The USIM /USAT (USIM Application Toolkit) technology defined by 3GPP covers the STK (SIM Toolkit) functionality in 3G networks. The idea behind this is to enable the mobile network operators to bring value-added services (VAS) to existing networks and handsets. To ensure proper functioning, the protocols behind this must work smoothly.
