Abstract
Embodiments described herein relate to managing access to an embedded universal integrated circuit card (eUICC) to obtain subscriber identity module (SIM) information without requiring cellular baseband wireless processing support. A baseband component of a wireless device that connects to the eUICC via a first interface can be in a reduced power state, and under certain conditions a processor external to the eUICC can access the eUICC via a second interface without booting up the baseband component to a normal (full) power state. When access to the eUICC via the first interface through the baseband component is required, the baseband component can be booted to a normal (full) power state to communicate with the eUICC. Additionally, a wireless device in which the baseband component is in a reduced power state or is absent can access one or more services of a mobile network operator (MNO) via a non-cellular wireless interface.
