Our SIM cards are blank can be programmable, the printing and programming can be customized if customer can provide card design and input data file.
The Blank SIM cards canot be use on equipments directly, need program the cards with real parameters, We can provide the card reader and free software to help you program the cards.
Standard,Algorithm,Certification 1-Support Milenage and XOR algorithm, Matching the standards of GSM11.11, GSM11.12, GSM11.14, GSM11.17. 2- Matching the standard of ISO7816. 3- Modularization design that is convenient to realize new functions . 4- Optimized file management system, which supports file access path selection. 5- STK data encrypt and checkout match the GSM03.48 standard absolutely. 6- Supporting the norm of the China Mobile OTA2,the little assistant of no agony, Mass Storage Telephone Book,Group Sending Short Message etc. 7- Supporting inner backup mechanism to insure the data Integrality. 8- supporting T=0 transmission protocol,Communication velocity supports 372/1 and 512/8. 9- Having the function that against inserting and pulling out of card when power on,and abnormal power off. 10- Supporting the algorithm of DES ,3DES ,COMP128-1 and have protection against attacking mechanism. 11- 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. 12- 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. 13- Perfect safety function and safety strategy,passed EAL4+safe authentication.
LTE USIM Card
4G LTE, Compatible with WCDMA and GSM
Blank or do programming in factory
3-in-1 SIM Card (Nano/Micro/Standard)
Main character of chip
CPU: - 8 bit CPU or 16bit CPU Memory size: 128K
EEPROM: - single byte read ,write, and wipe - multi bytes storage(1byte to1page) - program clock come from vibrate clock that generated by chip itself - At the normal temperature, can proceed at least 100,000 times erase and write operations. - EEPROM data endurance more than ten years - EEPROM program voltage generated in the chip
Serial I/O interface: - Match ISO/IEC-7816 - asynchronous half duplex transmission protocol - Two kinds of transmission velocity(372/1 and 512/8)optional Randomizer: -8- bit randomizer Power on reset - internal power on reset mechanism Low power work mode: - SLEEP mode - CLOCK STOP mode Safety mechanism: - Abnormal voltage/frequency detection function, DPA/SPS attacking immunity
