Types of cards
ICC UICC
SIM-- Single IMSI USIM
Dual IMSI CSIM
RUIM-- “Single”--CDMA
“Combo”--CDMA+GSM
SIM
 Subscriber Identity Module
 SIM-- Single IMSI
Dual IMSI (Multiple Subscription, Useful for Business needs)
 Polarization Mark, Chipset Mark (ID)
 SIM card was made in 1991 by Giesecke & Devrien (Munich) to Finnish wireless
network operator Radiolinja
Size: 32K,64K and 128K.
ICCID
 Integrated circuit card identifier (ICC-ID)
 Each SIM is internationally identified by its ICC-ID.
 ICC-IDs are stored in the SIM cards and are also engraved or printed on the SIM
card body during a process called personalization.
 The ICC-ID is defined by the ITU-T recommendation E.118.
 A 19 digits long including a single check digit calculated using
the Luhn algorithm.
 The format of the ICCID is: MMCC IINN NNNN NNNN NN C x
 MM = Constant (ISO 7812 Major Industry Identifier, = 89 for "Telecommunications
administrations and private operating agencies")
 CC = Country Code (i.e. 61 = Australia, 86 = China)
 II = Issuer Identifier (AAPT = 14, EZI-PhoneCard = 88, Hutchison = 06, Optus =
02/12/21/23, Telstra = 01, Telstra Business = 00/61/62, Vodafone = 03)
 N{12} = Account ID ("SIM number")
 C = Checksum calculated from the other 19 digits using the Luhn algorithm.
 x = An extra 20th digit is returned by the 'AT!ICCID?' command, but doesn't seem
to be an official part of the ICCID.
 For example, this ICCID = 8991101200003204510 provides the following
details:
 The first two digits (89 in the example) refers to the Telecom Id.
 The next two digits (91 in the example) refers to the country code (91-India).
 The next two digits (10 in the example) refers to the network code.
 The next four digits (1200 in the example) refers to the month and year of
manufacturing.
 The next two digits (00 in the example) refers to the switch configuration code.
 The next six digits (320451 in the example) refers to the SIM number.
7
ICCID
IMSI
 International Mobile Subscriber Identity
 Unique Value across all the operators through out the globe
 15- digit number
 Indicates the Home Network of the Subscriber
 All the Subscription details will be saved in the HLR against IMSI
 MCC: Mobile Country Code
 MNC: Mobile Network code
 MSIN: Mobile subscription identification number
Memory Architecture
 Flexible Architecture
 Similar to all the types of cards
 ‘3F': Master File;
 ‘7F': 1st level Dedicated File;
 '5F': 2nd level Dedicated File;
 '2F': Elementary File under the Master File;
 6F': Elementary File under a 1st level Dedicated File;
 '4F': Elementary File under 2nd level Dedicated File.
Permanent Vs Dynamic SIM Card Data
Permanent Dynamic
 SIM card type
 IC card identification - serial number
of card
 SIM service table - list of services
subscribed to
 IMSI
 CHV1( PIN1) and CHV2 (PIN2)
 PUK - Pin unblocking key
 Authentication key
 Location Information
 TMSI, LAI, LA update timer (t3212),
 Ciphering key and sequence number
 BCCH information
 List of carrier frequencies for cell
selection during handover and call
setup
 List of blocked PLMNs (FPLMNs)
 HPLMN search timer
RUIM
Removable User Identity Module
Non OMH OMH
1. Operator specific card 1. Can be used with any CDMA
2. Browser and DUN settings compatible targets
has to be written on to target (NV mode) 2. Multiple profiles: Browse, MMS, DUN and
LBS etc.
3. Simple PRL 3. PRL: Concatenated PRL
4. Prioritized Profiles
4. Combo: CDMA+GSM 5. Combo: CDMA+GSM
NV Vs RUIM
NV RUIM
 Non Volatile
 PRL (SID,NID) will be saved on the
target
ESN of the Handset will be sent to
the Network
 Browser and DUN settings on to
target
 Removable User Identity Module
 PRL (SID,NID) will be saved on the
card
 ESN of the card will be sent to the
Network
 Browser and DUN settings on to card
(OMH only)
PRL
 Legacy– 1X only
 Hybrid– Concatenated
USIM Vs SIM
USIM SIM
 UMTS-SIM
 Universal Subscriber Identity Module
 Global Phone Book & Hidden Phone
Book (Bank account no's)
 APN settings can be written directly
on to the card
 MMS can be stored on to the card
 Extended Phone book (256K)
 Backward compatible with 2G-GSM
technology
 Operator Logo can be stored on the
card
 More secured: Milenage and kausami
Algo’s
 GSM-SIM
 Subscriber Identity Module
 Global Phone Book
 NA
 NA
 Limited Phone book (32K or 64K)
compatible with 3G also
 Can’t store Images

UICC

UICC Vs ICC
UICC ICC
 Universal ICC
 Can have multiple Applications of
Similar Kind
 Can have 2 USIMs/SIMs
 A single card: USIM+ISIM+CSIM+SIM etc
 Used for 2G, 3G and 3G+ techs

 Integrated Circuit Card

 Single Application (USIM or IM
 SIM or RUIM or USIM
 Used for 2G and 3G only
CSIM Vs RUIM
CSIM RUIM
 3G, 3G+ Application
 runs on UICC
 2G and 3G
 runs on ICC and UICC
STK and DSTK
1) STK: SIM Tool Kit
for various value added services(VAS)
2) DSTK: Dynamic SIM Tool Kit
•Dynamic SIM menu of value added services
•operators have the flexibility to manage the list of services in SIM menu depending on
the subscriber's preferences
DSTK menu benefits:
•Browsing (the ability to retain subscribers in service by friendly and intuitive menu
navigation)
•The ability to update sections and adding new services in both a dynamic and a
resident parts of the menu
•Low requirements to the subscriber's handsets
