< H2 > extended data:I. The 20 following the SIM of China Mobile is the digital description
for example: 8986 00 60 26 07 4 5622354
8986 represents the country, China
00 represents the operator, China Mobile
79 represents the third and fourth digit of the mobile phone number, In this way, 1360
26 represents the issuing province number
07 represents the issuing (business) year 2007
4 represents the manufacturer
5622354 represents the user identification number For example: 8986 01 07 00 029 530981 s
8986 represents the country, China
01 represents the operator, China Unicom
07 represents the year of card issuing (Manufacturing), 2007
05 represents the third and fourth digit of mobile phone number, so the card is 1300
029 represents the issuing region number
530981 represents the user identification number, Relatively random
s represents the manufacturer
The first to sixth digits are the operator code: the common China Mobile is 898600; China Unicom is 898601; China Telecom: 898603; The seventh is the service access number; The 8th bit is the function bit of SIM card, which is generally 0, and the 3rd bit is for prepaid SIM card
the 9th and 10th digits are the codes of card issuing provinces, that is, two digits are used to represent the corresponding information of card issuing provinces, for example, 01 represents Beijing, 02 represents Tianjin, 03 represents Hebei, 04 represents Shanxi, 05 represents Inner Mongolia, 06 represents Liaoning, etc
the 11th and 12th digits: year number, that is, the last two digits of the SIM card business year; 13th digit: the code of the supplier, that is, the code of the SIM card manufacturer; The 14th to 19th digits are the user identification code; The 20th bit is the check bit
extended data:
SIM card has data storage function, which can store telephone number and other information; When using SIM at the same time, the mobile phone actually sends commands to the SIM card, which should be executed or rejected according to the standard specifications
the number composed of 20 digits on the back of the SIM card is the electronic serial number of the SIM card, also known as the IMSI number, which is unique in the world and assigned to each operator by ITU. When the service is opened, the telephone number and the IMSI number are bound on the switch, so that the SIM card can be used
At present, there are three sizes of mobile phone SIM cards:
-
at present, SIM cards are divided into standard size SIM cards, that is, large cards
-
followed by the emergence of micro SIM cards, commonly known as small cards
-
the last nano SIM card is the micro SIM card currently used in Apple's iPhone 5 series
in other words, the reason for the emergence of these three SIM cards is thanks to apple. Apple released the iPhone 4 and iPad in 2011, and used the micro SIM card for the first time. Because the iPhone 4 pursues a thinner body, compresses the internal space of the body, and increases the battery capacity, the volume of the micro SIM card is twice that of the standard SIM card

1-6 digits: international mobile operator identification number (IMSI)
898600 (China Mobile), 898601 (China Unicom)
after that, the definition of China Mobile and China Unicom are different<
China Mobile:
the 7th and 8th digits correspond to the 3rd and 4th digits of the network number
(that is, the two digits after the first 13 of the mobile phone number,
for example, 70, then the mobile card number is 1370xxx)
the 9th and 10th digits
provincial numbers: 01 Beijing, 02 Tianjin, 03 Hebei, 04 Shanxi, 05 Inner Mongolia,

30 Xinjiang, 31 Tibet
the 11th and 12th digits: the year when iccid was compiled
number 13: the number of the SIM card manufacturer< At present, there are nearly ten manufacturers of SIM cards in China, such as Gemplus in France, Schlumberger in France, orga in Germany and Ig chip manufacturers in China
in order to distinguish different procts,
different manufacturers put codes such as 1, 2, 3 and 4 on this bit to show the difference
for example: "1" means that this card is a proct of Baojia company in France
digit 14-19: user identification number
for example: 89860 07031 01120 94320
is the global communication number starting with 1370 of Tibet mobile, which was proced in 2001
digit 20: check number<
China Unicom:
the 7th and 8th digits: the year when iccid was compiled
digits 9-19 are not the same as the definitions of several versions of Unicom cards
(some digits 10-12 are the local area code, and 0 is added before less than 3 digits,
for example, Chongqing is "023", some digits 11-13 are the local area code),
the number of the SIM card manufacturer is in front of the area code, and the user identification number is behind the area code
digit 20: check number
for example, 89860 10110 23117 0983s is the number of Chongqing Unicom proced in 2001
in addition to the standard 20 digit number, there are still some mobile phones
issued by provinces and cities with only 14 or 12 digits printed on SIM cards
this is mainly e to the omission of the top six international call receiving codes and network numbers of China Mobile
