Stk Support Modem

The term STK support in modems refers to the SIM Application Toolkit (SIM Toolkit), a standard (GSM 11.14 / 3GPP TS 31.111) that enables the SIM card to initiate proactive commands to the modem WikipediaMarketintelo. This allows for secure, menu-driven services (USSD/SMS) and over-the-air (OTA) updates independent of the device software.
