Our SIM cards are blank can be programmable, Not International Cards,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.
