The sysmoISIM-SJA5 is a standards-compliant GSM SIM + UMTS USIM + IMS/VoLTE ISIM card. It has a triple-cut form factor, fitting 2FF (classic SIM), 3FF (micro SIM) and 4FF (nano SIM).
It is intended to be used in sysmoNITB / Osmocom based cellular networks, but can be used with any core network, from GSM (2G) through UMTS (3G) and LTE (4G) as well as 5G. It contains all files of 3GPP Release 17.
All cards ship with factory-default unique IMSI and a card-individual random K + OPC. The 2G SIM, USIM and ISIM authentication algorithm is set to MILENAGE.
One specific advantage of this card is its fully re-programmable nature, where the user can create/edit any files and directories (EF or DF) in the card filesystem.
sysmoISIM-SJA5 supports (bold is new compared to SJA2):
- GSM Authentication: XOR-2G, COMP128v1, COMP128v2 and COMP128v3, MILENAGE (default)
- UMTS Authentication: XOR-3G, MILENAGE (default), TUAK
- Fixed ICCID (not programmable/writable!)
- Programmable IMSI
- Programmable MSISDN
- Programmable Ki / K / OP or OPc (OPc default)
- GSM TS 11.11 compatibility
- 200 kBytes remaining/free flash
- Java enabled (Card Manager, OTA, STK/SAT)
- Card-individual ADM key
- Card-individual OTA keys (3DES default, AES optional)

NOTICE: This product is for operators of public or private mobile networks and the research community. As a regular subscriber of mobile networks, you cannot clone another identity to this card, as you do not know the secret identity (Ki) of your original card!
Custom printing available in quantities > 1000 units.
The cards all ship with an IMSI in the MCC-MNC of 999-70 (MCC 999 is reserved by ITU for private cellular networks). You can of course modify the IMSI like all other parts of this card to whatever is your requirement.
