Linkbit has delivered a new hardware: Linkbit SimArray Test Module. It allows Linkbit test platforms to access multiple real SIM cards registered in a MNO network. Any SIM card command defined by 3GPP TS 11.11 and supported by a specific SIM unit can be performed at any moment of test flow execution. A running test instance can access IMSI, ICCID or any other stored data, modify phone book, or make any other SIM operation normally made by a ME. The data received from the SIM card can be immediately used in testing network registration, authentication, PDP context creation, mobility and other aspects of UE behavior in a mobile network. SimArray Module may contain up to 64 simultaneously accessible SIM cards in a multi-user test environment. The cards are physically accessible and hot swappable on a live system.
