Abstract: A device described herein may receive an indication that the device is not authorized to access a first type of core network (e.g., a Fifth Generation (“5G”) Core (“5GC”)), and may detect that a first core network, of the first type of core network, is available for communication. The device may detect that a second core network, of a second type of core network (e.g., an Evolved Packet Core (“EPC”)), is available for communication. Based on the indication that the device is not authorized to access the first type of core network, the device may request establishment of a communication session with the second core network (e.g., in lieu of requesting access the first core network).

Abstract: A user equipment (UE), comprising at least one processor may be configured to transmit a first attach request to a first wireless network based on a first universal subscriber identity module (USIM). The UE may receive a rejection from the first wireless network and may switch from the first USIM to a second USIM based on the rejection. The UE may transmit a second attach request to the first wireless network based on the second USIM.

Abstract: A service provider may receive a user device that includes an embedded subscriber identity module (eSIM) associated with an equipment identifier (eID) with a previously provisioned service. The previously provisioned service may be provided by an eSIM profile (identified by an Integrated Circuit Card Identifier or ICCID) and the eSIM may contain more than one ICCID. The service provider may re-provision one of the existing ICCIDs to provide service based on the eID and historical data. The device and the carrier provisioning system may determine whether one of the profiles (ICCIDs) installed in the eSIM matches an already known eSIM profile (ICCD) and re-provision the eSIM profile (ICCD) for new wireless service. The service provider may then activate the user device for communication via the new wireless service in response to re-provisioning of the applicable eSIM profile (ICCID).
