@jiska ok, thanks. Note I know nothing about iPhones, iOS or the Apple universum. All I'm basically looking for is the eUICCInfo2 which the eUICC returns when asking for it using a STORE DATA APDU after selecting the ISD-R. QMI can be used on other phones to talk to the eUICC, see https://programm.froscon.org/2024/system/event_attachments/attachments/000/000/857/original/FrOSCon_2024_-_eSIM_management_on_Qualcomm_phones.pdf @z3ntu
