Abstract
This Application sets forth techniques for binding and dynamic provisioning of international mobile equipment identifier (IMEI) values with cellular wireless service profiles, such as subscriber identity modules (SIMS) on physical SIM (pSIM) cards and electronic SIMs (eSIMs) on an embedded universal integrated circuit card (eUICC) of the mobile wireless device. When pSIMs and/or eSIMs change on the mobile wireless device, e.g., based on installation, activation, deactivation, de-installation, etc., IMEI binding logic accounts for the changes and maps IMEI values to pSIMs and/or eSIMs as required. IMEI values can be assigned based on a history of bindings between IMEI values and ICCID values of one or more eSIMS on an eUICC. A most recently used or a newly assigned IMEI value can be associated with an eSIM. Whether to assign an identical IMEI value to multiple eSIMs depends on requirements of associated cellular wireless service subscriptions.
