1. Regular mobile phones have the "Network Access Permit" mark of the Ministry of Information Industry on the back, but parallel-imported mobile phones do not.

2. When users purchase a mobile phone, they can check the IMEI code of the mobile phone. First, press *#06# on the mobile phone. Generally, 15 numbers will be displayed on the mobile phone. This is the IMEI code of the mobile phone. Then open the battery cover of the phone. There is a sticker inside the phone with an IMEI code on it. This code should be exactly the same as the IMEI code displayed on the phone. Then check the sticker on the outer box of the phone. There should also be an IMEI code on it, and this code should be exactly the same as the IMEI code displayed on the phone. If these three codes are inconsistent, there is something wrong with the phone.

Enter *#06#. If it starts with 0, it proves that it is genuine. If it does not start with 0, it is fake.

Enter *#06# and see what the 7th and 8th digits are. How many? 10 represents production in Finland, 40 represents Beijing, and 80 represents Dongguan

3. Check whether the string code on the packaging box matches the one on the back of the mobile phone. There is also the manual of the mobile phone. If it is not in Chinese, it is definitely not. Licensed. The last one is to press and hold the # key. Licensed mobile phones will ask you whether to switch numbers. Parallel imported mobile phones do not.

4. In appearance, regular mobile phones are more refined and have smooth keyboards; while most parallel imported mobile phones have a smooth appearance. It's rough, the color is muddy, and the keyboard also has signs of wear.

See if the price difference is too outrageous. If it is too far from the market conditions, you should suspect whether it is parallel imports.

How to identify a refurbished machine:

a Look carefully for marks on the screen, data cables, headphone jacks, speaker holes, and strap holes for dust

b Carefully check whether there are scratches on the battery lock of the fuselage, whether there are spin marks on the rotating shafts of the upper and lower covers, and whether there are indentations on the two bumps on the upper cover.

c Carefully check the WAP and voice functions and Whether there is a record in the call record information function

e shell depends on comparison (compare brightness, uniformity, tone, granularity... with a machine that is proven to be good)

f Smell the smell, the new machine smells like sandalwood, which is different from the smell of ordinary detergents and perfumes. There should be no sticky wax or oil on the body (if any, it has been beautified by JS)

g Check the SIM carefully Check whether there are any wear marks on the card contact points and the battery contact points on the fuselage (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 any pry marks inside the upper cover. Are there any scratches on the two sealing points under the screen?

How to identify parallel imports:

a. The label uses secondary printing technology, with the sides facing Looking at the light, the color of the barcode part is darker; there are traces on the surface of the label similar to pencil scratches; 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 determine the authenticity of a battery is the standby time.
