00:00:01,666 --> 00:00:04,966

In this video, we mainly explain how to check the sales regions

2

00:00:04,966 --> 00:00:06,533

and models of iPhone

3

00:00:08,866 --> 00:00:10,833

Introduction of sales regions

4

00:00:12,600 --> 00:00:16,933

Sales region refers to the different versions of iPhones sold in different countries,

5

00:00:17,033 --> 00:00:18,766

and their names are also different.

6

00:00:23,000 --> 00:00:27,100

For example, the iPhone sold in the United States is called the US version,

7

00:00:27,633 --> 00:00:30,766

the iPhone sold in Hong Kong is called the Hong Kong version,

8

00:00:31,666 --> 00:00:34,933

and the iPhone sold in China is called the National version

9

00:00:35,533 --> 00:00:38,466

Different versions of iPhones in different sales regions,

10

00:00:39,533 --> 00:00:42,466

they will vary in terms of network and applications

11

00:00:43,633 --> 00:00:46,333

For example, the Japanese version of the iPhone

12

00:00:46,333 --> 00:00:48,733

cannot turn off the sound when taking pictures

13

00:00:49,400 --> 00:00:52,666

Some iPhones of the Japanese version or the US version

14

00:00:52,833 --> 00:00:56,100

when they're brought to China, the calling function cannot be used

15

00:00:58,266 --> 00:01:00,966

Understanding this basic knowledge will be a great help

16

00:01:00,966 --> 00:01:04,033

to our second-hand iPhone sales or maintenance in the future

17

00:01:06,100 --> 00:01:07,600

View of sales region

18

00:01:08,666 --> 00:01:10,933

Click the Settings icon on the desktop,

19

00:01:13,866 --> 00:01:15,266

click the General icon,

20

00:01:18,666 --> 00:01:20,200

click the About icon,

21

00:01:22,966 --> 00:01:25,366

and then check the model number on the interface

22

00:01:27,466 --> 00:01:33,000

We see that the model number of this iPhone is MWNE2CH/A

23

00:01:35,166 --> 00:01:38,566

Check the letters before the slash at the end of the model number,

24

00:01:39,933 --> 00:01:42,233

different letters represent different regions

25

00:01:44,000 --> 00:01:47,733

The English letter in front of the slash of this model is CH

26

00:01:48,200 --> 00:01:50,466

According to the sales area swap table,

27

00:01:51,400 --> 00:01:54,300

we found that CH represents the National version

28

00:01:56,200 --> 00:02:00,566

If the slash is preceded by a letter J, it means the Japanese version

29

00:02:01,400 --> 00:02:04,166

Most of the Japanese versions have network locks,

30

00:02:04,900 --> 00:02:07,366

we can't use them after inserting the phone card

31

00:02:07,700 --> 00:02:10,400

If LL is displayed in front of the slash,

32

00:02:10,700 --> 00:02:14,800

it represents the US version, and ZP represents the Hong Kong version

33

00:02:15,166 --> 00:02:17,433

Next, let's demonstrate it on the iPhone

34

00:02:19,000 --> 00:02:21,033

We click Settings on the desktop,

35

00:02:21,566 --> 00:02:23,966

find General, click About

36

00:02:25,366 --> 00:02:27,866

We check the model number in About interface,

37

00:02:28,400 --> 00:02:33,300

the model number of this iPhone is MT472LL/A,

38

00:02:33,700 --> 00:02:36,733

LL means that the iPhone is the US version
