Abstract: Various embodiments include methods and devices for dynamically personalizing a wireless communication device. Embodiment methods may include analyzing a USIM AID (Application ID) list contained in the elementary file directory (EF-DIR) of an inserted SIM card for codes for personalization categories indicative of IMSI based, non-IMSI based, or both. Based on the 3G App code in USIM AID found in the EF-DIR, the corresponding personalization categories and values may be retrieved from ME database. The data required for personalization and their values contained in the inserted SIM card may be compared against the personalization category and values retrieved from the database. Access to camp on a mobile network may be dependent on the comparison of personalization category values and codes.

Abstract: Methods, systems, and devices for wireless communications are described. An example method may include identifying that a user equipment (UE) includes a first subscriber identification module (SIM) card in a first card slot of a plurality of card slots of the UE is associated with a first operator and associated with a first subscription for which use of the UE is subject to a contractual obligation to the first operator. The method may further include determining that the UE is in communication with a first radio access network of the first operator and communicating in accordance with a second subscription associated with a second SIM card in a second card slot, the communicating allowed based at least in part on the first SIM card associated with the first operator being in the first card slot and the UE being in communication with the first radio access network.

Abstract: Method and apparatus are provided for priority fallback of SUCI calculation. In accordance with some implementation, a UE may transmit, in response to receiving an indication of authentication failure for a first SUCI based on a first SUCI parameter, a second SUCI based on a second SUCI parameter different from the first SUCI parameter. In accordance with some implementation, the UE may further transmit a SUCI with NULL SUCI parameter if the UE determines all SUCI parameters supported by the UE has been rejected by the network.

Abstract: Methods, systems, and devices for recovery techniques for subscriber identification module (SIM) detection error are described. A user equipment (UE) may determine an operating mode for the UE based on a SIM card switch occasion. The SIM card switch occasion may be a “hotswap” occasion of a SIM card while the UE is powered on. The UE may power a SIM card associated with the UE based on the operating mode for the UE and a previous status of a SIM slot associated with the UE. The UE may detect a presence of the SIM card in the SIM slot based on powering the SIM card. The UE may set a SIM sensing operation at the UE based on the detected presence of the SIM card.

Abstract: A mobile device may be configured to determine, in a secure portion of the mobile device, whether a non-volatile indication (e.g., a fuse or non-volatile bit or flag) allocated to lender binding has been set. A mobile device processor may query a payment server associated with a lender of the mobile device to determine a next payment due date in response to determining that the non-volatile indication allocated to lender binding has been set, and select an operating mode for the mobile device based on a difference between the next payment due date and the current date.

Abstract: Methods, systems, and devices for multi-subscription management are described. A user equipment (UE) supporting a dual-subscriber identify module (SIM) configuration may identify a message to disable a subscription associated with a first SIM of a dual-SIM universal SIM (USIM) card. Disabling the first SIM may include powering down a modem stack associated with the first SIM while maintaining power to the first SIM. The UE may configure a SIM toolkit manager associated with a SIM toolkit for the first SIM to a disabled state based at least in part on the message. The UE may then indicate to the first SIM that the SIM toolkit manager is in the disabled state.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify an ongoing operation associated with a file of a universal integrated circuit card coupled to the UE. The UE may identify a request to access the file during the ongoing operation. The UE may suspend the request to access the file during the ongoing operation. The UE may process the request to access the file after completion of the ongoing operation. Numerous other aspects are provided.

Abstract: The apparatus determines whether a subscriber identification module (SIM) card is a first network SIM card or a second network SIM card. The apparatus performs an unlock sequence for personalization based on a subscriber permanent identifier (SUPI) if the SIM card is determined to be a first network SIM card. The unlock sequence may include determining whether a SUPI of the first network SIM card matches with a SUPI stored in a secure file system (SFS) at the UE. The unlock sequence may further include initializing the UE to a network if the SUPI of the first network SIM card matches with the SUPI stored in the SFS at the UE.

Abstract: The apparatus determines whether a subscriber identification module (SIM) card is an embedded universal circuit card (eUICC) or a non-eUICC while in a subsidy locked state. The apparatus performs a profile sequence to determine available network profiles if the SIM card is the eUICC. The apparatus may present an option at the user interface UI to switch network profiles on the UE if the current profile of the eUICC does not satisfy a personalization check on the ME.

Abstract: Techniques for detecting and correcting information modification in a mobile device are provided. An example method for detecting and correcting information modification in a mobile device includes: making a determination that locking configuration information for locking the mobile device for use with a wireless network of a wireless network operator has been modified; configuring the mobile device with restored locking configuration information in response to the determination that the locking configuration information has been modified; and performing operations using the restored locking configuration information in response to the mobile device being configured to use the restored locking configuration information.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may determine that initial subscriber information associated with a universal integrated circuit card (UICC) alone is insufficient to establish a secure connection with a 5G new radio (NR) based network, obtain additional subscriber information from a secure storage location which is separate from the UICC, generate a subscription concealed identifier (SUCI) based on the additional subscriber information along with the initial subscriber information, and establish the secure connection with the 5G NR based network based on the SUCI.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently personalizing or locking a user equipment (UE) for operation with a specific operator. For example, a manufacturer may load multiple operator configurations associated with multiple operators in UE storage such that the UE may support operation with any of the multiple operators. The UE may then allow a user to select an operator from the multiple operators, and the UE may select and apply an operator configuration corresponding to the selected operator to lock the UE for operation with the selected operator. Thus, using these techniques, a user may be able to dynamically personalize or lock a UE for operation with a selected operator. Further, after being personalized or locked for operation with one operator, a UE may be more easily re-personalized or locked for operation with a different operator.
