6pin 8pin SIM card Phone number can be programmable

Product Description:

This product is a GSM SIM card made of PVC material. It comes in different sizes and thicknesses, and can be customized according to your requirements. The card has a chip memory of 32K/64k/128k/256k/512k and supports various algorithms such as COMP_V1,V2,V3, CMCC_COMP_V0.

The SIM card is certified with ISO9001, CE, SGS and can write IMSI, ICCID, SID, NID, PIN, PUK AMD, AKEY, SMSC technological information into the card. It matches the standards of GSM11.11, GSM11.12, GSM11.14, GSM11.17, and ISO7816.

The SIM card has a modular design that allows for easy implementation of new functions. It has an optimized file management system that supports file access path selection. The card also supports STK data encryption and checkout, which matches the GSM03.48 standard.

It supports the norm of the China Mobile OTA2, Mass Storage Telephone Book, Group Sending Short Message, and other features. The SIM card has an inner backup mechanism to ensure data integrity. It supports T=0 transmission protocol, and communication velocity supports 372/1 and 512/8.

The SIM card has a function that prevents inserting and pulling out of the card when power is on and abnormal power off. It also supports the algorithm of DES, 3DES, COMP128-1, and has protection against attacking mechanisms.

The SIM card has a function of circuitry encryption and circuitry secrecy, preventing communication data from being stolen or juggled unlawfully. It can be used to check the data integrity. The SIM card has agile individuation instructions that not only ensure the requirement of safety management but also satisfy all kinds of customer’s requirements of pluralistic STK functions.
