Abstract
This Application sets forth techniques for managing subscriber identity module (SIM) toolkit (STK) scheduling for multiple enabled electronic subscriber identity module (eSIM) profiles on an embedded universal integrated circuit card (eUICC) of a wireless device, including managing multiple STK sessions at a baseband processor external to the eUICC of the wireless device. To forestall STK communication for different eSIMs from interfering with execution of processes associated with the eSIMs, a baseband processor can schedule STK sessions to avoid overlap and reduce opportunities for errors in handling eSIM processes. The baseband processor can prioritize whether to queue commands for a second STK session for a second eSIM until a first STK session for a first eSIM ends or to terminate the first STK session to handle the second STK session.
