This is a bundle of 10 solder-type SIM/USIM/ISIM chips in ETSI MFF2 form-factor.
The sysmoISIM-SJA2 is a standards-compliant GSM SIM + UMTS USIM + IMS/VoLTE ISIM card. It has a solder-type MFF2 form-factor.
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.
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.
- GSM Authentication: COMP128v1, COMP128v2 and COMP128v3, MILENAGE (default)
- UMTS Authentication: MILENAGE (default)
- Fixed ICCID (not programmable/writable!)
- Programmable IMSI
- Programmable MSISDN
- Programmable Ki / K / OP or OPC (OPC default)
- GSM TS 11.11 compatibility

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.
From September 2021 onwards, the cards currently all ship with an IMSI in the MCC-MNC of 999-70. The MCC 999 is reserved by ITU for private cellular networks.
Before September 2021, our cards used 901-70, an allocated-but-unused range several years ago. However, this range has recently been re-allocated by ITU to an operator (Clementvale Baltic OY). Subsequently we changed to 999-70.
