The STK (SIM Toolkit) card is a SIM (Subscriber Identity Module) card for GSM networks. Aside from supporting all standard functions of a Phase2+ STK card, this product has a variety of exciting features and capabilities. These features and capabilities include support for all versions of the COMP-128 authentication algorithm on both GSM900/1800 networks, data security, speed enhancement, anti-cloning mechanisms.
Being feature-rich, the STK (SIM Toolkit) card can be used any GSM operator to deploy a host of applications and value-added services for their subscribers via the SIM card.
STK card complies with the following international standards and requirements:
GSM 11.11 version 8.3.0 (Release 1999)
GSM 11.12 version 4.3.1 (Release 1998)
GSM 11.14 version 8.3.0 (Release 1999)
GSM 03.48 version 8.5.0 (Release 1999)
STK card can be customized to meet our customer's requirements and also supports the following:
All GSM Phase 2+ STK card functions and RFM (Remote File Management). Also capable of a variety of IOD (Information On Demand) and common STK VAS (Value Added Services)
Special applications like Super Phonebook, Group SMS sending, Multi-IMSI, Enhanced ADN, Personalized STK Menu, Mobile-banking etc.
Authentication algorithms like COMP128-V1, V2, V3, V0 (see note) and XOR. Proprietary algorithms defined by the operator can also be provisioned into the card 's unique cardACS (see note) security technology, authentication counter, anti-cloning and cloning detection features.
These features cause extreme difficulty for hacking by cloning tools.
Various popular encryption algorithms and data integrity mechanisms like DES, 3DES, PBOC and MAC etc.
Widespread compatibility with various with handsets of different brands
Note: V0 is an authentication algorithm with enhanced security defined by China Mobile (CMCC).
CardACS: Our unique next-generation SIM card security technology.
CardDPS-II: Our unique second-generation data security technology. Intelligently prevents loss and damage of SIM data. This prevents loss of data and prolongs the usage lifespan of the SIM card
Note: Maximum user space refers to the remaining space left in the card after setting ADN, SMS, and essential GSM files.
SIM of size 16k uses the ADN/SMS configuration of 100/20 records.
SIM of size larger than 16K uses the ADN/SMS configuration of 200/40 records.
The figures above are generic data gathered under normal working conditions. The ADN/SMS numbers are for reference only.
STK card has been an ideal choice for GSM operators who wish to rollout SIM cards with STK services, multi-IMSI and value-added services.
Examples of mobile-data services deployed using the STK card include information on demand (IOD), mobile banking and location-based services under China Mobile's service brandsi.e. Monternet and M-Zone. Apart from being widely used by China Mobile and China Unicom, the STK card has been used by other GSM operators abroad.
The product is available in a variety of memory configurations. Our customers now have the flexibility of choosing different memory configurations for their different subscriber segments.
