Serial number is the most common method,It must also be done,The specific method is to enter the standby state"*",The number displayed on the screen and the comparison behind the fuselage are on the line,The consistent may be licensed。

2 There is a Chinese comparison on the keyboard of the mobile phone of the Hong Kong Bank, while the water-modified mobile phone is artificially carved on the comparison, rough and unnatural, opaque, and can be seen by turning on the keyboard light in a dark place, especially on the metal keyboard like Motorola V3.

3 Open the back cover of the mobile phone, remove the battery, there are mobile phone models on the back of the fuselage, many models of the Hong Kong bank are the same as the mainland, such as the Hong Kong model of Samsung D508 is also called D508, and the water model is D500 (probably because Chinese prefer the number "8").

4 Samsung's Hong Kong mobile phone has the same "angcall" logo on the panel as the licensed product, while the water reform only has the "samsung" logo.

5 Check the mobile phone version, licensed mobile phones have a relatively fixed official version, and parallel imports also have some specific versions, some versions will only appear on the mobile phone of the Hong Kong bank, the specific version of each mobile phone is different, and it can not be introduced one by one, which requires everyone to find some professional mobile phone forums to consult the relative mobile phone masters.

6 Some of the phones may only be water-modified phones and are not available in Hong Kong and other Chinese regions, including some smuggled from South Korea and Japan.

7 Pure English mobile phones are also water modification machines, if you do not need Chinese text messages, and you are fully confident in your foreign language level, you can also choose, because such mobile phones have not been flashed, and the quality is the same as licensed goods.

8 The ** of parallel mobile phones is also relatively fixed, and the Hong Kong line of the same mobile phone is almost the same across the country, if it is much cheaper, it is a water reform or refurbished machine.

9 Check the production date to distinguish the refurbished machine, such as Nokia's non-smartphone standby state can enter "* 92702689", you can display the production date and other information, if the date is too early, do not buy; The identification method of specific brands is not the same, you can find the search method on the Internet by yourself.

10 The refurbished machine will also have some traces of wear on the shell and fixing nut, in addition, the battery of the refurbished machine is generally assembled, one is because JS is reluctant to match the original battery, the other is that the contacts of the original battery have been worn out, it is easy to view, and the shell of the refurbished machine is likely not to be original. However, the situation of refurbished machines is not serious, so I will not repeat it.

Authentic licensed goods, some called line A, are all the same thing. This kind of mobile phone refers to the product through the manufacturer's formal channels, and is generally sold through the first system. Next to the battery slot at the back of the machine, there is a network access license from the Ministry of Information Industry.

Each mobile phone will come with a national guarantee certificate "three packs card", which clearly stipulates: if there is a non-human quality problem, it will be returned unconditionally within one week from the date of purchase, and it will be replaced unconditionally within fifteen days, and it will be guaranteed for one year free of charge. The authenticity of authentic licensed goods can be identified by three ways: **, text message, and Internet inquiry.

The ** of licensed mobile phones is more expensive.
