Explanation:

Imsi (short for International Mobile Subscriber Identity)

Imsi has a total of 15 digits, and its structure is as follows:

MCC + MNC + min

MCC: Mobile country code, mobile country code, 3 digits in total, 460 for China;

MNC: Mobile networkcode, mobile network code, two digits in total

In China, the mobile code is e 00 and 02, China Unicom code is 01, and China Telecom code is 03

In combination, this is (also the code in the APN configuration file of the Android phone ):

China Mobile: 46000 46002

China Unicom 46001

China Telecom 46003

For example, a typical imsi number is 460030912121001.

IMEI is short for International Mobile Equipment Identity (international mobile device identification)

IMEI is an electronic serial number consisting of 15 digits. It corresponds to each mobile phone one by one and is the only one in the world.

It consists:

1. The first 6 digits (TAC) are "model approval numbers", which generally represent models

2. The next two digits (FAC) are the "last Assembly number", which generally represents the origin

3. the next 6 digits (SNR) are "serial numbers", which generally represent the production sequence numbers.

4. the last 1-digit (SP) is usually "0", which is the Verification Code and is currently in use.
