MsSIM allows full loading of multiple GSM carriers with a single test system. On each carrier, hundreds of simulated mobiles can concurrently generate load over the radio interface for both Circuit Switched and Packet Switched Services. MsSIM supports the GSM/GPRS/EDGE, Evolved EDGE and VAMOS standards, and the most recent additions include EC-GSM-IoT.
