This Application sets forth techniques for managing communication with wireless devices that have been flagged due to certain activity. In particular, the techniques effectively eliminate unnecessary interactions and enable enhanced user feedback when wireless devices that have been flagged are attempting to interact with mobile network operators (MNOs). The techniques can be implemented by a variety of entities to achieve different and efficient results under various scenarios. Such entities can include, for example, i) equipment identity registries that track unique identifiers of wireless devices that have been flagged due to certain activity, ii) MNO servers, such as SM-DP+ servers, and iii) wireless devices. Additionally, individual components within wireless devices can implement the techniques variously, including using issuer security domain root (ISD-R) components, local profile assistants (LPAs), electronic subscriber identity module (eSIM) components, and/or baseband components included in the wireless devices.

Techniques for managing communication with wireless devices flagged for certain activity

Techniques for managing logical channel communication for multiple electronic subscriber identity module (eSIM) profiles installed on an embedded universal integrated circuit card (eUICC), including mapping of logical channel identifier values between different logical channel labeling schemes are described herein. In a first scheme, logical channels are identified using logical channel values alone. In a second scheme, logical channels are identified using a combination of eSIM port value and channel values. An interpreter in the eUICC and/or in processing circuitry external to the eUICC can map between the logical channel labeling schemes to allow internal state machines in the eUICC and/or the processing circuitry to use the first scheme for identifying logical channels.

Logical channel management for multiple eSIM profiles

The described embodiments set forth techniques for securely transferring a cellular wireless service subscription associated with an electronic subscriber identity module (eSIM) profile from a source wireless device to a target wireless device via communication with servers of a mobile network operator (MNO). An MNO provisioning server encrypts an activation code, used for transfer of the cellular wireless service subscription, with a session key generated based on a one-time-use eUICC public key and a one-time-use server private key. The encrypted activation code is protected from malicious third parties, as only the eUICC of the source wireless device can perform the decryption required by generating an identical session key to recover the activation code. The eUICC of the source wireless device deletes the eSIM profile from the eUICC before providing the activation code to the target wireless device to protect against eSIM profile cloning.
