SIM card

SIM card(Sim card,English: Subscriber Identity Module Card) IsGSM,W-CDMAEtc.Mobile phoneThe ID number used in is recorded to identify the subscriberPrepaid Card[1].. In addition,2.5rd generation mobile communication systemOne of the methods ofIS-95The IC card used in is called.なお、日本のIn addition, JapancdmaOneSo this method was not adopted.

3rd generation (3G) mobile phonesSIM card for has expanded functions,W-CDMA What to use for (UMTS)UIM cardOr USIM card,CDMA2000The one used for is called R-UIM card, but since it is basically compatible, it is often called SIM card without any distinction.

Vodafone The former logo of (Vodafone) is based on the shape of this SIM card.


The SIM card has an IMSI (International Mobile Subscriber Identity) Is given a unique number, andPhone NumberCommunication is possible by connecting. By inserting and removing the SIM card, you can transfer the phone number to another mobile phone, or switch between multiple phone numbers on one mobile phone terminal.

However, the SIM card is not supposed to be inserted and removed frequently, and in order to ensure that the power of the SIM card is turned off before inserting and removing it, many battery-replaceable phone terminals require the SIM to be removed. The structure is such that the card cannot be inserted or removed.Since there is no restriction to remove the battery in a terminal that cannot replace the battery, the correspondence differs depending on the terminal, such as rebooting by inserting and removing the SIM, and replacing the SIM in airplane mode.

SIM cards available in Japan are usuallyCarrier (telecommunications company)It is a loan from, and must be returned when canceling.[2]. However,pre-paidIn the case of a SIM card, the cancellation procedure is not required because it expires after a certain period of time from the last use and you cannot make or receive calls.The expiration date is often about half a year after the last use.ソフトバンクモバイルのSoftbank MobilePre-mobileIn the case of, if you do not recharge within 360 days after the balance expires, it will be treated as automatic cancellation.


Storage capacity is 64kPart-Time Jobdegree.実用化されている最大容量はThe maximum capacity that has been put into practical use is2005(HeiseiAs of 17), it was 128 Mbytes.2008Some manufacturers have a policy of increasing the capacity to 20 GB by (1).小容量のカードでは契約者のWith a small capacity card, the contractorpersonal information,Phone bookCan only store about 50, but with a large capacity cardcontentInformation etc. can also be saved.

Half-duplex serial communication is used between the SIM card and the mobile device.The basic transmission speed is 9,600 bits / second, and the transmission speed can be increased to 111,500 bits / second by negotiation.

UICC (Universal Integrated Circuit Card) is a smart card used for GSM and UMTS mobile devices. In the GSM network, UICC has a built-in SIM app, and in the UMTS network, it has a built-in USIM app. Various other applications can be built into UICC.

The high-speed UICC standard (IC USB), which has recently been standardized by ETSI-SCP, modifies the USB 2.0 physical layer standard to enable communication at normal speeds of 12 megabits / sec (ETSI TS 102.600).In this case, UICC's C4 and C8 pins are used, and the USB standards above the physical layer are compatible.

Initially, the physical shape of the SIM card was a large card, but as the times went by and the size of mobile phones and their parts became smaller, the SIM card was also changed to a smaller size, and by 2020 it will be full. There are four standards: size SIM, mini SIM, micro SIM, and nano SIM.There is also a standard called eSIM that does not require the insertion and removal of a physical card in order to further reduce the size of parts.

Full size SIM

The original SIM cardISO / IEC 7810 ID-1So-called standard external dimensionsCredit cardSize (width 85.6 mm x height 53.98 mm x thickness 0.76 mm)Contact type IC cardso,1991Appeared in, earlyCar phoneAnd used in large mobile phones.the firstForm factor Also called 1FF in the sense of (The first form factor).

It is compatible with this full-size SIM that various small SIM cards that appeared later are provided in the state of credit card size, and it is often used by separating only the IC chip part from it. It is a remnant of the era when sexuality was planned.

Mini SIM

Mini-SIM (mini-SIM) is also called Plug-in UICC, and the external dimensions of the card areISO / IEC 7810 ID-000Width 25 mm x height 15 mm x thickness 0.76 mm.1996Appeared in. Also known as 2FF (The second form factor).

Although it is a standard that appeared after the full-size SIM, terminals that use the full-size SIM as it is were already obsolete during the full-scale popularization period of mobile phones, so this mini SIM is called "Standard SIM". It is often called "normal SIM".

Micro SIM

Micro SIM (microSIM, micro-SIM) is a smaller standard than mini SIM (mini-SIM), and the size is width 15mm x height 12mm x thickness 0.76mm.European Telecommunications Standards Institute (ETSI) standardETSI TS 102 221 V9.0.0Was determined by. Also known as 3FF (The third form factor), Mini-UICC.2003Appeared in.

It is still used on some MVNO terminals

Nano SIM

Nano SIM (nanoSIM, nano-SIM) is a smaller standard than micro SIM, and its size is 12.3mm in width x 8.8mm in height x 0.67mm in thickness. ETSIETSI TS 102 221 V11.0.0Determined by the standard.2012Appeared in[3].. Also known as 4FF (The fourth form factor).

ア ッ プ ルIn 2012iPhone 5As of 2020, this nano SIM has become the mainstream in mobile phones of most manufacturers.


eSIM (Embedded-SIM) is a standard that has a function equivalent to a SIM card built into the terminal and allows the information written on the SIM card to be downloaded remotely.2016Appeared in.Since there is no need to physically hand over the card, there is an advantage that the mobile phone line can be started quickly, and since there is no need to insert or remove the card, there is no need to provide a card slot in the terminal, further miniaturization and Terminal design with a high degree of freedom is possible[4].

Usually in the terminal as a very small chipSurface mountThe electrical interface is the same as a conventional card-type SIM. Also called MFF2 in the sense of form factor for M2M (machine to machine) equipment.[5]. However,GSMA In RSP version 2, not only the chip shape but also the card type is defined, and there may be implementations that deviate from the original meaning of Embedded in the standard.[6][7].

As a remote download type SIM2014Toア ッ プ ルWas realized in advance as a unique service called Apple SIM[8]Early Apple SIMs had to insert a traditional SIM card into the device. The first device officially compatible with the eSIM standard appeared in 2016SamsungIt became Gear S2 of.After that, Apple also2017From around that time, Apple SIM became an embedded type,2018It also supports the eSIM standard from the released terminals[9].


For UICC (SIM card, etc.)NFCBy incorporating a (Near Field Communication) application and interfacing CLF and UICC (SIM card, etc.) in a mobile device (mobile phone terminal) with SWP or HCI.Contactless paymentFunctions can be added to UICC (SIM card, etc.).

3GPPIn Release 7, non-contact typePrepaid CardAn extension to UICC that supports features has been decided.This is a standardized interface between UICC (SIM card, etc.) and CLF (Contactless Front End), a contactless wireless chip that performs wireless communication with NFC.This interface is called SWP (Single Wire Protocol). The CLF is usually mounted on the printed circuit board of the mobile device, but at the same time, the CLF is connected to the antenna for NFC mounted in the mobile device to communicate with an external reader / writer.

SWP is defined by ETSI-SCP (ETSI TS 102.613) and carries out serial transmission between UICC and CLF. SWP provides the physical layer and data link layer (MAC layer and LLC layer) between UICC and CLF. SWP communicates with two wires, C6 pin and ground C1 pin of UICC, but by using high and low two values ​​of voltage and current respectively, all double communication is performed.That is, the CLF side uses the two values ​​of high and low voltage, and the UICC side uses the two values ​​of high and low current for communication.However, the current value from the UICC side is valid only when the voltage value from the CLF side is high.By this method, the same transmission speed can be achieved for both uplink and downlink. SWP achieves a maximum speed of about 2 Mbps[10]Has been reported.

HCI (Host Controller Interface), which manages communication between UICC and CLF in the upper layer of SWP, is also standardized by ETSI-SCP (ETSI TS 102.622). The main purpose of HCI is to communicate between UICC and CLF, but it has a star topology configuration with CLF as the master, and routing between nodes is supported.


ICCID (Integrated Circuit Card ID)
The maximum is 19 digits, the 1st and 2nd digits are industry identification (89 for telecommunications), the 3rd and 4th digits are country codes (81 for Japan), and in the case of Japan, the 5th and 6th digits are business numbers and 7 --The 18th digit is the card number, the 19th digit is the card numberCheck digitIs[11].

in Japan,2rd generation (2G) mobile phonesWas the representative of the 2G system that uses a SIM card during the mainstream period.GSMWas not used because it was not serviced.

However,NTT DoCoMo OfCar phoneSome models of the machine used an IC card called "DoCoMo application card", which is the same size as a credit card.In addition, some of NTT DoCoMo's embedded packet communication platforms (such as taxi credit card payment devices) use the "DoPa chip".This is unique to JapanPDC (MOVA) Method.

In addition,au(KDDI-Okinawa Cellular PhoneUnion) Also internationalroamingStrengthening (Global Passport GSM)CDMA 1X WINso,R-UIM card(au IC card) Has been introduced, and all Japanese 3G mobile phones will use IC cards equivalent to UIM cards.

In addition, with Japanese 3G mobile phones, IMSI and IMEI (International Mobile Equipment Identity, Phone's unique number) is often protected, and if a UIM card different from the one used for download is inserted, it may be possible to make calls and communications, but not use the downloaded content. .. The same possibility occurs when the UIM card is reissued due to loss, damage, malfunction, theft, etc.

As a usage other than SIM card calling and communication, there is a service called First Pass of NTT DoCoMo.利用者がThe userElectronic certificateIs issued and stored in the FOMA card,SSLClient authentication andElectronic signatureIt is used for.なお、このサービスはIn addition, this service is2012(24)May 8Ends with[13].
