| | 5 | ==== SIM Card Setting Intro ==== |
| | 6 | * '''International Mobile Subscriber Identity (IMSI)''': 15 digit unique identifying number that is used to identify the subscriber to the service. Typically issued by the operator. IMSI consists of: |
| | 7 | * MCC: Mobile Country Code - identifies geographic region of the SIM card |
| | 8 | * MNC: Mobile Network Code - identifies the operator |
| | 9 | * MSIN: Mobile Subscriber Identifier - identifies individual subscriber |
| | 10 | |
| | 11 | Typically [https://en.wikipedia.org/wiki/Mobile_country_code MCC and MNC] are 5, 6 or 7 digit combination leaving 10, 9 or 8 digits for the subscriber serial number. |
| | 12 | |
| | 13 | * '''Authentication Algorithm''': A number of [http://www.gsma.com/aboutus/leadership/committees-and-groups/working-groups/fraud-security-group/security-algorithms standard security algorithms] are sued in cellular networks. The two that are related to SIM configuration are: |
| | 14 | * XOR - Mostly used for testing |
| | 15 | * [http://www.sharetechnote.com/html/Handbook_LTE_Authentication.html Mileanage] - Mostly used in production. Parameters stored in SIm realated to authentication are: |
| | 16 | * '''Ki''': Subscriber Authentication Key (128 bit) |
| | 17 | * '''OP''': Operator Code - same for all SIMs from a single operator |
| | 18 | * '''OPc''': [http://diameter-protocol.blogspot.com/2013/06/usage-of-opopc-and-transport-key.html Derived operator code] unique for each SIM |
| | 19 | |
| | 20 | These keys [http://niviuk.free.fr/milenage.php should be validated] before deployment. |
| | 21 | |
| | 22 | * ''' Integrated Circuit Card Identifier (ICCID)''': [https://en.wikipedia.org/wiki/Subscriber_identity_module#ICCID up to 22-digit number uniquely identifying the SIM card]. Consist of: |
| | 23 | * Issuer identification number (IIN): Up to 7 digits with |
| | 24 | * Major Industry Identifier (2 digit): Hard-coded to "89" identifying ''telecommunication'' |
| | 25 | * Country code (1-3 digit): SIM Issuer Country Code |
| | 26 | * Issuer Identifier (1-4 digit): SIM Issuer (operator) Code |
| | 27 | Valid IINs are published in [http://www.itu.int/pub/T-SP-OB.1040-2013 the Annex of the ITU Operational Bulletin]. |
| | 28 | * Individual Account Identifier (variable length): |
| | 29 | * Checksum (1 digit) : One digit [https://en.wikipedia.org/wiki/Luhn_algorithm Luhn algorithm check code]. |
| | 30 | |
| | 31 | |
| | 32 | * '''Answer To Reset (ATR)''': Information message that helps reader access the card information (i.e. describes [https://www.eftlab.com.au/index.php/site-map/our-articles/169-demystifying-atr-answer-to-reset how to read the SIM card]). |
| | 33 | |
| | 34 | NOTE: International Mobile Equipment Identity (IMEI) is not related to SIM but is rather a unique identifier of the device. |
