How to verify the authenticity of a mobile phone?

The mobile phone market is chaotic, so consumers need to distinguish carefully when buying, especially beware of buying refurbished machines, counterfeit machines, brand-name machines and parallel imports. In fact, there is a simple way to judge whether your mobile phone is faulty, and that is to check the network access license of your mobile phone.

Authentic licensed mobile phones should be affixed with a network access license issued by the Ministry of Information Industry. According to the information provided by Guangdong Communications Administration, there are four main ways to query the authenticity of network access license:

(1) manual telephone inquiry

Tel: 0 10-82058767, 820503 13.

Service hours: 8: 00 am-165438+0: 30 am and 1:00-5:00 pm from Monday to Friday (excluding holidays).

(2) Fax inquiry

Tel: 010-82056281; Fax: 0 10-82055685.

Service hours: 8: 00 am-165438+0: 30 am and 1:00-5:00 pm from Monday to Friday (excluding holidays).

(3) Website query

The website of "Telecom Equipment Access/Certification" of the Ministry of Information Industry was officially opened on April 2002 10. The website has "logo verification" column and "certificate query" column, and you can also query the pictures of mobile phones. Users can query the network access license information of all telecommunication equipment (including the approval of network access trial) from the website, verify the authenticity of network access permission marks (including network access trial marks), especially mobile phones, and provide the authentication function of one-to-one correspondence between network access marks and mobile phone body numbers (IMEI and ESN numbers), which is the only authoritative and reliable authentication method for mobile phones at present.

Tip:

When buying a mobile phone, you should first check the IMEI code of the mobile phone. The steps are as follows: Press the *#06# key on the mobile phone, and the general mobile phone will display 15 digits, 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, 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, press the above website or SMS to inquire.

Because there is a huge price difference between parallel imports, fake mobile phones and genuine licensed mobile phones, the sales of these mobile phones can bring huge profits, and unscrupulous businesses do not hesitate to take risks. Driven by high profits, parallel imports, old mobile phones and fakes are all sold as licensed mobile phones.

Here, Huatian communication mobile phone experts exclusively provide you with several magic weapons to distinguish between licensed goods, parallel goods and fake goods, so that everyone can distinguish between true and false with a pair of eyes and avoid the deception of unscrupulous merchants.

Trap 1: cheap parallel planes, no three packs.

There are two kinds of parallel imports, one is Hong Kong bank, also called Shuihang, which refers to mobile phones sold in China and Hongkong (Macau). The other is the European version of the water reform machine, also known as the European version, water reform and so on. , originally sold in Europe, smuggled to China.

Experts provide magic weapons:

(1) Seaplanes cannot enjoy three guarantees.

Each licensed mobile phone will be accompanied by a national warranty certificate "Three Guarantees Card", which can enjoy the three guarantees service in the after-sales service center designated by manufacturers nationwide. Parallel imports are not within the scope of 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 problem of parallel cargo aircraft parts is serious.

Most parallel imports are smuggled in through different channels. Battery, charger, earphone and other accessories are assembled in the mainland and then put into the packaging box. There is no guarantee that they are equipped with original accessories. According to the manufacturer's after-sales service regulations, it is difficult to enjoy the national warranty.

At the same time, because the power supply parameters of batteries and chargers suitable for Europe are different from those common in Chinese mainland, they must be modified and refitted to adapt to China, which is different from the machines originally sold to China.

(3) The software and functions of the tanker are incomplete.

The software parameters of parallel planes need to be reset before they can be used in China, and some software functions cannot be used in China because network operators do not provide them. For example, Sony Ericsson's Hong Kong mobile phone has no GPRS settings. Of course, there are other aspects here that are not exhaustive.

Generally, the English version of the European version is rewritten into the Chinese version, and the Chinese font takes up a part of the memory for other purposes, so the original functions of the mobile phone may be "sacrificed", and some small bugs may appear in the software of the mobile phone at first, such as crashing, unable to access GPRS, unable to input Chinese and so on.

(4) The keyboard and package of the water tanker are exposed.

There are no Chinese strokes on the keys of the European version of the machine, and the instructions and packaging are in English.

Differences between brands:

1, identifying Nokia's licensed products.

(1) You can check the version number, factory date and model code by entering *#0000#.

(2) You can enter *#92702689# to query the factory date of the motherboard.

2. Distinguish the licensed products of Sony Ericsson

(1) Press right * Zuo Zuo * left * in the standby screen to view the version information and test the function. In the version information, the models with C suffix are licensed products (such as K700c), if those with I suffix are Hong Kong banks, a few with A suffix are European versions, and the latter two are parallel imports.

(2) Seaplanes can't receive GPRS in Chinese mainland, so they must be reset.

3. Identify Samsung's authorized products

(1) Keyboard: Turn on the phone and check the strokes 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 you find that the mobile phone model marked above is not the required mobile phone model, it must be parallel. If the licensed product is SGH-E608, if it is marked as SGH-E600, it is parallel. Licensed goods generally end with 8, and parallel goods end with 0.

(3) Battery: If the battery nameplate is marked as made in Japan and painted in Korea, it is a parallel product. Especially thin electricity, many profiteers will make a fuss about thin electricity.

(4) Packing box: if the text is in traditional Chinese or English, it is parallel.

(5) Attached CD: If you find that the CD should not use the mobile phone model, you should carefully distinguish it.

4. Identify the licensed products of Motorola.

(1) Origin and production date query:

On the back of Motorola's mobile phone, there is a MSN mechanical serial number with *** 10 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, remove the back cover and battery, including:

Mc3-41e1/c 836 DD 3 p 4 r 350904805489928, where "c836dd3p4r" is MSN code with ten digits.

The meaning of representative is as follows: 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 place): 6- Tianjin, 3- Hangzhou, 2- USA, R- Germany, G- USA, 5- Hangzhou Eastcom, W- Singapore.

Year of production (fifth place): X- 1997, Y- 1998, Z- 1999, H-2000, B-200 1, C-2002, D-2003.

Production month (sixth place): A-B-65438+ October, C-D- February, E-F- March, G-H- April, J-K- May, L-M- June, N-P- July.

(2) Software and functions

Parallel planes don't have mobile QQ, so they can't check the version on the plane. The port water machine only has traditional Chinese characters to input. If you don't brush the Chinese package, the European version machine is a pure foreign language machine, and there are no strokes on the keyboard.

At present, Nokia N668 1, N3230, N6030, N3 108, N610, N6060, N70, etc. Sony Ericsson W550c, W800c, Z520c, K750c, K7000.

Trap 2: replace the old with the new and pretend to be licensed.

There are two kinds of machines that trade in old ones. One is a refurbished machine, that is, the second mobile phone is replaced with a new case and then packaged. Both parallel imports and licensed products can be refurbished and mainly sold to foreign markets. The other is a charger, 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 are licensed, and there is a warranty. Most chargers are sold locally.

Experts provide magic weapons:

(1) Most of the packages and accessories are counterfeit.

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 font of the instructions is not as beautiful as that of the original factory.

(2) You can't enjoy the three guarantees service.

You can't enjoy a one-year original factory warranty.

For example, Nokia and Sony Ericsson, which are easy to ship, have more refurbished machines, such as Nokia N83 10, N6 100, N3 100, N3 120, N76 10, N6260 and N6600.

The prices of refurbished machines, chargers and licensed products are very different, so be careful to be deceived when purchasing machines!

Trap 3: The mobile phone has been modified.

Reviser is equivalent to a makeover, such as T6 18 to T628, N82 10 to N8250.

Experts provide magic weapons:

The revision machine is mainly like main board structure, which uses other models to modify the software, passing low-end mobile phones off as high-end mobile phones, and earning a huge price difference. The performance of this kind of mobile phone is very unstable, and the accessories are also very difficult. Another trick, be careful to fall into the trap!

Trap 4: assemble the mobile phone, the source is unknown.

The trigger is called the assembling machine and the parallel installation machine. The trigger is a fake, which has a big quality problem and a big safety hazard!

Experts provide magic weapons:

Basically, some cottage factories or workshops manually weld components on inferior circuit boards of unknown origin, add accessories and assemble them into finished machines. Motherboard, electronic components, accessories, etc. None of them are original products, and there is no strict quality control or even cutting corners in the production process (for example, N76 10, N66 10, N6 100, etc. Do not install infrared rays, etc. ).

Generally speaking, the board machines are mainly produced for machines with good sales (e.g. 72 10/0,7250, 66 10/0,6100, T6 18, T628, etc.). ).
