sysmoISIM-SJA2 SIM + USIM + ISIM Card (10-pack)

This is a bundle of 10 cards.

The sysmoISIM-SJA2 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.

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.  Purchase of the card variant with ADM keys is required for making any such modifications or to install Java applets.

sysmoISIM-SJA2 supports:

  • 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
  • 64kByte flash size
  • Java enabled (Card Manager, OTA, STK/SAT)
  • Card-individual ADM key
  • Card-individual OTA keys (3DES)

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 currently all ship with an IMSI in the MCC-MNC of 901-70. This used to be an allocated-but-unused range several years ago.  However, this range has recently been re-allocated by ITU to an operator (Clementvale Baltic OY).  It is advised that you purchase the cards with ADM keys and change the IMSI to whatever MCC/MNC recommended by the regulatory authority in your jurisdiction. In Germany, there is e.g. a recommendeation to use the MCC "999" for private networks.
