It is intended to be used with Valid8 5G/4G Virtual Lab, Core Network Emulator or M5 UE Tester products, but can be used with any core network, including 2G GSM, 3G UMTS, 4G LTE and 5G NR. It contains all files of 3GPP Release 17 needed to test SIM cards.
SIM cards used to test 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.
Test SIM cards with cards are fully re-programmable, where the user can create/edit any files and directories (EF or DF) in the card filesystem.
