New Product: sysmoISIM-SJA2


After many years of supplying the world wide community of cellular researchers, academia and operators of private cellular networks for many years with the programmable SIM card sysmoUSIM-SJS1, it is time for a change:

Today, sysmocom announces the availability of the sysmoISIM-SJA2, the successor product to the sysmoUSIM-SJS1.

The major improvements include:

  • ISIM application for IMS/VoLTE (in addition to SIM + USIM applications)

  • pre-installed ARA-M applet for use with Android Carrier Privileges

  • only one product covering 2FF, 3FF and 4FF form-factor

  • All 3GPP-specified 5G related files on card

The new card of course includes all of the major features of its predecessor, such as:

  • modification of the contents of any file in the SIM, ISIM, USIM application (using AMD pin)

  • modification of key material, selected authentication algorithm and related parameters (using AMD pin)

  • installation of Java applets via GlobalPlatform SCP02 or TS 03.48 OTA

  • remote file management via TS 03.48 OTA

sysmocom has already ported the pySim and sysmo-usim-tool software, so both fully support the sysmoISIM-SJA2.

The cards are in stock and can be ordered via the sysmocom webshop
