Blank GSM SIM Card , PVC/ABS/PET CARDS
HIGH QUALITY GSM BLANK SIM CARD FACTORY IN CHINA

1. Main Characteristics of SIM card
- Matching the standards of GSM11.11,GSM11.12,GSM11.14,GSM11.17.
- Matching the standard of ISO7816.
- Modularization design that is convenient to realize new functions .
- Optimized file management system, which supports file access path selection.
- STK data encrypt and checkout match the GSM03.48 standard absolutely.
- Supporting the norm of the China Mobile OTA2,the little assistant of no agony, Mass Storage Telephone Book,Group Sending Short Message etc.
- Supporting inner backup mechanism to insure the data Integrality.
- supporting T=0 transmission protocol,Communication velocity supports 372/1 and 512/8.
- Having the function that against inserting and pulling out of card when power on,and abnormal power off.
- Supporting the algorithm of DES ,3DES ,COMP128-1 and have protection against attacking mechanism.
- Supporting the function of the circuitry encrypt and circuitry secrecy ,preventing communication data against being stolen or juggled unlawful .And it can be used to check out the data integrality.
- Agile individuation instructions not only insure the require of safety management but also can satisfy all kinds of Customer’s requires of pluralistic STK functions.
- Perfect safety function and safety strategy,passed EAL4+safe authentication.

3. Communication Protocol
The Grcard SIM card products support the asynchronous half duplex character transmission protocol (T=0) that be defined in ISO7816-3 which use Direct convention.
It support the two kinds of parameters, F =512, D=8 and F=372, D=1 in this operate system communication.
4.Answer To Reset
For the T=0 communication protocol, the following forms is our SIM Card product’s default reposition response in formations:

5. Cryptographic System and Access Control
Card Holder Verification information(CHV),CHV unlock key,ADM key ,A3/A8 algorithm key Ki.
The following are the key type and id which be Grcard SIM card series products supported:

The file access policy for GSM application isdivided into 16 class , that are as follows:

The file access policy for GSM application is independent each other, For example:providing correct CHV2(CHV2 access condition satisfied) not means the operation controlled by CHV1 could be implement successfully.
6. Chip Parameters
Grcard telecom IC card chip prouduts are high performance IC used in smartcard. In the chip there are 8 bit micro processor,48K byte program memorizer(MASK ROM),256 byte internal RAM (SRAM),1K byte outside RAM(SRAM),32K byte data memorizer (EEPROM).
