects that are not exhaustive here.
Generally, the English version of the European version is rewritten into the Chinese version, and the Chinese font occupies a part of the memory used for other purposes, so the mobile phone may "sacrifice" some of its original functions, and the software of the mobile phone may have some minor bugs at first, such as crashing, not being able to access GPRS and not being able to input Chinese.
(4) The keyboard and packaging of the cargo plane show clues
The keys of the European version of the machine have no Chinese strokes, and the instructions and packaging are in English.
differences among brands:
1. Distinguish Nokia's licensed products
(1) You can check the version number, production date and model code by entering *##.
(2) you can enter *#9272689# to check the date of manufacture of the motherboard and other information.
2. Identify the licensed products of Sony Ericsson
(1) Press right * Zuo Zuo * left * on the standby screen to view version information and test functions. In the version information, the models with the suffix C are licensed (such as K7c), if the ones with the suffix I are Hong Kong banks, and a small number of them have the suffix A as the European version, and the latter two are parallel imports.
(2) Seaplanes can't get GPRS in Chinese mainland, so they have to be set up again.
3. Identify Samsung's licensed products
(1) Keyboard: Turn on the phone and check the stroke marks on the keyboard. If it is transparent, it is licensed, otherwise it is parallel.
(2) Circuit board: Take out the SIM card and check the circuit board under the plug-in. If it is found that the mobile phone model marked above is not the required mobile phone model, it must be a parallel product. If the licensed product is SGH-E68, if it is marked as SGH-E6, it is a parallel product. Licensed goods usually end with 8, and parallel goods end with .
(3) battery: if the battery nameplate is marked as MADE INJAPAN and FINISH IN KOREA, it is a parallel product. Especially thin electricity, many profiteers will make a fuss about thin electricity.
(4) packing box: if the characters are in traditional Chinese or all in English, they are parallel imports.
(5) Attached CD: If you find that the CD is not the one who should use the mobile phone model, you should carefully distinguish it.
4. Distinguishing Motorola's licensed products
(1) Inquiry on origin and production date:
There is a MSN mechanical serial number on the back of Motorola's mobile phone, with 1 digits. It stands for "model code, manufacturer code, production year, production month, and product series number."
how to check the mechanical serial number of MSN code: turn off the machine, and remove the back cover and battery. Under the bar code on the back of the fuselage, there is a series of numbers: MC3-41E11C836DD3P4R359485489928, in which "C836DD3P4R" is the MSN code with ten digits.
stands for the following: the first three digits are model code, the fourth digit is manufacturer code, the fifth digit is production year code, the sixth digit is production month code, and the last four digits are serial number.
manufacturer code (fourth digit): 6- Tianjin, 3- Hangzhou, 2- USA, R- Germany, G- USA, 5- Hangzhou Eastcom, W- Singapore.
year of production (fifth digit): X-1997, Y-1998, Z-1999, H-2, B-21, C-22, D-23, E-24 and F-25.
production month (sixth digit): A-B-January, C-D-February, E-F-March, G-H-April, J-K-May, L-M-June, N-P-July, Q. The port water machine only has traditional Chinese characters to input. European version of the machine, if you don't brush the Chinese package, it is a pure foreign language machine, and the keyboard is printed without strokes
At present, Nokia N6681, N323, N63, N318, N611, N66, N7, etc., Sony Ericsson W55c, W8c, Z52c, K7c, K77, etc.
trap 2: replace the old ones with new ones, pretending to be licensed ones
There are two kinds of machines that replace the old ones with new ones. One is a refurbished machine, that is, the second mobile phone is replaced with a new shell and then packaged. Both parallel and licensed products can be refurbished and mainly sold to foreign markets. The other is the charging machine, mainly because the mobile phone has not been used for a long time, and the shell is relatively new, so it is difficult to see that it has been used. Some of them are licensed and have a warranty, and the charging machine is mostly sold locally.
experts provide magic weapons:
(1) Most of the packaging and accessories are imitations
Nowadays, people who do mobile phone renovation are more professional, and generally use highly simulated shells and accessories. Most of the packaging boxes are fake, the production process is rough, and the printing effect of the paper and fonts of the instructions is not as beautiful as that of the original factory.
(2) You can't enjoy the three-guarantee service
You can't enjoy the one-year original factory warranty.
for example, Nokia and Sony Ericsson, which are easy to ship, have more refurbished machines, such as Nokia N831, N61, N31, N312, N761, N623, N626, N66 and Sony Ericsson K7.
There is a big price difference between refurbished machines, charging machines and licensed machines, so be careful when buying machines!
trap 3: mobile phone makeover
The revision machine is equivalent to makeover, for example, T618 changes to T628, and N821 changes to N825.
Experts provide a magic weapon:
The revision machine is mainly the same as main board structure, and the software is modified by other models, and the low-end mobile phones are passed off as middle-end and high-end mobile phones, from which a huge price difference is earned. The performance of this kind of mobile phone is very unstable, and the accessories are also very tricky. Another trick, be careful to fall into the trap!
trap 4: assemble the mobile phone, the source is unknown
trigger, which is called assembly machine and installed in parallel. The trigger is a fake, which has great quality problems and security risks!
Experts provide magic weapon:
Basically, it is some small cottage factories or workshops, which manually weld components on inferior circuit boards with unknown routes, add accessories and assemble them into finished machines. Motherboards, electronic components and accessories are not original products, and there is no strict quality control or even cutting corners in the production process (for example, N761, N661 and N61 are not equipped with infrared rays, etc.).
in general, the board machines are mainly produced for machines with good sales volume (such as 721, 725, 661, 61, T618, T628, etc.).
