sysmoUSIM-SJS1 SIM + USIM Card (10-pack)


Right now, we are run out of stock with our cards and due to technical reasons, we have delays in restocking. Please do NOT request by mail when new cards will be available as we don't know. We try to restock as soon as possible. Just come by here from time to time to see if the situation has changed.

This is a bundle of 10 cards.

The sysmoSIM-SJS1 is a standards-compliant GSM SIM + UMTS USIM card (2FF + 3FF).

It is intended to be used in sysmoBSC based GSM networks, but can be used with any core network, even for UMTS (3G) and LTE.

All cards ship with factory-default unique IMSI and a card-individual random K + OPC.  The 2G SIM authentication is set to COMP128v1 and the 3G SIM application 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 ADM1 key is required for making any such modifications or to install Java applets.

sysmoUSIM supports:

  • GSM Authentication: COMP128v1 (default), COMP128v2 and COMP128v3, XOR, MILENAGE
  • UMTS Authentication: MILENAGE (default), XOR
  • Programmable ICCID
  • 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)

For more information on the sysmoUSIM-SJS1, please see the sysmoUSIM-SJS1 User Manual

The key material will be sent (at the time of shipping) by e-mail to the address submitted during the order/checkout process.

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!
